Engineers and swing dancing
Clayton
8/19/2014
The Question:
Are Engineers attracted to Swing Dancing?

3. In more detail: Is the percentage of swing dance engineers
significantly greater than the percentage of non-swing dance
engineers
2
Why this question?
It seems like almost everybody at a swing dance is an engineer
Is this because I live in Boston?
I have been a swing dancer for many years, and it has always
struck me as odd that there are so many engineers. I am curious
to find out if the quantity of engineers at our dances is a result
of the dance itself, or a result of high concentration of engineers
in the Boston area.
3
My Hypothesis
I believe the percentage of engineers at a swing dance is
significantly greater than the percentage engineers in the
general populace

4. I know Boston has a lot of engineers, but I personally think that
there is something about swing dancing that attracts them. If
my hypothesis is valid, then I will be able to consider “why”
they are attracted to swing.
4
The Variables
Whether or not a person is an engineer
Whether or not a person is a swing dancer
The analysis really only requires one variable, whether or not a
person is an engineer; however, whether or not a person is a
swing dancer is a significant part of reaching a conclusion.
5
Population
The population surveyed is active lindy hoppers in the Boston
area
Data for the general population is provided utilizing online
sources

5. It should be noted that there are many forms of swing dance,
and I have chosen to just focus on one type, Lindy Hop, due to
knowing the scene well and being able to make all of the major
dances. Research was done ahead of time to make sure general
population statistics were available online
6
Data Collection
Lindy hop data
Data collected over one week at the three major swing dances in
the area
Most of the dancers at each dance were surveyed
The survey asked for information about where the participant
lived, what they did for work, as well as some other questions
related to years dancing, education, and gender
Population of the area data
Data collected using a Census search tool that can be found at
http://factfinder2.census.gov/faces/nav/jsf/pages/index.xhtml
Based off 2012 census data
Most of the dancers refers to me going to everybody I could get
to at each dance. I first asked permission, then made sure I had
not already spoken to them. I would venture that I was able to
get to 80%+ people at the first dance, and 95%+ people at the
second two dances. I also asked some other questions that were
unrelated to this project in hopes that I could garner some other
statistical data that might be helpful to know.
7

6. Possible Bias
Not everybody was surveyed at the dances
I only was able to survey people at the dances, missing people
who were not there that week
Only one type of swing dance was covered
Census data was from 2012 (the most current available)
I could not come up with a way to do a random sample while
surveying at the dance, so I decided to go after the whole
population. This lead to some convenience bias’ (mentioned
above). The census data not being current is a form of
measurement bias that was impossible to avoid.
8
Organizing the Data
The survey initially yielded 230 data points, but the places
where the candidates lived were all over the place.
I chose to work with the top seven locations of participants:
Arlington, Boston, Brookline, Cambridge, Medford, Newton,
and Somerville.
This narrowed my data points down to 135, and made it possible
for me to gather necessary data from the US census website.

7. If I had wanted to use all of the locations (including
international), I would have had to gather population statistics
for each of the places listed in response to the survey. Due to
the fact that the study is meant to compare a local swing
population to it’s general population, I decided to only use the
places that had representation of 4 or more participants. It just
so happens that the places used account for a good portion of
the major cities in metro Boston. This does add a caveat to my
results, however, since this is now a test for these cities rather
than all of the Boston area.
9
Testing the Hypothesis
The null Hypothesis (H0) is that the outcomes of the sample
group (the swing dancers) will be relative to that of the general
population (census statistics)
The alternative Hypothesis (HA) is that the outcomes of the
sample group (the swing dancers) will be significantly different
from that of the general population (census statistics)
A Goodness-of-fit Chi-square test will be used to analyze the
data
The level of significance will be: alpha = 0.5%
Due to this not having multiple variables to work with, it is
impossible for me to do a Chi-square test hypothesis test for
independence. I did some research and came across a goodness-
of-fit chi-square test that works with my data. I considered
forcing the test for independence, but realized that it just was
not a good fit.

8. 10
Initial Analysis – Bar Graph
Once I had my data, I used the occupation categorization that
the US Census utilizes to assign the participants into an
occupation group. This graph is a comparison of the swing
populations job distribution compared to the general
populations job distribution. 1300-1560 is the comparison most
related to this study as it includes all engineering job-types.
The bar graph shows a large difference between the two
populations.
11
Goodness-of-fit Chi-Square Test
The p-value is less 0.05%, therefore we can reject H0 and
accept HA

9. 12
Results
Based on the bar graph, we can see that the percentage of
engineers at a swing dance is far greater than the percentage of
engineers in the general population of the cities used in this
test.
Combined with the significant results from the Goodness-of-Fit
Chi-Square test, we can say that my hypothesis is correct: The
percentage of engineers at a swing dance is significantly greater
than the percentage engineers in the general populace!
The statistics are in! We are correct!
13
Reflection
Positive experiences
Discovering an alternate test for my analysis was a huge relief
The conversations I was able to have with curious participants
were wonderful. Most of them are very curious to learn about
my results
Negative experiences
Realizing that the chi-square test for independent variables did
not apply!
Parsing the census data
Surprises!
Additional data provided very interesting information: like19/20
of the engineers in my sample were male
Most of the engineers only have a bachelors, yet I assume they
make twice as much as me

10. I really enjoyed doing this project. The topic has come up so
often between myself and my friends, and now I can say that it
is indeed true, engineers are attracted to swing dancing. There
were some tough parts of putting this together, but I learned a
lot.
14
Moving Forward
I wish I could conduct this study in multiple cities to find out if
the results are similar.
Now I know there is a statistical significance in the amount of
engineers, but that does not explain why.
I think a proper study would also cover the other forms of swing
dance.
I am definitely going to analyze the data for other results as
well that will be useful to the swing scene (How many
newcomers in a week? How educated are swing dancers? What
is the average amount of time a person has been a swing
dancer?)
It is a pity that I can only collect this data for Boston. I am so
curious to find out if it is a product of our city (we do a lot of
recruiting at MIT), or if this is world-wide (dancers from other

11. scenes say they have tons of engineers). If the results in other
cities are similar, then maybe I can start theorizing about why
engineers are attracted to the dance (maybe because it has a
formula… who knows?).
I also look forward to providing information to the leaders of
the swing scene about years people have danced and other
interesting facts.

SECTION 1
REPLIES TO PAM, MEGHAN, STACY : Engage in a
meaningful discussion of the student’s understanding and the
pedagogical approaches for each situation. You might also make
connections to your own teaching. Would you expect a similar
response from your own students? If not, why not? Have you
experienced similar questions in your own classroom? If so,
how have you handled them.

Student 1--
Problem D2 showed two box plots, one for the boys’ heights
and the other for the girls’ heights.
In Problem D2, Monique stated that: "It looks like just 12.5% of
the boys are taller than all of the girls, and maybe about 10% of
the girls are shorter than the shortest boy." That was not a
correct interpretation of the box plot. 12.5% is half of 25%, so
Monique might have got that value from an understanding that
box plots can be broken into four groups of 25% of the data. I
think the 10% value was an estimate. The difference between
the shortest and tallest student was 14 inches. The difference
between the shortest boy and shortest girl was 2 inches. The
ration of 2 to 14 is not the same as 1/10, but I wonder if the
height values are what she used to estimate.
My next instructional move would be to ask Monique how she
came up with the value of 12.5%. I would find out if Monique

56. knew how the box plots were created and how to interpret the
results. I would provide Monique with the boys’ raw data or
have her create the data set from the dot plot. I would ask
Monique to tell me what a box plot represents and what the
different parts mean. I would ask her to show me how to find
the five-number summary, all the while scaffolding any parts
she needs help with. Finally, I would ask her to compare the
data set broken into four groups to the boys box plot and I
would ask if her thoughts on the boys’ data changed and how. I
would also ask her how she came up with the 10% value and
possibly have her redo the steps with the girls’ data.
Student 2
In Problem D2, Arketa stated that: "There is a lot of overlap in
heights between the boys and girls." That is a true statement,
but it is very broad. Is Arketa talking in terms of the middle
50% of the data or the full range of the data?
My next instructional move would be to ask Arketa for more
information. Where does the data overlap? How does it
overlap? Why is it significant? Is the overlap of the boxes the
same as the overlap of the whiskers? Why or why not? What
does that mean?
--Meghan
I looked at the K-2 strand. In this strand there were many
student obsevations about the data they collected. Below are the
two reponses I chose to discuss.
Sahar: "I think there will be between 32 and 38 raisins in that
[unopened] box because most of our boxes had between 32 and
38."
This student clearly understands the idea of using what they
observed to help make a prediction. Thes student was able to
look at where the data was "clumped" to help understand that
most of the boxes they opened had this number of raisins. My
next step with this student might be having them try to find the

57. median. This would help the student to find that middle value
so that maybe they could use one value to make a prediction
rather than a range of calues.
Isaiah:
"Look at that gap with the blue dots -- and there aren't any gaps
on the green dots."
This student is looking at the data and definitely comparing two
different graphs. This student had a more observant response
than some of the other classmates because they were more fixed
on the vertical aspects of the data while this student also looked
at the spread. My next step for this student would be to get
them using the correct vocabulary. Have the student use spread,
and outlier to talk about this data.
Stacy…..
Hi All,
I teach second grade so I looked at the data and case study for
the K-2 interval. My observations about the studnets are
included below.
Sahar and Paul- Mr. Mitchell’s Class
Sahar: "I think there will be between 32 and 38 raisins in that
[unopened] box because most of our boxes had between 32 and
38."
Paul: “I think there will be 34 raisins in that [unopened] box,
because 34 had the most."
I think these two students demonstrate an understanding of
central tendencies and ‘typical’ values when they make
predictions about how many raisins would be in an unopened
box. The idea of the mode being the value that appears most
often is evident in Paul’s response and the idea of most of the
data being contained in a cluster is evident in Sahar’s response.
Both students accurately use these measures to make predictions
about the unopened box of raisins.
Since these students seem to have a good understanding of how
to interpret the data and identify ‘typical’ values the next step
would be to assign statistical vocabulary such as ‘mode’ and
‘cluster’ to the concepts that each student highlights.

58. Additionally, I may present these students with a data set that
appears to be bimodal (maybe the second pocket data line plot)
to see how they use what they know about modes and clusters to
identify ‘typical’ values.
Ramel: Mr. Mitchell’s class
Ramel: "The range is from 25 to 43."
From this statement it is clear that Ramel has a
misunderstanding relating to the meaning of the vocabulary
word ‘range.’ His statement indicates that he considers the
range to be the distance between the smallest and largest
number represented on the axis of the line plot rather than the
distance between the smallest and largest VALUE represented
on the line plot. He does however have a foundation for
understanding the range as he understands that it encompasses
the distance between two values; namely the smallest and
largest.
The next step for Ramel would be to review the meaning of the
term ‘range’ and how it is found. His current statement has
simply identified the interval for the range, he has not actually
calculated the range (difference between the largest and
smallest value). I may give him a few examples of the range,
then have him work with a buddy to find the range on his own
with other data sets and then return to the raisin data and ask
him “after reviewing the term range can you revise your
statement about the range of the raisin data?” This way he will
be able to see and correct the error he made previously.
SECTION 2
REPLIES TO #1,2,3,4: Make strong connections between the
course and your practice. Take this opportunity to wrap it up
together, in a nice bundle you can walk away with!
1. BRING IT BACK---RICHARD
I am going to write this as if I were meeting with my 7th grade
teaching peers. We really work well together and enjoy

59. bouncing ideas off each other.
While much of this course dealt with concepts above our
students expected knowledge level. I am going to address the
parts that I would expect them to know or be able to learn. This
course started with a review of measures of central tendency.
This is more of a 5th/6th grade standard in Massachusetts, but it
is important to review these concepts to ensure understanding. I
am constantly surprised at how much students forget over the
summer. It is important for students to be able to create and
analyze multiple representations of data in the form of bar
graphs, histograms, box plots, scatter plots, and frequency
tables. In addition, using technology to create these
representations will allow more time thinking about the meaning
instead of the creation of these models.
Once these models are created, students need to be able to
identify and quantify the spread. Specific application to our
grade level would include IQR and MAD. Standard deviation is
something they will calculate in high school, but it is important
to know what they will be learning in years to come. If the
opportunity presents itself, we can expose them to this concept.
One other concept that applies indirectly to our grade level is
probability. In this course, we looked at probability through the
Empirical Rule. This could tie together probability and even
solving equations. I would not expect them to understand the
Empirical Rule, but they should be able to find probabilities
from given standard deviations. I would envision this as an
enrichment activity because of the attention to detail needed to
solve these problems.
Also as enrichment, we could discuss bivariate data. This is a
major concept in statistics and probability in the 8th grade
curriculum. It can be an extension of representing proportional
relationships in a graph, table, or equation. It would be an
opportunity for them to see that in the real world, data doesn’t
always fall exactly into an equation and we have to apply the
line of best fit.
There are two specific parts of this course that I would present

60. to my colleagues. The data set and questions on How Do
Students Value Statistics is a rich activity with specific
application to 7th grade. I also really enjoyed all the
Annenburg segments. They are well developed and lead
students through the discovery process. Ultimately this is a
better way for students to learn.
2. RANDALL
There is so much that I have learned in this class. Statistics are
part of everyday life and for you to get the most out of the data
that is given to each and every one of us it is imperative that we
know how to read and interpret the data. Data can be
manipulated so that whatever the entity that is presenting the
data can make it look so that the data will support whatever
agenda that entity has. Knowing the difference between the
mean of a set of data and the median of the set of data can make
all the difference in the world on the interpretation of that data.
Knowing the Empirical Rule makes it very easy to predict the
probability of an event occurring. Standard deviation allows
one to see which data is truly important and which data doesn’t
have an effect on the process. Just today in my Algebra 2 class
we are taking data, making a scatter plot, finding the trend line,
the equation of the trend line and the correlation coefficient. I
am doing all of this on the TI -84 Plus calculator and the
students are amazed at the results they are getting. I have
already, on the third day of school, used what I have learned in
this class and I am much better prepared to explain any
questions that the students have. I would recommend this class
to any math teacher in the secondary level so that he/she can
become a better teacher and prepare our students today to life
tomorrow.
3. PAM
This course has shown me how critical it is for students, and
adults, to understand how to interpret and how to use statistics
in everyday life. The statistics strand in math is one that we
encounter and apply on a regular basis.

61. There are many things from this course that I can bring back to
my classroom. Things that come immediately to mind (in no
particular order) are vocabulary, how statistics fit into the
common core standards, activities and applets used in this
course, the meaning of center in a data set and using a project to
apply the concepts we learned.
All of the vocabulary that we learned during the first week
seemed overwhelming. I could not tell the difference between a
variable and an observational unit. As the weeks went on, the
new words became part of my own vocabulary. Our students
benefit from exposure to math vocabulary on a constant basis.
Another thing that I will bring back to my practice are the
newfangled ways to say box and whisker plot (box plot), stem
and leaf diagram (stem plot) and line plot (dot plot). I noticed
the newer versions of those terms as I went through the common
core standards for the grades below and above mine, so now is
the time to use them!
Some of the Annenberg activities (such as having students use
the number of people each lives with to create a data set for
summarizing and graphing), and applets, are pertinent for
teaching statistics in 7th and 8th grades. In 7th grade we work
with measures of central tendency and measures of variation
(MAD, in particular) and in 8th grade we use bivariate data to
create scatter plots and find the line of best fit (an
approximation, only). Some of the applets show how to cut to
the chase, so to speak.
I can also use ideas from the NCTM articles we read. Finding a
balancing point in a data set might help my 7th graders be able
to put mean, median and mode into context. Using the
previously mentioned family size data to help students
understand how distribution works can lead into our unit on
MAD, as it did in the article.
