Does number of AP students effect sanity?
WHY HOW PLAN
Chose this topic First we collected a We plan on
because we came SRS of FP students analyzing this data
to realize due to then those students by using a chi-
personal were given a survey square test
experience that the that should give us a
more classes we close approximation
took, the to their sanity levels
more…insane…we
began to feel.

4. Summary of Experiment
Collection process: Problems encountered:
We collected our data by People not wanting to
giving every student a fill out our survey.
number and calculating
an SRS of 41 students to
take our survey
5. data
0 1 2
1-4 3 2 4
5-9 7 6 8
As you can see by our data we found that no one that took our survey was labeled as
‘insane’.
6. Summary of Research
1)Ho: There is a relationship between number of ap classes and sanity. <.05
Ha: There is no relationship between number of ap classes and sanity. >.05
=.05
2)2-variable chi-square test:
srs-yes
all expected counts>=1
80% of expected counts>=1
3) DF=(3-1)(2-1)=2
chi-square: (o-e)^2/e (3-2)^2/2……….(12-2)^2/2
chi-square=4.86159
p-value=.0906
4)Since our p-val=.0906> =.05 we do not have enough evidence to reject the Ho therefore AP classes may not have an effect on
sanity
7. Final Summary
Due to the fact that our p-value was greater then our
alpha value we inferred that sanity is not effected by
number of ap classes.
We could have improved our study by increasing our
sample size to get a larger sample of people who
have a higher amount of ap classes
Limitations we faced for this experiment was our time
frame to collect data since due to the low amount of
time our sample size was small
We could have addressed people to better answer of
question of interest by offering them food or possibly
candy if they are truthful.
