Statistics Survey Presentation and Limitations

1. UNIT 4
PROJECT
MAT 152-FALL ‘21

2. Parts 1 & 2
Question: Is there a difference in perception on the importance of going to church
regularly, between Delaware adults over and under 50 years old?
To carry out this study, I asked 30 random adults who were in a cafe queue downtown,
the following questions:
1. Are you originally from this State?
2. How old are you?
3. Do you consider that attending church regularly, is important for an individual’s
quality of life?
Population: Adults from Delaware.
Sample: Random adults from some cafe queue downtown.

Results

4. Part 6
I have collected the sample from a cafe que which is mostly
a gathering point for adults. It would have better if:
Sample was collected from more than one place.
Sample does not have even portion of quantitative
variables under observations, so may be a larger sample
with even portion of over and below 50 years old people
have better results.
A portion of sample includes outsider which also
decreases the number of effective responses.
A. Quality of Sample

5. Part 6
Age is used as quantitative variable in the data, which may
not be enough for the study such as respond time, which
may measures the interest factor of the respondents.
For categorical variables gender inclusion may have
provided better understanding of the perception.
A. Quantitative Variables

6. Part 6
For categorical variables gender inclusion may have
provided better understanding of the perception.
Response of yes or no is also categorical variable i.e., how
many people said yes or no to the question asked
A. Categorical Variables

7. Part 6
This was not even representation of the sample as it has
65% representative with age less than 50.
A. Responsive variable

Age, if from this
state
< 50 >= 50

8. Part 6
Study was purely observation as it measures only how
much population of Delaware is going to church.
As this was observational study in does not go any
further what changes are being observed in these two
categories of people.
Each two responses are observational and don’t have
any further dependent variables

9. Part 6
If I have added two or more variables which tells change in
life of the people, which are going to church, would have
made my study experimental.
Those experimental responses will be dependent on my
original responses sampled above.
B. Experimental Study Part

10. Part 6
If I have used place like church and some other places
diversity of the location would have made my study more
accurate.
Respondents were given to choose between yes or no in
short time in public place. So, this may have impacted the
response.
If the question have included number of time to church in
a week or month, this may be more accurate to get into the
mind of the respondent.
C. Limitation of the study

11. Part 6
Addition of more responses can be made possible.
With an additional question and giving choice to respond
on will may add more value to the accuracy.
Results are reliable based on the responses collected but
these results can be further improved by minimizing above
limitations.
C. Limitation of the study

12. Part 6
To try and reduce the biasness, I didn’t ask for the name of
the respondents.
Environment of the Reponses was not under any influence
or stress. I.e., Reponses were not collected in front of
family members or in presence of class teachers.
D. Respond Biasness

13. Part 6
Selections was not biased as a que without any prior
knowledge of their age was selected.
The biasness in the study may present somehow as data
include more people under 50 years of age.
Also it does not consider the gender factor.
Another biasness may present as it does not count the
people who don’t want to respond the question.
