STATISTICS: Final Project-ABBREVIATED
You are doing research on balance and fitness. To complete this research you will need use the excel data radomizer (provided) and analyze the data.
Identify a random sample from N = 20 males. You must answer this question:
*You analyzing the balance times for the 20 men in seconds.
Write a one paragraph introduction to your research, discuss how you selected your sample (is it a random sample?), and write a one paragraph conclusion. Present your data in an organized manner.
How do you establish that this sample is truly random?
All statistics are found in the excel spreadsheet.
You will analyze your data and compute the following statistics for each group:
Do steps 1 and 2 below at the same time b/c the values in the spreadsheet change each time you open the file:
Steps:
1) Compute the Population Mean, Variance and standard Deviation of the 20 men in seconds the subjects stayed balanced.
2) Identify a random sample of 10 men and find the sample mean (avaerage balance time in seconds).
3) Find he Median number of days per week exercised.
4) Find the Mode of the favorite exercise.
5) Find the RANGE FOR:
a) The Population Balance Times (20 males)
b) Your Chosen Sample Balance Times (10 males)
6) Pick 3 males and their Balancing Times, from the population and covert the times to Z-SCORES, using the z-score formula.
7) If the Z-SCORE from the population is Z = -2.20, convert this Z-SCORE to a RAW-SCORE.
8) Conclusion:
Describe what have you learnt after completing the project; and completing course work in statistics this semester.
