### Instructions:

MATH 106 Statistics Project Instructions (Revised May 2016)
For this assignment, you will implement a project involving statistical procedures. The topic may
be something that is related to your work, a hobby, or something you found interesting. If you
choose, you may use the example described below.
report in order to qualify for full credit:
o Yourself (student’s name)
o name of project
o purpose of project
- Task 2: Conduct Data Collection. Provide:
o Raw data used (sample size must be at least 10 individual raw scores)
o source of the data
- Task 3: Calculate Measures of Central Tendency and Variability:
o median, sample mean, range, sample variance, and sample standard deviation
(show work)
- Task 4: Frequency Distribution. Provide
o Raw data in frequency table format (1 st column of value “intervals”, and 2 nd
column shows “frequency”: number of scores falling within each interval)
o Create histogram using frequency table constructed in Task 4
o NOT a vertical bar chart!
o x – axis must show intervals, y – axis must show frequencies
- Task 6: Compare Raw Data Distribution to “Standard” Normal Distribution. Using your
raw data gathered in Task 2 and the sample mean and sample standard deviation
o percentage of your raw data falling within one standard deviation of the mean;
o percentage of your raw data falling within two standard deviations of the mean;
o percentage of your raw data falling within three standard deviations of the mean

I recorded spent data in 10 different days
Task 3 Calculate Measures of Central Tendency and Variability:
Median
Rearranging the data: 33,33,35,37,38,39,40,42,47,50
Median is (38+39)/ 2= 38.5
Sample mean
Σ=37+40+50+33+42+38+39+35+47+33=394
Mean = Σ/n=394/10=39.4
