*Descriptive
Statistics Project Requirement*

Using the raw data that you have gathered (as approved by your instructor), you are required to do the following:

1. Create a frequency distribution of at least seven classes.

2. Modify the frequency distribution to a percentage distribution and a less than cumulative distribution.

3. Construct a frequency polygon for your frequency distribution and the ogive for your cumulative distribution. Be sure to label your graph.

4.
From your frequency distribution, calculate the following descriptive
parameters: (*assume your data constitutes the population*)

a) mean

b) median

c) mode

d) standard deviation

e) variance

f) coefficient of variation

g) Pearsonian coefficient of skewness

h) kurtosis

5. Discuss the variability of your distribution (refer to the value calculated from 4f). Discuss the symmetry or skewness of your distribution (refer to the values calculated from 4g and 4h).

6. State the five-number summary. Draw a boxplot for your distribution.
