Question 1: How many classes will the Frequency Distribution Table have for this data set?

What is the Class Width for each class?

When looking at the Frequency Distribution Table, what is the lower x-intercept?

When looking at the Frequency Distribution Table, what is the upper x-intercept?

What is the mean (arithmetic average) for this data set? (round your answer to 4 decimal places).

What is the median for this data set? (report your answer to 4 decimal places)

What is the midpoint of the modal class for this data set? (report your answer to 4 decimal places).

What is the relative frequency of the modal class for this data set? (report your answer to 4 decimal places)

What is the standard deviation for this data set? (round your answer to 4 decimal places)

What is the Coefficient Of Variation for this data set? (Note: COV is a % reported to 2 decimal places, like "12.34%" so remember to use the % sign after the numerical answer.)

Viewing the graph of the histogram, how would you correctly describe this distribution? Is it: bell-shaped or right skew or left skew?

Which measure of central tendency should be used to interpret this data set? Is it: mean or median or midpoint of the modal class? (Hint: refer to the handout, Interpretation of Statistical Results).

Refer to your answer in Question # 12. Why is the correct choice for the measure of central tendency in Question # 12 the preferred choice? (Hint: refer to the handout, Interpretation of Statistical Results).

Refer to Question # 1 which states the purpose for this research. Considering the purpose for this research, how can the mediator use the descriptive statistics information to help settle the wage dispute?
