Assignment Deliverable
Complete the following on the Data tab of the Pastas R Us data file:
- Calculate “Annual Sales” for each restaurant. Annual Sales is the result of multiplying a restaurant’s “SqFt.” by “Sales/SqFt.” The first value has been provided for you.
- Calculate the mean, standard deviation, skew, 5-number summary, and interquartile range (IQR) for each of the variables. The formulas and the first results have been provided for you.
- Create a boxplot (sometimes referred to as a box and whisker chart) for the “Annual Sales” variable.
- Create a histogram for the “Sales/SqFt” variable.
Respond to the following questions on the Questions tab of the Pastas R Us data file:
- Does the annual sales boxplot look symmetric?
- Would you prefer the IQR instead of the standard deviation to describe the dispersion of the annual sales variable? If so, why?
- Does the histogram show that the sales per square foot distribution is symmetric?
- If the sales per square foot distribution is not symmetric, what is the skew?
- If there are any outliers, which one(s)? What is the “SqFt” area of the outlier(s)?
- Is the outlier(s) smaller or larger than the average restaurant in the data? What can you conclude from this observation?
- What measure of central tendency may be more appropriate to describe “Sales/SqFt”? Why?
