Description
Homework ContentPreparationReview the Wk 2 Summative Assessment: Pastas R Us Statistical Report assessment. Download the Pastas R Us data file.
Assignment DeliverableComplete 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? Submit your assignment.

Question
Does the annual sales box plot chart 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 distrubiton 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 database? What can you conclude
from this observation?
What measure of central tendency may be more
appropriate to describe “Sales/SqFt”? Why?
