Assignment: Statistics Analysis
Conduct the following descriptive statistics analyses with Excel. Answer the questions below in your Excel sheet or in a separate Word document:
o Insert a new column in the database that corresponds to "Annual Sales." Annual Sales is the result of multiplying a restaurant's "SqFt." by "Sales/SqFt."
o Calculate the mean, standard deviation, skew, 5-number summary, and interquartile range (IQR) for each of the variables.
o Create a box-plot for the "Annual Sales" variable. Does it look symmetric? Would you prefer the IQR instead of the standard deviation to describe this variable's dispersion? Why?
o Create a histogram for the "Sales/SqFt" variable. Is the distribution symmetric? If not, what is the skew? Are there any outliers? If so, 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?
o What measure of central tendency is more appropriate to describe "Sales/SqFt"? Why?
Format your assignment according to the following formatting requirements:
o The answer should be typed, using Times New Roman font (size 12), double spaced, with one-inch margins on all sides.
o The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
o Also include a reference page. The Citations and references must follow APA format. The reference page is not included in the required page length.
