Questions

Question	Answer
Does the annual sales box plot chart look symmetric?	The annual sales box plot chart does not look symmetric.
Would you prefer the IQR instead of the standard deviation to describe the dispersion of the annual sales variable? If so, why?	Yes, I much prefer to use the interquartile range (IQR) to illustrate the variability of a variable rather than the standard deviation since the IQR is unaffected by extreme values.
Does the histogram show that the sales per square foot distribution is symmetric?	There is not a symmetrical distribution for the number of sales that occur per square foot.
If the sales per square foot distrubiton is not symmetric, what is the skew?	The distribution of sales based on square foot, as well as its skew, is 1.24.
If there are any outliers, which one(s)? What is the “SqFt” area of the outlier(s)?	Lower limit: 106.77, Upper limit: 709.64, The outliers have the following values: 987.12, and their square foot area is equivalent to 1250. The restaurant has an average space of 2580.50 square feet per location.
Is the outlier(s) smaller or larger than the average restaurant in the database? What can you conclude from this observation?	The sales per square foot outlier has a smaller footprint than the typical eatery. This demonstrates that a smaller restaurant can still be lucrative thanks to its ability to achieve higher revenues per square foot.
What measure of central tendency may be more appropriate to describe “Sales/SqFt”? Why?	Sales per square foot data is right skewed, as seen in Part 4, hence a preferable central tendency metric that is not influenced by outliers would be the median.
