assignment.
In preparation for writing your report to senior management
next week, conduct the following descriptive statistics analyses with
Excel. Answer the questions below in your Excel sheet or in a separate Word
document:
Insert
a new column in the database that corresponds to Annual Sales. Annual
Sales is the result of multiplying a restaurants SqFt. by
Sales/SqFt.
Calculate
the mean, standard deviation, skew, 5-number summary, and interquartile
range (IQR) for each of the variables.
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
variables dispersion? Why?
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?
What
measure of central tendency is more appropriate to describe Sales/SqFt?
Why?
