Using the data set that you identified in week 1, use Excel to find the following descriptive statistics for the price data.
Descriptive statistics:
Mean
Median
Standard Deviation
Use these summary statistics to make two conclusions or observations about the typical vehicle in the sample. One conclusion must relate to the measure of center (mean/median) and one to the variability (standard deviation) of the vehicles.
Next, add an 11th vehicle to the data set. Choose a “supercar” that costs at least $1 million. Recalculate the summary statistics to include this vehicle.
Descriptive statistics:
Mean
Median
Standard Deviation
Which summary statistics were affected the most by the addition of this outlier? How were they changed, and were you surprised by the results?
