Question

Consider the following sample data set.

0, 50, 66, 68, 69, 72, 74, 75, 12000

Manually calculate the mean and standard deviation of the set showing all calculations in a clear detailed table. Then, in a separate table, calculate the Z-score of each data point and indicate if it is a normal data point, a potential outlier, or an outlier. Remove any outliers and completely repeat this process. What do you observe about doing this?

Answer 1

and the last part that is removal of the outlier in the question can be done using python or R. Manually its a very long process so i was unable to give solution to that part of the question.

i hope my rest part of the ans is satisfactory:)) please do leave a like:) thankyou!
