Write a program that computes the central tendencies mean av

Write a program that computes the central tendencies mean (average), mode, median and the variation: variance, standard deviation and range for a set of numbers given in the data file ArsenicGroundWaterFile.txt.

The following data represent (naturally occurring) concentration of arsenic in ground water for a random sample of 102 Northwest Texas wells. Units are parts per billion.
Reference: Nichols, C.E. and Kane, V.E., Union Carbide Technical Report K/UR-1

The output should be as follows to two decimal places:

Central Tendency Variation   

Mean xxx.xx Variance xxx.xx

Median xxx.xx Std. Dev xxx.xx

Mode xxx.xx Range xxx.xx
