Here are some calculations that I should do with my files :

determine the number of data

determine the smallest value

determine the largest value

determine the extent of data

the arithmetical average

calculate the standard deviation of two sample

Data text file exemple :

22.08788214

98.58476277

90.30419021

66.95541915

71.69797604

88.34645813

24.89229343

79.37111899

I have done research and found nothing on getting my data calculated. Any good mathematician ? Thanks
