Answer #1

Mean of the values ( ) = (2.00+2.48+1.90)/3 = 2.127.

Average deviation (s) =

n is number of readings.

Hence

S = |2.127 -2| +|2.127-2.48| + |2.127 -1.90|/3

S = (0.127 + 0.353 + 0.227)/3

S = 0.235

So average deviation is 0.235.

    Write a program that computes the average and standard deviation of four scores. The standard deviation is defined to be the square root of the average of the four values. Use two functions. One function to calculate the average, this function should be with Return Type "double". Second Function should be to calculate standard deviation, this function should be with Return Type "void". Allow the program to continue until the user tells the program he/she is finished. This is for...
