Chapter 3, Problem 2PP

Program Plan Intro

Program Plan:

Following variables are used in the program:

m variable is used to store the mean of four integers.

sdvariable is used to store the standard deviation of four integers.

number1, number2, number3, number4 are four variables to store four integers on which mean and standard deviation are to be performed.

Summary Introduction:

Program will use the Main () method, which will first calculate the mean of four integers and then use the mean to calculate the standard deviation. The formula used to calculate standard deviation is given as follows:

  $\sqrt{\frac{{\displaystyle \sum _{\text{i=1}}^{\text{n}}{\left(x_{\text{i}}-\overline{x}\right)}^2}}{\text{n-1}}}$

Program Description:

The purpose of the program is to calculate and display the mean and standard deviation for four integers.
