Chapter 11, Problem 1PE

Modified statistics program

Program plan:

• Import the necessary modules.
• Define the “mean()” function,
  • Returns mean value to the caller.
• Define the “StdDev()” function,
  • Returns standard deviation value to the caller.
• Define the “meanStdDev()” function,
  • Returns average standard deviation value to the caller.
• Define the “median()” function,
  • Returns median value to the caller.
• Define the “main()” function,
  • Get comma separated values from the user.
  • Separate the value based on “,” using “split()”.
  • Create a “for” loop to iterate over comma separated values.
    • Assign the value.
      • Print the options.
      • Create sentinel loop to get numbers.
      • Prompts the user for the type of operation to perform.
      • Check whether the operation is “Avg” using “if” .
        • If it is true, print mean value return from “mean()” function.
      • Otherwise, check whether the operation is “Med” using “elif”.
        • If it is true, print median value return from “median()” function.
      • Otherwise, check whether the operation is “Std” using “elif”.
        • If it is true, print standard deviation return from “stdDev()” function.
      • Otherwise, check whether the operation is “AvgStd” using “elif”.
        • If it is true, print average standard deviation value return from “meanStdDev()” function.
      • Otherwise, check whether the operation is empty (‘ ‘)using “elif”.
        • If it is true, use “break” to exit.
        • Otherwise print “Please try again”.
• Call the “main()” function.
