C++ program to calculate measures of center (mean, median, mode) and measures of spread(Range, IQR, Standerd deviation, Variance)

Statistical Measures Calculator

This project is a C++ program designed to calculate various statistical measures for a set of numbers. It provides functionalities to calculate measures of center and measures of spread. The program allows users to input a set of numbers and then select the desired statistical measure(s) to calculate.

Features

• Calculation of Measures of Center:

  • Mean
  • Median
  • Mode

• Calculation of Measures of Spread:

  • Range
  • Quartiles (First Quartile, Third Quartile, Interquartile Range)
  • Standard Deviation
  • Variance

How to Use

1. Input

• Run the program and provide a set of numbers in a single line when prompted.

2. Select Type of Calculation

• Choose the type of calculation:
  • 1: Measures of Center
  • 2: Measures of Spread

3. Choose Specific Measure(s)

• Depending on the selected type:
  • For Measures of Center:
    • Select the desired measure: Mean, Median, Mode, or All.
  • For Measures of Spread:
    • Choose the measure(s) to calculate: Range, Quartiles, Standard Deviation, Variance, or All.

4. Repeat or Exit

• After calculation, you can choose to perform other calculations or exit the program:
  • Y: Yes to perform more calculations.
  • N: No to exit the program.

Instructions

• Ensure that the input set of numbers is provided in a single line, separated by spaces.
• Follow the prompts and input the appropriate choices as per the instructions.
• In case of wrong input, the program will prompt again to ensure correct input.

Implementation Details

The program is implemented using C++ and relies on the standard library. It includes functions to calculate various statistical measures such as mean, median, mode, range, quartiles, standard deviation, and variance.

Note

• This program assumes valid input for the set of numbers.
• For some statistical measures (e.g., mode), if there is no mode, the program indicates accordingly.
• For quartiles, if the number of elements in the set is even, it calculates the quartiles accordingly.
