Ungrouped Data Analysis

A C++ program to perform ungrouped data analysis. This program provides the median, mean, range, variance, standard deviation, quartiles, interquartile range (IQR), and the upper and lower limits for outliers.

How to use

1. First, the user needs to select whether the calculation is regarding a population or a sample.
2. Then, the user needs to enter the number of elements.
3. Finally, the user needs to enter the elements.

Example Input:

Your calculation is regarding?
(1) Population
(2) Sample

Select the number
2

Enter the number of elements
8

Enter the 1 element
9
Enter the 2 element
11
Enter the 3 element
12
Enter the 4 element
14
Enter the 5 element
15
Enter the 6 element
17
Enter the 7 element
20
Enter the 8 element
22

Output

The program will provide the following results:

• Median value
• Range value
• Variance value
• Standard deviation value
• First quartile (Q1)
• Second quartile (Q2)
• Third quartile (Q3)
• Interquartile Range (IQR)
• Upper limit for outlier
• Lower limit for outlier

Example Output:

Median value : 14
Mean value : 14.5

Range value : 13
Variance value : 25.75
Standard deviation value : 5.06815

First quartile (Q1) : 11
Second quartile (Q2) : 14
Third quartile (Q3) : 17
Inter Quartile Range (IQR) : 6

Upper limit for outlier : 25.5
Lower limit for outlier : 8.5
