Introduction

The Median IQR Calculator is designed to quickly and accurately compute the following statistical measures:

  • First Quartile (Q1): The median of the lower half of the data.
  • Second Quartile (Q2 / Median): The middle value of the data set.
  • Third Quartile (Q3): The median of the upper half of the data.
  • Interquartile Range (IQR): The difference between Q3 and Q1.
  • Median (Q2): A measure of central tendency.
  • Minimum: The smallest value in the data set.
  • Maximum: The largest value in the data set.
  • Range (R): The difference between the maximum and minimum values.

How to Use

  1. Input Your Data:
    • Enter your data set into the input box. The data should be a collection of numerical values separated by commas (e.g., 5, 12, 18, 23, 7).
  2. Select Calculation:
    • Choose the statistical measures you’d like to calculate (Q1, Q2, Q3, IQR, Minimum, Maximum, Range).
  3. Click “Calculate”:
    • Press the “Calculate” button to process the data.
  4. View Results:
    • The calculator will display all requested measures instantly, providing you with a clear summary.

Example

Data Set: 4, 8, 15, 16, 23, 42

  1. Input: Enter the values: 4, 8, 15, 16, 23, 42.
  2. Select Calculations: Choose to calculate all statistics.
  3. Results:
    • Minimum: 4
    • Maximum: 42
    • Range (R): 42 – 4 = 38
    • First Quartile (Q1): 6
    • Second Quartile (Q2 / Median): 15
    • Third Quartile (Q3): 19.5
    • Interquartile Range (IQR): Q3 – Q1 = 19.5 – 6 = 13.5

In the following, you can see the output using the online calculator.
