What is a Five Number Summary?

A Five Number Summary is a descriptive statistic that provides a quick overview of the distribution of a dataset. It consists of five key values:

• Minimum: The smallest value in the dataset.
• First Quartile (Q1): The value below which 25% of the data falls.
• Median: The middle value that separates the lower and upper halves of the dataset.
• Third Quartile (Q3): The value below which 75% of the data falls.
• Maximum: The largest value in the dataset.

These five numbers offer a comprehensive snapshot of the data’s central tendency, spread, and potential outliers. Additionally, the Interquartile Range (IQR), which is the difference between Q3 and Q1, is often included to measure the spread of the middle 50% of the data.

How to Use the Five Number Summary Calculator？

1. Data Input

Locate the text area labeled “Enter numbers (comma or space separated)”.

Input your dataset into this field. You can separate numbers using commas or spaces. For example, you can enter “1, 2, 3, 4, 5” or “1 2 3 4 5”.

The calculator accepts both integer and decimal values.

2. Calculation

After entering your data, click the “Calculate Five Number Summary” button.

The tool will process your input and perform the necessary calculations.

The results will be displayed in the “Results” section below the button.

You’ll see the following values:

• Minimum: The smallest number in your dataset.
• Q1 (First Quartile): The 25th percentile of your data.
• Median: The middle value of your sorted data.
• Q3 (Third Quartile): The 75th percentile of your data.
• Maximum: The largest number in your dataset.
• Interquartile Range (IQR): The difference between Q3 and Q1.

By following these steps, users can easily analyze their datasets and gain valuable insights into the distribution of their data. The Five Number Summary Calculator provides a quick and efficient way to understand the central tendency, spread, and potential outliers in any given dataset.
