## Five Number Summary Calculator: Find the Distribution Of A Dataset

### Input comma-separated values and calculate the five number summary

The Five Number Summary Calculator provides a clear snapshot of your data with five key values: the minimum, 1st quartile, the median, 3rd quartile, and the maximum.

Offering a simple summary of your data’s range and center makes it easier for you to grasp the overall pattern.

Learn about what the Five Number Summary Calculator is, how it works, and why it’s such a valuable tool for analyzing your data.

## What Is The Five Number Summary Calculator?

A Five Number Summary Calculator gives a quick overview of a dataset using five key values. It starts with the minimum (the smallest number), followed by the first quartile (Q1), which shows where 25% of the data falls.

The median (Q2) is the middle value when the data is sorted, dividing it into two equal parts. The third quartile (Q3) indicates where 75% of the data falls, and the maximum is the largest number. These values together summarize the data’s spread and center.

In addition to these, the Five Number Summary Calculator can also provide:

**Mean (Average)**: This is calculated by dividing the total sum of all data points by the number of data points.**Count**: The total number of data points present in your dataset.**Sum**: The total sum of all your data points.

## Calculation Process

To calculate a Five Number Summary, start by sorting your dataset in ascending order. This step is essential as it helps you accurately determine the quartiles and the median’s position within your dataset.

### Sorting the Data

Begin by arranging your dataset in ascending order. Sorting is key to accurately finding the quartiles and median.

### Identifying Key Percentiles

#### Minimum (Min)

This is the smallest value in your dataset. After sorting, it’s the first value.

#### Maximum (Max)

This is the largest value in your dataset. After sorting, it’s the last value.

#### Median

This is the middle value when your data is arranged in ascending order. If the dataset has an odd number of values, it’s the exact middle value. If even, it’s the average of the two middle values.

#### First Quartile (Q1)

This represents the median of the lower half of your dataset, representing the 25th percentile. After splitting the dataset into two halves, find the median of the first half.

#### Third Quartile (Q3)

This represents the median of the upper half of your dataset, representing the 75th percentile. Similarly, after splitting the dataset into two halves, find the median of the second half.

### Additional Statistics

#### Mean (Average)

This is the arithmetic average of your dataset. To calculate it, sum all the values and divide by the number of values.

#### Sum

This is the total of all values in your dataset. Add together all the values.

#### Count

This is the total number of values in your dataset. Simply count all the values.

## How to Use the Five Number Summary Calculator

### Input Your Data:

Start by entering your dataset as comma-separated values into the calculator. For instance, if your data points are 12, 7, 22, 18, and 5, input them as “12,7,22,18,5”.

### Sorting the Data:

The calculator automatically sorts your data in ascending order. Sorting is crucial because it allows the tool to determine the quartiles and median accurately. For example, the sorted dataset for the above values would be 5, 7, 12, 18, 22.

### Calculating Key Statistics:

**Minimum (Min):**This is the first value in your sorted dataset.**Maximum (Max):**This is the last value in your sorted dataset.**Median:**This is the middle value. If the number of data points is odd, it is the exact middle value. If even, it is the average of the two middle values. For the datasets 5, 7, 12, 18, and 22, the median is 12.**First Quartile (Q1):**This represents the median of the lower half of the dataset, not including the median if the dataset size is odd. For the lower half (5, 7), Q1 is 6.**Third Quartile (Q3):**This represents the median of the upper half, similar to Q1. For the upper half (18, 22), Q3 is 20.

### Additional Statistics:

**Mean (Average):**The calculator can also compute the mean, which is the sum of all data points divided by the number of points. For the dataset 5, 7, 12, 18, 22, the mean is (5 + 7 + 12 + 18 + 22) / 5 = 12.8.**Count:**This is simply the total number of data points in your dataset.**Sum:**The total of all data points combined.
