# What does standard deviation show on a graph?

## What does standard deviation show on a graph?

The bell **curve** or **standard deviation graph** is used to visualise the spread of data. Excel is powerful tool to create **graphs** and visualise data and it can be used to create the bell **graph**. The **standard deviation** tells how much the data is clustered around the mean of the data.

## Which graph has a higher standard deviation?

The standard deviation is a measure of how far points are from the **mean**. The first histogram has more points farther from the **mean** (scores of 0, 1, 9 and 10) and fewer points close to the **mean** (scores of 4, 5 and 6). So it will have the larger standard deviation.

## How do you conclude a standard deviation?

Basically, a small **standard deviation** means that the values in a statistical data set are close to the mean of the data set, on average, and a large **standard deviation** means that the values in the data set are farther away from the mean, on average.

## What is a reliable standard deviation?

A high **standard deviation** shows that the data is widely spread (less **reliable**) and a low **standard deviation** shows that the data are clustered closely around the mean (more **reliable**).
