Histograms represent the distribution of numerical data. Learn how to interpret and solve Math problems containing histograms.

## Step by step guide to solve Histograms problems

- A histogram is an accurate representation of the distribution of numerical data.
- Histogram groups numbers into
**ranges**and is similar to bar charts. - To interpret histograms, check the height of each bar that shows how many fall into each range.

### Example 1:

Use the following Graph to complete the table.

**Solution:** Check the distance during each day from the graph and write it in the table below. For example, the distance for day 1 is 378 and for day 2 is 480.

Day | Distance (km) |

1 | 378 |

2 | 480 |

3 | 285 |

4 | 536 |

5 | 370 |

### Example 2:

Use the following Graph to complete the table.

**Solution:** Check the distance during each day from the graph and write it in the table below.

Day | Distance (km) |

1 | 359 |

2 | 460 |

3 | 278 |

4 | 547 |

5 | 360 |

## Exercises
