## 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.

### Histograms – 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 | 436 |

5 | 370 |

### Histograms – 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 for Solving Histograms

### The following table shows the number of births in the US from \(2007\) to \(2012\) (in millions).

Answer these questions based on the data of the graph.

1- During what period the percent of change was zero?

2- During what period there was the biggest decrease in the number of births?

3- What was the percent of change from \(2008\) to \(2012\)?
