# How to Interpret Histogram 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.

### 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 $$480$$.

### 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.

## 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 $$2012$$?

1- $$\color{blue}{2011- 2012}$$

2- $$\color{blue}{2009 – 2010}$$

3- $$\color{blue}{7\% }$$ #### Effortless Math Educations
