  • 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)
1378
2480
3285
4536
5370

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)
1359
2460
3278
