Create and interpret histograms

Interactive practice questions

Examine the histogram given and answer the following questions.

A bar graph with the horizontal axis represents the scores, and the vertical axis represents the frequency. The Score axis is marked with numbers from 0 to 4. The Frequency axis has intervals marked from 0 to 30 at an increment of 2, with major ticks labeled at 10, 20 and 30. Each bar tells how frequent the score occurs by how tall the bar is.

Which number occured most frequently?
