MCA Math Vocabulary 4th Grade Practice Test

A graph with bars to display data is called a bar graph. The height or length of each bar shows a value, making it easy to compare different categories at a glance. Bars can be vertical or horizontal. For example, you could compare how many students prefer each fruit by showing a bar for apples, a bar for bananas, and a bar for cherries. The other options serve different purposes: a line chart uses connected points to show changes over time, a histogram shows how data are distributed across ranges, and a pie chart displays parts of a whole as slices.
