Math Topic 15 - Data and Graphing

Data is information collected about something, like numbers or facts.

A graph is a picture that shows data in a way that is easy to understand.

To compare data means to look at two or more sets of information to see how they are different or similar.

A bar graph uses bars to show how much of something there is.

A line graph uses points connected by lines to show how something changes over time.

A tally chart is a way to count things using marks.

To find the total, you add all the numbers together.

'Fewest' means the smallest number in a group.

'Most' means the largest number in a group.

To read a graph, look at the labels and see what the bars or lines represent.
