Data and Graphing

A frequency table is a way to organize data that shows how often each item occurs.

A bar graph represents data with rectangular bars, where the length of each bar is proportional to the value it represents.

A pie chart shows parts of a whole, with each slice representing a category's proportion of the total.

A key explains what the symbols or colors in a graph represent.

Look for the tallest bar or the largest point on the graph to see which month has the most money saved.

It means that the value represented by the longer bar is twice as much as the value of the shorter bar.

Count the total number of pictures or symbols, and multiply by the value each picture represents.

A pictogram is a graph that uses pictures or symbols to represent data.

It means that no data or items were recorded for that category.

Look at the heights of the bars to see which category has a greater value.
