Graphs, charts and tables are used to represent data (information) and make it easier to understand. ## Interpreting Data

Data means **information**. So interpreting data just means working out what the information is telling you. Information is sometimes shown in **tables, charts and graphs** to make the information easier to read. It is important to read all the different parts of the table, chart or graph.

## Tables

A table is used to write down a number of pieces of data about different things.

The **title** of the table tells us what the table is about.

The **headings** tell us what data is in each column.

## Tally Charts

Tally marks are used for **counting** things. They are small vertical lines (like the number 1) each one representing one unit. The 5th tally mark in a group is always drawn across the first four - as this makes it easier to count the total in groups of five.

## Bar Charts

Bar charts are one way of showing the information from a frequency table. This bar chart represents the data from the table above:

## Pictograms

## Pie Charts

## Line Graphs
