We all use and generate data on a daily basis. For example, companies use data to track our shopping and offer us deals. Data has become very important.

There are many different types of data. Continuous data is something you measure, like, the length of a piece of wood. A box of nails is usually something you can count, which is called discrete data.

Different ways of displaying data include using graphs. A line graph can show the relationship between some data about a shelf. A pie chart can show the ways that someone spends their time, which is easy to see and understand as a picture.

Gathering data can help to work out different types of average-- like the range, which is the difference between the lowest and highest values. Or the median, which is basically, the middle.

Data can even be used to work out probability – how likely are unlikely something is to happen, which can help you avoid unpleasant surprises.
