  • Why do we collect data?

    Data are a collection of unorganised observations and can contain thousands of entries. We collect data to gain information and solve a problem or make informed decisions. In order to make sense of the data we need to condense it or organise it in a way that makes interpretation easier. 

    Data is used to calculate statistics, which help you understand what the data collected is all about. Data collection is very important for many businesses to make sure they are operating optimally. 

    Before you learn about organising, representing and summarising data, it is important that you understand the different types of data.
