Chapter 1 Data Collection
1.1 Populations and Samples
In statistics, a population is the whole set of items that are of interest. For example, the population could be the items manufactured by a factory or all the people in a town. Information can be obtained from a population. This is known as raw data. sample is a selection of observations taken from a subset of the population which is used to find out information about the population as a whole.
If you're a student in a school/college that's based in England, you might be entitled for full access to our eLearning platform where you can access to all our tutorial videos and practice questions.
Please check with the head of Maths or deputy headteacher at your school/college to request access if they've already registered to our free pilot subscription. They can always reach us at the below email:
