Decimal - GCSE Psychology Definition

Reviewed by: Raj Bonsor

Published

Decimal numbers are a way of showing parts of a whole, using a dot called a decimal point.

In GCSE Psychology, decimals might be used when you look at results from experiments or surveys, because you might not always get whole numbers. For example, if you measure how many hours a group of people sleep, your result might be 7.5 hours instead of just 7 or 8 hours.

Decimals help us to be more precise when we measure or calculate things, making it easier to compare and analyse data in psychology experiments.
