Tally - GCSE Maths Definition

Reviewed by: Dan Finlay

Published

A tally is a way of counting how many times something happens during an event, whilst that event is in progress. For example, we could use a tally to count the number of red, silver and black cars passing the front of the school between 1pm, and 2pm. Each count on a tally is a short vertical line, and they are grouped into blocks of five, by having the fifth tally mark as a (diagonal) line passing through the others.

At the end of the event, a tally gives a visual, quick and easy way to total up how many times something happened.
