# 7-day average

A 7-day average is the mean of the last seven days of a number, recalculated each day, so one odd day moves the line only a little.

It smooths daily noise in measures such as body weight, steps or resting heart rate. Body weight, for example, follows a weekly rhythm in many adults, so a single morning reading says little. Read the direction of the average over two to four weeks, not any one day.

Also called: Rolling average, Moving average.
