Question

Find the mean of the following, 1.5 m,1.7 m,1.6 m,1.5m,1.5m.​

Answer 1

We can find the mean of these numbers by adding all of them, and then dividing by the amount of numbers added. Firstly, we need to add 1.5m + 1.7m + 1.6m + 1.5m + 1.5m to give us 7.8m. We added 5 numbers, so we will now divide by 5. This gives us 1.56m.
