Statistics, worked out

The Dot Plot

What’s typical, and how spread out? Find the mean, median, mode and range, draw a dot plot, a box plot or a histogram to scale, read a frequency table, measure the spread, and work back to a missing number — with the reason for every step.

The work

Say it out loud

    Up to 60 numbers, worked out exactly — a mean that doesn’t come out even is shown as a fraction and a decimal. Need a long division done out? Work it on ÷, or turn a fraction into a decimal on ½.
