Turning coins Aim: Investigate the factors affecting the number of 2p coins that can be turned over in 10 seconds. Objective: To have an opportunity to compare data and calculate mean, median, mode and range of the data collected. Year 6

Turning coins Place 10 2 pence coins in a row along the edge of a table, with approximately a finger’s space between them.

Turning coins Work in a group of 2 or 3, one timing 10 seconds, one keeping count and one turning.

Turning coins Turn the coins one by one, with the fastest hand from Year 5 first. Make sure that you go back to the start of the row after turning ten coins, and don’t work your way back.

Turning coins What about a practice turn first ?

Turning coins Don’t forget to record your results on your personal worksheet.

Turning coins Now you need to find the mean, median, mode and range of the number of the coins turned over. 20, 26, 26, 21, 19, 24, 25, 26, 20, 22, 25, 21, 18, 22, 24, 21, 19, 27, 28, 26 18, 19, 19, 20, 20, 21, 21, 21, 22, 22, 24, 24, 25, 25, 26, 26, 26, 26, 27, 28 Mean 460 ÷ 20 = 23 Median = 23 2 Mode 26 Range 28 – 18 = 10
