GCSE Maths Practice: bar-charts

Question 2 of 10

Identify which bar deviates most from the mean.

‹ ›

\( \begin{array}{l}\text{A bar chart shows sales of 5 products: 10, 8, 12, 7, 13.} \\ \text{Which product's sales deviate the most from the mean?}\end{array} \)

Choose one option:

\( \text{Product 5} \) \( \text{Product 4} \) \( \text{Product 2} \)

Calculate mean first, then deviations.

Deviation = |value - mean|.
