The question, in short

From a list of 12 midnight temperatures in °C, find the range and use the given median of 1 °C to determine the unknown value T.

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 1 mark

Find the range of the 12 recorded temperatures.

  1. 1Range = 7 − (−6) = 13

Answer13

Part (b) · 1 mark

Given the median is 1 °C, work out the value of T.

  1. 112 values: median = (6th + 7th) ÷ 2 = (−1 + T)/2 = 1
  2. 2−1 + T = 2 so T = 3
