The question, in short

For eight listed weekly wages, find the middle value and explain why the arithmetic average might misrepresent the group.

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

Part (a) · 2 marks

Calculate the median of the eight given wage amounts.

  1. 1Order: 210, 220, 230, 235, 245, 245, 265, 850
  2. 2Middle two values are 235 and 245
  3. 3Median = (235 + 245) ÷ 2 = 240

Answer240

Part (b) · 1 mark

State why the mean could be an unsuitable representative average for these wages.

  1. 1$850 is an extreme value (outlier), much larger than the others
  2. 2It pulls the mean up so the mean is not typical of most wages

Answer850 is much larger than the other values, which affects the mean
