Ages: 10–20: 6 people, 20–30: 9 people, 30–40: 5 people. What is the greatest possible number aged 25 or over?

  1. 5
  2. 9
  3. 14
Show the answer

14

All 5 in the 30–40 class are over 25. All 9 in the 20–30 class could be 25 or over. So the greatest possible number is 9 + 5 = 14 (the least is 5).

In a survey of 30 students, 10 chose soccer. What angle is soccer's sector in a pie chart?

  1. 10°
  2. 36°
  3. 120°
Show the answer

120°

Angle = fraction × 360°. Soccer is 10/30 = 1/3 of the students, so 1/3 × 360° = 120°.

How are the bars of a histogram drawn?

  1. In order of height
  2. Touching, with no gaps
  3. With gaps between them
Show the answer

Touching, with no gaps

A histogram shows intervals of numerical data (0–10, 10–20 …) that run into each other, so the bars touch. A bar chart of categories has gaps.

Which of these is numerical data?

  1. Number of pets
  2. Favourite sport

Number of pets

Numerical data is a number you count or measure, like how many pets. Favourite sport and eye colour are labels, so they are categorical data.
