Question 1 — Easy
River depth measurements at seven points (in metres): 1.2, 0.8, 2.4, 1.5, 0.9, 2.1, 1.8. What is the RANGE of these measurements?
Answer: Range = maximum − minimum = 2.4 − 0.8 = 1.6 m. Option A (2.4) gives the maximum value, not the range. Option C (1.53) approximates the mean: sum = 10.7, mean = 10.7 ÷ 7 ≈ 1.53. Option D (1.5) is the median: sorted data = 0.8, 0.9, 1.2, 1.5, 1.8, 2.1, 2.4 — the middle value is 1.5.
Question 2 — Medium
Two birdwatching groups recorded the number of native birds spotted each day for five days. Group 1: 4, 6, 6, 8, 6 Group 2: 3, 5, 7, 9, 11 Which statement correctly describes the distribution of Group 2 compared to Group 1?
Answer: Group 1's range is 8 − 4 = 4. Group 2's range is 11 − 3 = 8, so Group 2 is more spread out. In Group 2, every value is different, so there is no mode. Group 1's mode is 6 (appears three times). Option A incorrectly states Group 2 has a mode of 7. Option C incorrectly claims Group 1 is more spread out. Option D is wrong because the ranges differ.
Question 3 — Hard
A bag contains 5 red marbles, 4 blue marbles, and 3 green marbles. Mia picks one marble at random without looking. What is the probability that she picks a marble that is NOT red, expressed as a fraction in simplest form?
Answer: Total marbles = 12. Not-red marbles = 4 + 3 = 7. Probability = 7/12, which is already in simplest form.
