Our Christmas Quiz for 2024 was a smash hit, with more entrants than ever!
Last year’s edition of the Christmas Quiz, published with the Royal Statistical Society, featured a warm up round alongside the fiendish puzzles of years gone by. We’re now very pleased to share the answers and solutions to both with you.
How closely were you paying attention to the biggest statistics of 2024?
Section A: 1) c) 27. 2) c) Vinyl records. 3) a) Latvia. 4) b) Madonna. 5) a) 122.8 kilometres. 6) a) 38.8%. 7) b) 50%. 8) d) 37%. 9) a) Niger. 10) a) The total distance travelled is two kilometres. The total time taken is 3 minutes + 2 minutes = 5 minutes. Average speed is 24 km/hr. 24 is the harmonic mean of 20 and 30. b) The geometric mean of 9 and 16 is the square root of 9×16. c) The most common shoe size is 8½. The average being used is the mode. d) 50% of the population receive at least £24500. The average being used is the median. e) It is the total weight in the lift that is important. The average being used is the arithmetic mean. 11) The numbers on the dice are 1335 and 1223. 12) Probability not born under the same star sign = 11/12 x 10/12 x 9/12 x 8/12 x 7/12 = 0.223. Hence, probability at least two are born under the same star sign = 0.777.
