Printing for a group?
The batch download puts all 2 tiers' January 2024 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in January 2024
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st January 2024A youth club has 45 members under 13 and 75 members aged 13 to 17 (120 total). A stratified sample of 40 members is needed. How many aged 13 to 17 should be sampled?
- 2nd January 2024A different table shows test scores out of 5 for 30 students: 1 (freq 3), 2 (freq 5), 3 (freq 9), 4 (freq 8), 5 (freq 5). Find the mean score.
- 3rd January 2024Class A has a mean test score of 62 and Class B has a mean of 58. Which class did better on average?
- 4th January 2024A rent index shows 2019 = 100 and 2024 = 118. Find the actual rent in 2024 if the 2019 rent was 650 pounds.
- 5th January 2024A fair coin is flipped once. What is P(heads)?
- 6th January 2024Student A rolls a dice 20 times and gets a 6 four times. Student B rolls the same dice 300 times and gets a 6 forty-eight times. Whose relative frequency is a more reliable estimate of the true probability, and what is it?
- 7th January 2024A coin is flipped twice. Find the probability of getting two heads.
- 8th January 2024A pyramid is roughly the same width all the way up, with only a slightly narrower top. What does this suggest?
- 9th January 2024A distribution has mean = mode = median. What does this suggest about its shape?
- 10th January 2024A garden centre sampled 45 out of 3000 trees and found 40 had survived the winter. Estimate how many of the 3000 trees survived the winter.
- 11th January 2024A set of 7 numbers has a mean of 12. Find the total of all 7 numbers.
- 12th January 2024A population has 200 members and a sample of 20 is needed using systematic sampling. Find the sampling interval.
- 13th January 2024What is meant by the independent variable in an experiment?
- 14th January 2024Why must class intervals in a grouped frequency table not overlap?
- 15th January 2024Chart A represents 80 votes and has a 'Green Party' sector of 45 degrees. Chart B represents 150 votes and has a 'Green Party' sector of 30 degrees. Which chart represents more actual Green Party votes?
- 16th January 2024Using the pupils in the previous question, find P(likes football only).
- 17th January 2024A line of best fit passes through the points (0, 4) and (10, 24). Find its gradient.

- 19th January 2024The Spearman's rank correlation coefficient between hours spent watching TV and test score is rs = -0.4. Describe the strength and direction of the correlation.
- 20th January 2024Give one reason a researcher would carry out a pilot survey.
- 21st January 2024Is 'favourite ice cream flavour' qualitative or quantitative data?
- 22nd January 2024Group A has 10 items with mean 50. Group B has 5 items with mean 80. Find the combined mean.

- 24th January 2024A composite bar for Year 7 shows Boys 20 stacked below Girls, with a total bar height of 45. How many girls are there?
- 25th January 2024A back-to-back stem-and-leaf diagram compares two classes' test scores. For stem 7, Class A (left side) has 3 leaves and Class B (right side) has 4 leaves. Which class had more students scoring in the 70s?
