Printing for a group?
The batch download puts all 2 tiers' August 2018 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in August 2018
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 2018A card is drawn at random from a normal 52-card pack. Find P(drawing a King or a Queen).
- 2nd August 2018A histogram for exam scores has bars of equal width 10 marks, covering 0-10, 10-20, 20-30, 30-40, with heights 2, 8, 15, 5. How many students took the exam?
- 3rd August 2018Name the five values needed to draw a box plot.
- 4th August 2018Give one reason you might choose to keep an outlier in a data set rather than remove it.
- 5th August 2018A region records 90 crimes in a population of 45,000. Find the crude crime rate per 1000 people.
- 6th August 2018A 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?
- 7th August 2018A 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.
- 8th August 2018Class A has a mean test score of 62 and Class B has a mean of 58. Which class did better on average?
- 9th August 2018A rent index shows 2019 = 100 and 2024 = 118. Find the actual rent in 2024 if the 2019 rent was 650 pounds.
- 10th August 2018A fair coin is flipped once. What is P(heads)?
- 11th August 2018Student 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?
- 12th August 2018A coin is flipped twice. Find the probability of getting two heads.
- 13th August 2018A pyramid is roughly the same width all the way up, with only a slightly narrower top. What does this suggest?
- 14th August 2018A distribution has mean = mode = median. What does this suggest about its shape?
- 15th August 2018A 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.
- 16th August 2018A set of 7 numbers has a mean of 12. Find the total of all 7 numbers.
- 17th August 2018A population has 200 members and a sample of 20 is needed using systematic sampling. Find the sampling interval.
- 18th August 2018What is meant by the independent variable in an experiment?
- 19th August 2018Why must class intervals in a grouped frequency table not overlap?
- 20th August 2018Chart 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?
- 21st August 2018Using the pupils in the previous question, find P(likes football only).
- 22nd August 2018A line of best fit passes through the points (0, 4) and (10, 24). Find its gradient.
- 23rd August 2018What word describes a situation where one variable directly causes a change in another?
- 24th August 2018The 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.
- 25th August 2018Give one reason a researcher would carry out a pilot survey.
- 26th August 2018Is 'favourite ice cream flavour' qualitative or quantitative data?
- 27th August 2018Group A has 10 items with mean 50. Group B has 5 items with mean 80. Find the combined mean.

- 29th August 2018A composite bar for Year 7 shows Boys 20 stacked below Girls, with a total bar height of 45. How many girls are there?
- 30th August 2018A 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?
- 31st August 2018On a cumulative frequency graph, what do you plot each cumulative frequency against?
