Printing for a group?
The batch download puts all 2 tiers' April 2018 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in April 2018
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st April 2018In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 2nd April 2018A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 3rd April 2018A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 4th April 2018A researcher finds that towns with more fire engines have more fire damage, and concludes that fire engines cause fire damage. Identify the flaw in this reasoning and suggest the true common cause.
- 5th April 2018Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 6th April 2018What is a pilot survey?
- 7th April 2018Is 'height of a plant in cm' discrete or continuous data?
- 8th April 2018Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
- 9th April 2018Using the survey in the previous question (Red 6, Blue 9, Green 4, Yellow 5), which colour is the mode?
- 10th April 2018A bar chart uses a scale where each small square represents 2 people. A bar is 7 squares tall. How many people does the bar represent?
- 11th April 2018A stem-and-leaf row, with key '3|1 means 31', is '3|0 2 4 4 7 9'. Find the median of these six values.
- 12th April 2018A frequency table has class frequencies 5, 9, 14, 7 for four consecutive classes. Find the cumulative frequency of the third class.
- 13th April 2018A choropleth map of rainfall uses two different hues (for example yellow to red) rather than one hue getting darker. Why can this style of shading be a problem?
- 14th April 2018In a class of 30 students, a student's mark is at the 90th percentile. Roughly how many students scored less than or equal to that mark?
- 15th April 2018Data on 200 students' exam scores is in a spreadsheet. Give one advantage of using a spreadsheet rather than calculating the mean and range by hand.
- 16th April 2018Which stage of the statistical enquiry cycle comes immediately after collecting the data?
- 17th April 2018A student uses figures from a government website for her project. Is this primary or secondary data?

- 19th April 2018Two rows of a pictogram show 4.5 symbols and 3.5 symbols, with a key of 1 symbol = 20 pounds. Work out the combined total for both rows.
- 20th April 2018Using two fair six-sided dice added together, find P(total is 7).
- 21st April 2018Two frequency polygons are drawn on the same axes for boys' and girls' test scores. What feature of the graphs shows which group generally scored higher?
- 22nd April 2018A time series graph generally slopes upward from left to right over several years. What is this called?
- 23rd April 2018Out of 600 drivers who used a phone while driving, 24 had an accident that year, compared with 9 out of 900 drivers who did not use a phone. Calculate the risk of an accident for each group.
- 24th April 2018In a survey of 40 students, 25 like Maths. Of those 25, 18 also like Science. Find P(likes Science given likes Maths).
- 25th April 2018A bar chart's vertical axis runs from 0 to 10 in equal steps of 2. Is this axis likely to be misleading?
- 26th April 2018The table shows ages, in years, of 50 people at a gym: 10-20 (freq 6), 20-30 (freq 18), 30-40 (freq 16), 40-50 (freq 10). Estimate the mean age.
- 27th April 2018Give one reason why the response options '0-5, 5-10, 10-15' are a poor choice for hours of homework.
- 28th April 2018Find the 4-point moving average of 8, 12, 16, 20.
- 29th April 2018Are 'rolling an even number' and 'rolling a 5' on a normal six-sided dice mutually exclusive?
- 30th April 2018A histogram of ages has 5 equal-width bars covering 0-10, 10-20, 20-30, 30-40, 40-50 with heights 3, 7, x, 9, 2, and a total of 35 people. Find x.
