Printing for a group?
The batch download puts all 2 tiers' June 2024 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in June 2024
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 2024A school of 600 students wants a sample of 30. A teacher decides to only survey students in her own class of 30. State one problem with this method.
- 2nd June 2024A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 3rd June 2024The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 4th June 2024In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 5th June 2024A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 6th June 2024A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 7th June 2024A 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.
- 8th June 2024Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 9th June 2024What is a pilot survey?
- 10th June 2024Is 'height of a plant in cm' discrete or continuous data?
- 11th June 2024Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
- 12th June 2024Using the survey in the previous question (Red 6, Blue 9, Green 4, Yellow 5), which colour is the mode?
- 13th June 2024A 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?
- 14th June 2024A 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.
- 15th June 2024A frequency table has class frequencies 5, 9, 14, 7 for four consecutive classes. Find the cumulative frequency of the third class.
- 16th June 2024A 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?
- 17th June 2024In 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?
- 18th June 2024Data 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.
- 19th June 2024Which stage of the statistical enquiry cycle comes immediately after collecting the data?
- 20th June 2024A student uses figures from a government website for her project. Is this primary or secondary data?
- 21st June 2024Find the median of: 3, 5, 8, 10.
- 22nd June 2024Two 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.
- 23rd June 2024Using two fair six-sided dice added together, find P(total is 7).
- 24th June 2024Two 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?
- 25th June 2024A time series graph generally slopes upward from left to right over several years. What is this called?
- 26th June 2024Out 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.
- 27th June 2024In a survey of 40 students, 25 like Maths. Of those 25, 18 also like Science. Find P(likes Science given likes Maths).
- 28th June 2024A bar chart's vertical axis runs from 0 to 10 in equal steps of 2. Is this axis likely to be misleading?
- 29th June 2024The 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.
- 30th June 2024Give one reason why the response options '0-5, 5-10, 10-15' are a poor choice for hours of homework.
