Printing for a group?
The batch download puts all 2 tiers' February 2026 sheets in a single PDF, each tier behind its own divider page - 56 sheets in one file.
Every sheet in February 2026
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st February 2026Find the range of 22, 9, 31, 14, 6, 27.
- 2nd February 2026A gym has 900 members. A sample of 45 is needed using systematic sampling, with a random start of 12. Find the 4th person selected.
- 3rd February 2026In a medicine trial, half the patients receive the real drug and half receive a dummy pill, and neither the patients nor the doctors know who received which until after results are recorded. What is this type of trial called, and why is it used?
- 4th February 2026Using the data in the previous question (12, 18, 25, 31, 9, 22, 15), state the frequency of the interval 20 <= x < 30.
- 5th February 2026A sector has an angle of 72 degrees in a pie chart representing 50 people in total. How many people does this sector represent?
- 6th February 2026In a Venn diagram, what does the region where two circles overlap represent?
- 7th February 2026A scatter graph shows points that generally fall from top left to bottom right. What type of correlation does this show?
- 8th February 2026A study finds a positive correlation between shoe size and reading ability in primary school children. Does having big feet cause better reading?
- 9th February 2026A researcher finds rs = 0.99 between a town's number of ice cream vans and its number of sunburn cases, and concludes the vans cause sunburn. Explain why this conclusion may be wrong.
- 10th February 2026A tick-box question has the options '0-10', '10-20', '20-30'. What problem would a pilot survey likely identify with this?
- 11th February 2026Is 'number of pets owned' discrete or continuous data?
- 12th February 2026Group A has 6 items with mean 15. Group B has 9 items with mean 25. Find the combined mean.
- 13th February 2026A frequency table for test scores out of 10 shows: score 6 has frequency 5, score 7 has frequency 8, score 8 has frequency x, score 9 has frequency 3, and the total frequency is 25. Find x.
- 14th February 2026Two composite bars compare tea and coffee drinkers: Monday has a total of 60 drinks, of which 35 are tea; Tuesday has a total of 72 drinks, of which 40 are tea. On which day was a greater proportion of drinks tea?
- 15th February 2026A stem-and-leaf diagram has the row '1 | 4 7 9' with key '1|4 means 14'. What three data values does this row represent?
- 16th February 2026Explain why a value read from a cumulative frequency graph, such as the median, is described as an estimate rather than an exact value.
- 17th February 2026On a choropleth map shaded from white (lowest) to black (highest), a region is coloured mid-grey. What does this suggest about its value?
- 18th February 2026A cumulative frequency graph shows that a value of 18 corresponds to a cumulative frequency of 45 out of 60 total data points. Find the percentile.
