Printing for a group?
The batch download puts all 2 tiers' June 2001 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in June 2001
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 2001Two 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?
- 2nd June 2001A 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?
- 3rd June 2001Explain why a value read from a cumulative frequency graph, such as the median, is described as an estimate rather than an exact value.
- 4th June 2001On a choropleth map shaded from white (lowest) to black (highest), a region is coloured mid-grey. What does this suggest about its value?
- 5th June 2001A 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.
- 6th June 2001A column of 8 test scores is in cells D2 to D9. Give the formula for the mean score.
- 7th June 2001Name the first stage of the statistical enquiry cycle.
- 8th June 2001State one advantage secondary data has over primary data for a project on rainfall over the last 50 years.
- 9th June 2001A data set has Q1 = 22 and Q3 = 35. State the interquartile range and explain what it measures.
- 10th June 2001A pictogram key shows 1 symbol = 4 books. A row has 2 and a half symbols. How many books does the row represent?
- 11th June 2001Two fair coins are flipped. How many equally likely outcomes are in the sample space?
- 12th June 2001A frequency table has classes 0-10, 10-20, 20-30 with frequencies 3, 9, 6. State all three coordinates for the frequency polygon.
- 13th June 2001On a time series graph, what is always plotted on the horizontal axis?
- 14th June 2001Group A has a risk of 0.08 of an event happening; Group B has a risk of 0.02. Find the relative risk of Group A compared with Group B.
- 15th June 2001A bag has 3 red, 4 green and 5 blue balls (12 total). One ball is removed at random and is blue. A second ball is then removed. Find P(second ball is red given the first ball was blue).
- 16th June 2001A 3D pie chart is used to show market share. Explain why 3D charts can be misleading.
- 17th June 2001A table has class intervals with frequency x midpoint totals of 45, 120, 90 and frequencies 5, 8, 6. Find the estimated mean.
- 18th June 2001Explain why a pilot survey should be carried out before the full survey is sent out.
- 19th June 2001Find the 4-point moving average of 12, 16, 20, 10.
- 20th June 2001P(rain) = 0.3 and P(snow) = 0.05 on a given day, and rain and snow are mutually exclusive that day. Find P(rain or snow).
- 21st June 2001Using the same histogram, how many students scored between 10 and 30 marks?
- 22nd June 2001A box plot has lower quartile 10 and upper quartile 22. Find the interquartile range.
- 23rd June 2001The heights (cm) of 6 plants are: 15, 18, 16, 14, 17, 150. Find the mean of the remaining values after removing the outlier.
- 24th June 2001Explain why a crude rate is more useful than a raw total, such as the total number of deaths, when comparing two towns of different sizes.
- 25th June 2001A factory has 400 workers: 160 in production, 120 in packing and 120 in admin. A stratified sample of 50 workers is needed. Find how many should be sampled from packing.
- 26th June 2001Using the same table (0:4, 1:10, 2:4, 3:2), find the mean number of siblings.
- 27th June 2001The mean rainfall in April was 45 mm with a range of 20 mm; in May it was 45 mm with a range of 8 mm. Compare April and May.
- 28th June 2001A cost index for electricity, relative to the same base year, was 120 in 2021 and 150 in 2023. Find the percentage increase in the cost of electricity from 2021 to 2023 (not from the base year).
- 29th June 2001The probability that a train is late is 0.15. Out of 200 trains, how many would you expect to be late?
- 30th June 2001The probability that a machine produces a faulty item is 0.04. Out of 300 items, how many would you expect to be faulty?
