Printing for a group?
The batch download puts all 2 tiers' November 2016 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in November 2016
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2016In a Venn diagram, what does the region where two circles overlap represent?
- 2nd November 2016A scatter graph shows points that generally fall from top left to bottom right. What type of correlation does this show?
- 3rd November 2016A study finds a positive correlation between shoe size and reading ability in primary school children. Does having big feet cause better reading?
- 4th November 2016A 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.
- 5th November 2016A tick-box question has the options '0-10', '10-20', '20-30'. What problem would a pilot survey likely identify with this?
- 6th November 2016Is 'number of pets owned' discrete or continuous data?
- 7th November 2016Group A has 6 items with mean 15. Group B has 9 items with mean 25. Find the combined mean.
- 8th November 2016A 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.
- 9th November 2016Two 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?
- 10th November 2016A 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?
- 11th November 2016Explain why a value read from a cumulative frequency graph, such as the median, is described as an estimate rather than an exact value.
- 12th November 2016On a choropleth map shaded from white (lowest) to black (highest), a region is coloured mid-grey. What does this suggest about its value?
- 13th November 2016A 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.
- 14th November 2016A column of 8 test scores is in cells D2 to D9. Give the formula for the mean score.
- 15th November 2016Name the first stage of the statistical enquiry cycle.
- 16th November 2016State one advantage secondary data has over primary data for a project on rainfall over the last 50 years.

- 18th November 2016A pictogram key shows 1 symbol = 4 books. A row has 2 and a half symbols. How many books does the row represent?
- 19th November 2016Two fair coins are flipped. How many equally likely outcomes are in the sample space?
- 20th November 2016A frequency table has classes 0-10, 10-20, 20-30 with frequencies 3, 9, 6. State all three coordinates for the frequency polygon.
- 21st November 2016On a time series graph, what is always plotted on the horizontal axis?
- 22nd November 2016Group 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.
- 23rd November 2016A 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).
- 24th November 2016A 3D pie chart is used to show market share. Explain why 3D charts can be misleading.
- 25th November 2016A table has class intervals with frequency x midpoint totals of 45, 120, 90 and frequencies 5, 8, 6. Find the estimated mean.
- 26th November 2016Explain why a pilot survey should be carried out before the full survey is sent out.
- 27th November 2016Find the 4-point moving average of 12, 16, 20, 10.
- 28th November 2016P(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).

- 30th November 2016A box plot has lower quartile 10 and upper quartile 22. Find the interquartile range.
