Printing for a group?
The batch download puts all 2 tiers' May 2004 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in May 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 2004On a population pyramid, which axis shows the age groups?
- 2nd May 2004A box plot shows a long whisker on the left and a short whisker on the right, with the median close to the right of the box. What type of skew does this suggest?
- 3rd May 2004A survey of 30 shoppers out of 900 in a store found the mean amount spent was 18.50 pounds. What is the best estimate of the mean amount spent by all 900 shoppers?
- 4th May 2004Find the median of 8, 3, 15, 3, 10.
- 5th May 2004A 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.
- 6th May 2004A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 7th May 2004The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 8th May 2004In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 9th May 2004A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 10th May 2004A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 11th May 2004A 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.
- 12th May 2004Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 13th May 2004What is a pilot survey?
- 14th May 2004Is 'height of a plant in cm' discrete or continuous data?
- 15th May 2004Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
- 16th May 2004Using the survey in the previous question (Red 6, Blue 9, Green 4, Yellow 5), which colour is the mode?
- 17th May 2004A 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?
- 18th May 2004A 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.
- 19th May 2004A frequency table has class frequencies 5, 9, 14, 7 for four consecutive classes. Find the cumulative frequency of the third class.
- 20th May 2004A 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?
- 21st May 2004In 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?
- 22nd May 2004Data 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.

- 26th May 2004Two 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.
- 27th May 2004Using two fair six-sided dice added together, find P(total is 7).
- 28th May 2004Two 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?
- 29th May 2004A time series graph generally slopes upward from left to right over several years. What is this called?

- 31st May 2004In a survey of 40 students, 25 like Maths. Of those 25, 18 also like Science. Find P(likes Science given likes Maths).
