Every sheet in July 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st July 1996A grouped frequency table has intervals of unequal width, 0 <= x < 10 and 10 <= x < 40. Explain why this could make the table misleading when drawing a histogram.
- 2nd July 1996A pie chart represents 200 people. One sector has an angle of 45 degrees. How many people does it represent?
- 3rd July 1996Out of 25 pupils, 12 like football, 9 like tennis, and 4 like both. How many like neither sport?
- 4th July 1996A scatter graph shows points that generally rise from bottom left to top right. What type of correlation does this show?
- 5th July 1996A scatter graph shows that as temperature increases, the number of hot drinks sold decreases. What type of correlation is this?
- 6th July 1996For a class, the Spearman's rank correlation coefficient between shoe size and spelling test score is rs = 0.15. Describe the correlation.
- 7th July 1996A company pilots its customer feedback survey on 20 customers before sending it to all 5000 customers. Explain why using only 20 people is still useful.

- 12th July 1996A stem-and-leaf diagram has rows: 0|5 8, 1|2 2 6, 2|1. How many data values are there in total?
- 13th July 1996For 80 data values, at what cumulative frequency do you read across to find the lower quartile?
- 14th July 1996Two neighbouring regions on a choropleth map are shaded the same colour. What can you conclude about their values?
- 15th July 1996Which percentile is the same as the median?
- 16th July 1996A spreadsheet shows the formula =SUM(F1:F5)/COUNT(F1:F5) in cell F6. What statistical measure does this formula calculate?
- 17th July 1996State two things that should be decided during the planning stage of the enquiry cycle.
- 18th July 1996State whether interviewing shoppers face-to-face about their favourite supermarket is primary or secondary data collection.

- 20th July 1996A pictogram key shows 1 symbol = 6 cakes. A row has 1 symbol and a third of a symbol. How many cakes does the row represent?
- 21st July 1996A spinner with sections A, B and C is spun alongside a fair coin. How many outcomes are in the sample space, and what is P(getting C and Heads)?
- 22nd July 1996A class interval is 20-30 with frequency 8. Give the coordinates of the point plotted for this class.
- 23rd July 1996A time series shows sales peaking every December for five years in a row. What is this repeating pattern called?
- 24th July 1996Express a risk of 1/20 as a percentage.
- 25th July 1996A box has 4 chocolate and 6 plain biscuits. One biscuit is eaten (it was chocolate), then a second is taken at random. Find P(second is chocolate given first was chocolate).
- 26th July 1996A pictogram uses one whole apple symbol to represent 10 apples sold, but one row shows a half apple symbol with no key given for partial symbols. Why could this be misleading?
