Printing for a group?
The batch download puts all 2 tiers' May 1997 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in May 1997
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 1997A time series shows sales peaking every December for five years in a row. What is this repeating pattern called?
- 2nd May 1997Express a risk of 1/20 as a percentage.
- 3rd May 1997A 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).
- 4th May 1997A 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?
- 5th May 1997Find the midpoint of the class interval 10-20.
- 6th May 1997A survey question offers the response options 'Never, Sometimes, Always'. State one improvement that could be made.
- 7th May 1997Find the 3-point moving average of 10, 14, 18.
- 8th May 1997A bag has only red, blue and green counters. P(red) = 0.5 and P(blue) = 0.2. Find P(green).
- 9th May 1997A histogram has bars of equal width. True or false: the height of each bar represents the frequency for that class.
- 10th May 1997A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 11th May 1997A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 12th May 1997A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 13th May 1997A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 14th May 1997Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 15th May 1997Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 16th May 1997An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 17th May 1997An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 18th May 1997Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 19th May 1997A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
- 20th May 1997On a population pyramid, which axis shows the age groups?
- 21st May 1997A 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?
- 22nd May 1997A 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?
- 23rd May 1997Find the median of 8, 3, 15, 3, 10.
- 24th May 1997A 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.
- 25th May 1997A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 26th May 1997The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 27th May 1997In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 28th May 1997A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 29th May 1997A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 30th May 1997A 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.
- 31st May 1997Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
