Printing for a group?
The batch download puts all 2 tiers' April 2004 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in April 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st April 2004A stem-and-leaf diagram has rows: 0|5 8, 1|2 2 6, 2|1. How many data values are there in total?
- 2nd April 2004For 80 data values, at what cumulative frequency do you read across to find the lower quartile?
- 3rd April 2004Two neighbouring regions on a choropleth map are shaded the same colour. What can you conclude about their values?
- 4th April 2004Which percentile is the same as the median?
- 5th April 2004A spreadsheet shows the formula =SUM(F1:F5)/COUNT(F1:F5) in cell F6. What statistical measure does this formula calculate?
- 6th April 2004State two things that should be decided during the planning stage of the enquiry cycle.
- 7th April 2004State whether interviewing shoppers face-to-face about their favourite supermarket is primary or secondary data collection.
- 8th April 2004For the ordered data 6, 9, 11, 14, 16, 18, 20, 23, 25, 28, find the interquartile range.
- 9th April 2004A 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?
- 10th April 2004A 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)?
- 11th April 2004A class interval is 20-30 with frequency 8. Give the coordinates of the point plotted for this class.
- 12th April 2004A time series shows sales peaking every December for five years in a row. What is this repeating pattern called?
- 13th April 2004Express a risk of 1/20 as a percentage.
- 14th April 2004A 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).
- 15th April 2004A 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?
- 16th April 2004Find the midpoint of the class interval 10-20.
- 17th April 2004A survey question offers the response options 'Never, Sometimes, Always'. State one improvement that could be made.
- 18th April 2004Find the 3-point moving average of 10, 14, 18.
- 19th April 2004A bag has only red, blue and green counters. P(red) = 0.5 and P(blue) = 0.2. Find P(green).
- 20th April 2004A histogram has bars of equal width. True or false: the height of each bar represents the frequency for that class.
- 21st April 2004A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 22nd April 2004A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 23rd April 2004A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 24th April 2004A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 25th April 2004Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 26th April 2004Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 27th April 2004An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 28th April 2004An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 29th April 2004Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 30th April 2004A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
