Printing for a group?
The batch download puts all 2 tiers' January 2004 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in January 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st January 2004In a data set of 200 values, at what position, counting from the smallest, would you expect to find the 25th percentile?

- 13th January 2004The table shows weights, in kg, of 20 parcels: 0-5 (freq 4), 5-10 (freq 10), 10-15 (freq 6). Estimate the mean weight.

- 16th January 2004A game has four mutually exclusive outcomes: win, draw, lose, abandoned. P(win) = 0.45, P(draw) = 0.2, P(abandoned) = 0.05. Find P(lose).

- 18th January 2004Box plot A has a median of 50 and box plot B has a median of 42, for the same type of data. What does this tell you about the two data sets?

- 22nd January 2004Using the same table (0:4, 1:10, 2:4, 3:2), find the median number of siblings.
- 23rd January 2004Data set X has a range of 12 and data set Y has a range of 5. Which data set is more consistent?
- 24th January 2004An index number is 140 with a base value of 20. Find this year's value.
- 25th January 2004A bag has 4 yellow and 6 white balls. What is P(picking a yellow ball)?
