Every sheet in February 2024
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

- 4th February 2024What value do you plot on the horizontal axis for each class of a frequency polygon?

- 12th February 2024A 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).
- 13th February 2024State one reason why a histogram has no gaps between its bars, unlike a bar chart.
- 14th February 2024Box 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?

- 18th February 2024Using the same table (0:4, 1:10, 2:4, 3:2), find the median number of siblings.
- 19th February 2024Data set X has a range of 12 and data set Y has a range of 5. Which data set is more consistent?
