December 2000 5-a-day
Printing for a group?
The batch download puts all 2 tiers' December 2000 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in December 2000
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st December 2000A researcher draws a bar chart from her results. Which stage of the cycle is this?
- 2nd December 2000Give one advantage of using a questionnaire to collect data.
- 3rd December 2000Find the median of: 4, 7, 9, 12, 15.

- 5th December 2000Two fair six-sided dice are rolled and the scores are multiplied together. How many cells are in the sample space diagram?
- 6th December 2000What value do you plot on the horizontal axis for each class of a frequency polygon?
- 7th December 2000A time series of monthly temperatures shows one May with a temperature far below every other May on record. What might this value be called?

- 9th December 2000A drawer has 7 black socks and 5 white socks. Two socks are taken without replacement. Find P(second sock is black given the first sock was black).

- 14th December 2000A 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).

- 16th December 2000Box 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?

- 20th December 2000Using the same table (0:4, 1:10, 2:4, 3:2), find the median number of siblings.
- 21st December 2000Data set X has a range of 12 and data set Y has a range of 5. Which data set is more consistent?
- 22nd December 2000An index number is 140 with a base value of 20. Find this year's value.
- 23rd December 2000A bag has 4 yellow and 6 white balls. What is P(picking a yellow ball)?
- 24th December 2000A dice is rolled 120 times and shows a 6 on 15 of those rolls. Find the relative frequency of rolling a 6.

- 26th December 2000A pyramid has a wide base and a narrow top. What does this suggest about the population?
- 27th December 2000A distribution has a long tail of high values on the right. What type of skew is this?
- 28th December 2000A quality inspector samples 120 items from a batch of 15000 and finds 3 defective, but the sample was taken only from items made in the last hour of the day. Explain why her estimate might not be reliable, and give the estimate assuming the sample were representative.
