Printing for a group?
The batch download puts all 2 tiers' May 2006 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in May 2006
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 2006A pictogram key shows 1 symbol = 10 pupils. A row has 3 full symbols. How many pupils does the row represent?
- 2nd May 2006Two fair six-sided dice are rolled and the scores are multiplied together. How many cells are in the sample space diagram?
- 3rd May 2006What value do you plot on the horizontal axis for each class of a frequency polygon?
- 4th May 2006A time series of monthly temperatures shows one May with a temperature far below every other May on record. What might this value be called?
- 5th May 2006In a trial, 3 out of 150 patients taking a new drug had side effects. Write this risk in '1 in n' form.
- 6th May 2006A 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).
- 7th May 2006A line graph's horizontal (time) axis has unequal gaps between the years labelled: 2010, 2011, 2015, 2016. Why could this mislead a reader?
- 8th May 2006The table shows weights, in kg, of 20 parcels: 0-5 (freq 4), 5-10 (freq 10), 10-15 (freq 6). Estimate the mean weight.
- 9th May 2006Rewrite the response options '0-5, 5-10, 10-15' so that they no longer overlap.
- 10th May 2006A series of 4-point moving averages is 45, 48, 52, 55. Describe the trend shown by these values.
- 11th May 2006A 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).
- 12th May 2006State one reason why a histogram has no gaps between its bars, unlike a bar chart.
- 13th May 2006Box 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?
- 14th May 2006A shop records daily sales in pounds: 340, 355, 360, 348, 2, 352. Which value looks like a data entry error?
- 15th May 2006A town of population 10,000 records 20 births in a year. Find the crude birth rate per 1000 people.
- 16th May 2006A researcher wants a stratified sample of 30 from a population of 300 split into three regions: North (90 people), South (150 people) and East (60 people). She actually samples 9 from the North, 14 from the South and 7 from the East. Show whether her sample is correctly stratified, stating the correct numbers if not.
- 17th May 2006Using the same table (0:4, 1:10, 2:4, 3:2), find the median number of siblings.
- 18th May 2006Data set X has a range of 12 and data set Y has a range of 5. Which data set is more consistent?
- 19th May 2006An index number is 140 with a base value of 20. Find this year's value.
- 20th May 2006A bag has 4 yellow and 6 white balls. What is P(picking a yellow ball)?
- 21st May 2006A dice is rolled 120 times and shows a 6 on 15 of those rolls. Find the relative frequency of rolling a 6.
- 22nd May 2006A bag has 4 green and 6 yellow balls. One ball is drawn, replaced, then a second is drawn. Find P(both yellow).
- 23rd May 2006A pyramid has a wide base and a narrow top. What does this suggest about the population?
- 24th May 2006A distribution has a long tail of high values on the right. What type of skew is this?
- 25th May 2006A 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.
- 26th May 2006Find the mode of 5, 6, 5, 8, 6, 6, 9.
- 27th May 2006State one disadvantage of quota sampling.
- 28th May 2006Give one reason why participants should be assigned to groups at random.
- 29th May 2006A class interval is written 10 <= x < 20. Which of these values belong in it: 10, 20, 15?
- 30th May 2006A pie chart represents 60 people. What angle represents 1 person?
- 31st May 2006A rectangle labelled 20 contains two non-overlapping circles for events A and B with 8 and 5 inside them. How many outcomes are outside both circles?
