Printing for a group?
The batch download puts all 2 tiers' October 2002 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in October 2002
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st October 2002A survey question offers the response options 'Never, Sometimes, Always'. State one improvement that could be made.
- 2nd October 2002Find the 3-point moving average of 10, 14, 18.
- 3rd October 2002A bag has only red, blue and green counters. P(red) = 0.5 and P(blue) = 0.2. Find P(green).
- 4th October 2002A histogram has bars of equal width. True or false: the height of each bar represents the frequency for that class.
- 5th October 2002A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 6th October 2002A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 7th October 2002A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 8th October 2002A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 9th October 2002Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 10th October 2002Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 11th October 2002An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 12th October 2002An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 13th October 2002Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 14th October 2002A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
- 15th October 2002On a population pyramid, which axis shows the age groups?
- 16th October 2002A box plot shows a long whisker on the left and a short whisker on the right, with the median close to the right of the box. What type of skew does this suggest?
- 17th October 2002A survey of 30 shoppers out of 900 in a store found the mean amount spent was 18.50 pounds. What is the best estimate of the mean amount spent by all 900 shoppers?
- 18th October 2002Find the median of 8, 3, 15, 3, 10.
- 19th October 2002A school of 600 students wants a sample of 30. A teacher decides to only survey students in her own class of 30. State one problem with this method.
- 20th October 2002A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 21st October 2002The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 22nd October 2002In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 23rd October 2002A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 24th October 2002A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 25th October 2002A researcher finds that towns with more fire engines have more fire damage, and concludes that fire engines cause fire damage. Identify the flaw in this reasoning and suggest the true common cause.
- 26th October 2002Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 27th October 2002What is a pilot survey?
- 28th October 2002Is 'height of a plant in cm' discrete or continuous data?
- 29th October 2002Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
- 30th October 2002Using the survey in the previous question (Red 6, Blue 9, Green 4, Yellow 5), which colour is the mode?
- 31st October 2002A bar chart uses a scale where each small square represents 2 people. A bar is 7 squares tall. How many people does the bar represent?
