Printing for a group?
The batch download puts all 2 tiers' November 2022 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in November 2022
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2022A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 2nd November 2022A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 3rd November 2022A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 4th November 2022A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 5th November 2022Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 6th November 2022Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 7th November 2022An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 8th November 2022An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 9th November 2022Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 10th November 2022A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
- 11th November 2022On a population pyramid, which axis shows the age groups?
- 12th November 2022A 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?
- 13th November 2022A 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?
- 14th November 2022Find the median of 8, 3, 15, 3, 10.
- 15th November 2022A 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.
- 16th November 2022A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 17th November 2022The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 18th November 2022In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 19th November 2022A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 20th November 2022A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 21st November 2022A 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.
- 22nd November 2022Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 23rd November 2022What is a pilot survey?
- 24th November 2022Is 'height of a plant in cm' discrete or continuous data?
- 25th November 2022Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
- 26th November 2022Using the survey in the previous question (Red 6, Blue 9, Green 4, Yellow 5), which colour is the mode?
- 27th November 2022A 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?
- 28th November 2022A stem-and-leaf row, with key '3|1 means 31', is '3|0 2 4 4 7 9'. Find the median of these six values.
- 29th November 2022A frequency table has class frequencies 5, 9, 14, 7 for four consecutive classes. Find the cumulative frequency of the third class.
- 30th November 2022A choropleth map of rainfall uses two different hues (for example yellow to red) rather than one hue getting darker. Why can this style of shading be a problem?
