Printing for a group?
The batch download puts all 2 tiers' November 2005 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in November 2005
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2005Find the midpoint of the class interval 10-20.
- 2nd November 2005A survey question offers the response options 'Never, Sometimes, Always'. State one improvement that could be made.
- 3rd November 2005Find the 3-point moving average of 10, 14, 18.
- 4th November 2005A bag has only red, blue and green counters. P(red) = 0.5 and P(blue) = 0.2. Find P(green).
- 5th November 2005A histogram has bars of equal width. True or false: the height of each bar represents the frequency for that class.
- 6th November 2005A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 7th November 2005A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 8th November 2005A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 9th November 2005A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 10th November 2005Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 11th November 2005Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 12th November 2005An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 13th November 2005An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 14th November 2005Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 15th November 2005A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
- 16th November 2005On a population pyramid, which axis shows the age groups?
- 17th November 2005A 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?
- 18th November 2005A 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?
- 19th November 2005Find the median of 8, 3, 15, 3, 10.
- 20th November 2005A 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.
- 21st November 2005A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 22nd November 2005The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 23rd November 2005In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
- 24th November 2005A Venn diagram shows 40 people: 22 own a car, 15 own a bike, 6 own both. Find the probability a random person owns neither.
- 25th November 2005A scatter graph shows points scattered with no clear pattern. What type of correlation does this show?
- 26th November 2005A 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.
- 27th November 2005Two data sets give correlation coefficients rs = 0.6 and rs = -0.9. Which shows the stronger relationship?
- 28th November 2005What is a pilot survey?
- 29th November 2005Is 'height of a plant in cm' discrete or continuous data?
- 30th November 2005Three groups have 8 items with mean 10, 12 items with mean 15, and 5 items with mean 20. Find the combined mean.
