Every sheet in June 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 1996A question asks: 'Don't you agree that the new bus timetable is an improvement?' State what is wrong with this question.
- 2nd June 1996For the ordered data 2, 4, 5, 7, 8, 9, 11, 13, 14, find the lower quartile (Q1) and upper quartile (Q3).
- 3rd June 1996A pictogram shows 5 full symbols for apples sold, with a key of 1 symbol = 12 apples. How many apples were sold?
- 4th June 1996Using the two-coin sample space, find P(exactly one head).
- 5th June 1996A frequency polygon has classes of unequal width: 0-10 and 10-30. Explain why comparing the heights of the two plotted points directly can be misleading.
- 6th June 1996Explain why using a time series trend to estimate a value many years into the future is less reliable than estimating one year ahead.
- 7th June 1996Using your answers to the previous question, find the relative risk for phone users compared with non-users, and interpret it.
- 8th June 1996A pack of 10 cards is numbered 1 to 10. One card is drawn and not replaced; it is even. A second card is then drawn. Find P(second card is even given the first card was even).
- 9th June 1996A pie chart is drawn showing 3 sectors that look visually equal in size, but the data is 50%, 30% and 20%. What is wrong?
- 10th June 1996A class interval 0-10 has frequency 6. Find frequency x midpoint.
- 11th June 1996What is wrong with the question 'How old are you and do you smoke?'
- 12th June 1996What does a moving average smooth out in seasonal data, and what does the result reveal?
- 13th June 1996P(A) = 0.4 and P(B) = 0.35, where A and B are mutually exclusive. Find P(A or B).
- 14th June 1996A histogram has unequal class widths. Explain why the height of a bar can no longer be read directly as the frequency.
- 15th June 1996A box plot for 40 values has lower quartile 15 and upper quartile 25. Roughly how many of the 40 values lie between 15 and 25?
- 16th June 1996Explain why the median might be a more appropriate average to use on a data set with an outlier, instead of removing the outlier first.
- 17th June 1996A population falls from 8,000 to 7,600. Find the percentage rate of change, stating whether it is an increase or decrease.
- 18th June 1996A population of 90 people is split into 3 age groups: 30 aged 18 to 30, 40 aged 31 to 50, and 20 aged 51 or over. A stratified sample of 27 is needed. Find how many from the 51-or-over group should be sampled.
- 19th June 1996Using the same table (0:4, 1:10, 2:4, 3:2), find the range.
- 20th June 1996Team 1 has median height 165 cm and Team 2 has median height 172 cm. Write one comparison in context.
- 21st June 1996A base year value is 40 and this year's value is 50. Find the index number.
- 22nd June 1996A spinner has 8 equal sections numbered 1 to 8. What is P(the spinner lands on a number greater than 5)?
- 23rd June 1996A coin is flipped 50 times and lands on heads 27 times. Find the relative frequency of heads.
- 24th June 1996On a tree diagram, what do you do to find the probability of a single path through the branches?
- 25th June 1996On a pyramid where male bars point left and female bars point right, the bar for females aged 20-24 is longer than the bar for males aged 20-24. What does this tell you?
- 26th June 1996Describe, using the mean and median, how you could tell that a distribution is positively skewed without drawing a graph.
- 27th June 1996A sample of 25 students from a school of 500 found that 5 walk to school. Estimate how many of all 500 students walk to school.
- 28th June 1996Find the mean of 4, 7, 9, 12, 18.
- 29th June 1996A researcher wants a sample of 50 from a population of 500 using systematic sampling, with a random start of 4. List the first three people selected.
- 30th June 1996What is a control group used for?
