Discuss whether or not Sapna’s visual representation was an appropriate way to represent this information.

The table shows information about the number of films that each of 12 students watched during one week.

Work out the mean number of films watched per student.

The mean number of films watched by twelve pensioners in the same week is 1.5

Alina claims that the students watched more television in this week than the pensioners.

Explain why Alina’s claim may be incorrect.

For each of the three diagrams below, state whether the mode, median or mean would be the most appropriate average to use to summarise the data.

Claire has a spinner.

She spins the spinner 10 times and records the colour the spinner lands on. It lands on red 3 times.

Using Claire’s results, estimate the probability that the next time she spins the spinner it will land on red.

Dhiyan spins the same spinner 50 times and records the colour the spinner lands on each time.

Here are Dhiyan’s results.

Using Dhiyan’s results, estimate the probability that the next time he spins the spinner it will land on red.

Whose data will give a more reliable estimate for the probability, Claire’s or Dhiyan’s? Give a reason for your answer.

Considering Dhiyan’s results, is the spinner fair? Give a reason for your answer.

Tim recorded the number of sheep on each of eight farms. The results are shown below.

44 41 72 74 68 80 68 97

Work out the median.

Tim recorded the number of sheep on the eight farms incorrectly. There are 2 more sheep that need to be included on every farm.

Work out the new median.

Tim also recorded the number of cows and the number of pigs on each of the eight farms. The mean number of cows is 48 The mean number of pigs is 70

Compare the number of cows with the number of pigs for these eight farms.

Tim plans to compare the two sets of data using the interquartile range.

Which average would be the most appropriate to use with the interquartile range?

Leya has collected data about 15 butterflies.

The table gives information about the length of time, in days, each butterfly lived.

Length of time lived (d days)	Frequency
0 d 3	7
3 d 6	4
6 d 9	3
9 d 12	0
12 d 15	0
15 d 18	1

Leya uses the table to calculate an estimate for the mean length of time these butterflies lived. Her estimate for the mean is 4.5 days.

Without performing a calculation, explain why Leya’s value for the mean is an estimate.

Explain why using the mean to represent the average length of time these butterflies lived may not be appropriate.

Freya wants to work out the life span of the light bulbs produced at her factory.

She selects a random sample of 50 light bulbs, and measures the time taken for each light bulb to fail.

Explain why conducting a random sample was more appropriate than conducting a census.

Mandeep visited Marple Wood Farm and tallied the types of animals he saw.

Circle the word in the list below that best describes the type of data for the types of animals.

Quantitative Discrete Continuous Categorical

The incomplete tally chart and incomplete bar chart give some information about Mandeep’s results.

Complete the tally chart and the bar chart.

This is a sign at the entrance to the farm.

Mandeep tallied 55 animals during his visit. Using his results, Mandeep claims that the most common animal in the farm is a chicken.

Give two reasons why Mandeep’s claim may be incorrect.

A teacher wants to investigate how many hours students spent revising for a test.

20 students have to complete a short questionnaire before they begin the test.

This is a copy of the questionnaire.

State one advantage of using a short questionnaire instead of interviewing each student.

State the type of question used as Question 2

The table below shows the data collected for Question 2

Give a reason why this data needs to be cleaned.

The teacher cleans the data. The teacher wants to display information about the test mark each student got compared to the number of hours this student revised.

The teacher plans to draw a diagram for this information. The diagram will be shown on a poster where these students can see it.

From the list below, circle the type of diagram it would be best to use for this target audience.

Box plot Pie chart Scatter diagram Cumulative frequency chart

A store manager wants to show the employees which department is making the most profit.

The store manager presents the data in this pie chart.

Explain why the use of a pie chart may not be appropriate to show which department is making the most profit.

The raw data is summarised in the table.

Suggest a more appropriate diagram to represent and compare the profits made in the different departments.

The scatter diagram shows the marks each of ten students got for a Maths test and for a Music test.

One of these points is an outlier.

On the diagram, draw a circle around the outlier.

Excluding the outlier, describe the correlation shown in the diagram.

The outlier is removed from the data. The mean of the Maths marks is 52 The mean of the Music marks is 63

Excluding the outlier, draw a line of best fit that passes through the double mean point on the scatter diagram.

30 students did both tests. The scatter diagram shows the marks of 10 of these students.

Suggest one adjustment that could be made to improve the reliability of any conclusions made using the scatter diagram.

The diagram shows information about managers in Australia from 2016 to 2017

Managers in Australia 2016–17

18 16 14 12 10 8 6 4 2 0 0 2 4 6 8 10 12 14 16 18

State the name of this type of diagram.

Find the age group that the greatest proportion of managers are from. You should justify your answer.

A professor of sports science wanted to test if listening to music improved running performance.

She tested a sample of 20 adult males. All the males were similar in age and in fitness level.

The professor completed the study as a laboratory experiment. She asked all the males to run as far as they could in six minutes.

Each male ran twice. The first time he ran he listened to music. The second time he ran he did not listen to music.

Give two advantages of the professor completing this study as a laboratory experiment.

The professor believes the explanatory variable in this experiment is if the runners are listening to music or not.

State the response variable in this experiment.

One extraneous variable in this experiment is the type of music that the runners listen to.

How could the professor control this extraneous variable?

Explain why it is important to control extraneous variables in experiments.

Henry is investigating the price of some ingredients needed to make a cake.

The table shows the price index of twelve eggs and 1 kilogram of sugar in the UK in the years 2010, 2015 and 2020

The base year price is 2010 for both ingredients.

(Source: © Office for National Statistics)

Calculate the percentage change in the price of twelve eggs between 2010 and 2020

In 2010, the price of 1 kilogram of sugar in the UK was 95 p.

Calculate the price of 1 kilogram of sugar in 2020 Give your answer correct to the nearest penny.

In 2020, the total cost of all the ingredients was 450 p. Henry predicts that he will not have to pay more than 450 p for the same ingredients today.

Comment on the appropriateness of Henry’s prediction. Give a reason for your answer.

Elise wants to investigate the relationship between the size of mammals and the size of the fruits and seeds that these mammals eat. This is her plan.

Discuss the appropriateness of Elise’s hypothesis and her data collection strategy.

Divyesh is investigating the number of games won by two Los Angeles basketball teams, the Clippers and the Lakers. He collects some data from the NBA website.

Complete the sentence with an appropriate statistical word.

Divyesh has collected data from the internet and so this is_........ data.
