Averages and range

Maths | KS3 | KS4

Learning Objectives

  1. Know how data is collected and analysed in a sporting context.
  2. Know what the mean, median, mode and range averages are and identify when and where you would use them.
  3. Describe the difference between mean, median, mode and range averages.
  4. Demonstrate and interpret the use of mean, median, mode and range averages from team data shown in charts and tables.
 

Lesson Description

This Maths topic uses the real-life context of the British America’s Cup team INEOS TEAM UK, to show the crucial role of data collection and analysis in developing the performance of both the boat and crew. Students will use data generated by the team to develop their learning of mean, median, mode and range of averages. The three differentiated worksheets reinforce learning objectives for this topic. The resources can be used either in sequence or flexibly as an introduction to a topic, or for a quick activity.

This film shows how INEOS TEAM UK collected data using state-of-the-art technology to monitor and improve their performance.

ENGLAND
KS3 NC Mathematics – statistics
Describe, interpret and compare observed distributions of a single variable through: appropriate graphical representation involving discrete, continuous and grouped data; and appropriate measures of central tendency (mean, mode, median) and spread (range, consideration of outliers).

GCSE Mathematics
Edexcel
S2 interpret and construct tables, including frequency tables.
S4 interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: appropriate graphical representation involving discrete, continuous and grouped data; appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers).

AQA
S3.3, S3.3h Calculate median, mean, range, mode and modal class from lists and tables of data.

WALES
KS3 Mathematics

Find the mean, median, mode and range from grouped frequency tables.
Find the mean, median, mode and range from ungrouped frequency tables and explain why it is an estimate.
Use mean, median, mode and range to compare two distributions (continous and discrete data).
Interpret diagrams and graphs to compare sets of data.
Examine results critically, select and justify choice of statistics recognising the limitations of any assumptions and their effect on the conclusions drawn.

KS4 Mathematics
Use the mean, median, mode and range from grouped frequency tables to compare distributions.
Calculate the upper quartile, lower quartile and interquartile range of a set of discrete data and use them to describe a data set.
Recognise and use the most appropriate data to compare distributions.

SCOTLAND
Fourth level Numeracy & Mathematics:
Compare numerical information in real life contexts by finding the mean, median, mode andrange of sets of numbers. Decide which type of average is most appropriate to use and discuss how using an alternative type of average could be misleading.
Select appropriately from a wide range of tables, charts, diagrams and graphs when displaying discrete, continuous or grouped data to clearly communicate the significant features of the data.

NORTHERN IRELAND
