# Comparing Data Distributions

'Whose results are best? Boys, Girls, Monkeys, Martians, Flying pigs, Babies or Robots?'

### Aims

The aim of this activity is for students to think critically about interpreting data and their calculations. The activity involves the calculation of measures of central tendency and dispersion. It involves the production of measures of box plots. Students have to identify the key differences between the data sets amongst that which they have in common.

### Resources

As suggested above, there are a number of ways to approach this task. The resources are below.

The most open approach to this task is to start with just the data and do your own analyses from scratch!

The Data - This is the seven data sets you need to do the analyses.

Otherwise, or as well, you can do these matching activities to help you unlock the secrets in the data.

Match the box plots and histograms - In this task you must match a box plot and a histogram to each of the data sets.

Match the descriptions - In this task, a summary analysis of each species is given and your job is to match it to the correct species.

Teachers will need to think briefly about how they want to run this activity by reading the  Comparing Data Distributions - TN teacher notes

#### The Data

Here is a screen shot of the data you will be working with....

### Description

• Students are presented with the data and the idea.
• Teachers decide how they want students to approach the task.
• Students can be presented with the raw data and asked to analyse, present and summarise.
• Students can do the matching exercise with the box plots and histograms.
• Students can do the matching exercise with the descriptions.
• Any of the above work can be put together to make a display.
