Students will need to be familiar with the background information to the data set.  This may involve looking at the variables in the dataset, looking at how the data was collected and measured, looking at the survey question that was asked to get the data.

In this activity students will be exploring the given data cards in response to investigative questions they have posed.  In some instances students might organise the data cards and then pose their investigative question once they have found something of interest in their data cards (EDA- exploratory data analysis).

This activity will also allow students to develop the language of description for summary situations.

Do boys have longer arm spans than girls?

Do our arms get longer as we get older?

In this activity you will explore whether the length of your arm span is related to how old you are.

To give an awesome bear hug you need really long arms so that your arms get all the way around the person you are hugging.

Does the average student have arms long enough to give a bear with a circumference of 160cm a hug?

In this activity you will explore how long the average arm span is.
