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.

Leonardo da Vinci (1452-1519) was a scientist and an artist. He thought that the span of someone’s arms was equal to their height. Why do you think he was interested in working out body proportions?

Do you think Leonardo’s theories still work today?

Was Leonardo’s theory that a person’s height is equal to their arm span true for New Zealand students in 2007?

How good are my reactions compared to other students?
