The school's orchard is nearly ready for harvesting. The school has 3 hectares of commercial crop of kiwi fruit. Kiwifruit is produced for two main markets - export (these are finest grade kiwifruit) and the local supermarkets (these are the over/under sized or unusually shaped or marked kiwifruit).
Today we're going to measure out our sample from the orchard.I want you to have the length width height (all to nearest cm) and weight (nearest gm) measured.
We'll have a database formed for recording this information.
This we'll use to do some statistics and graphs in our investigation.
We will be looking to see if there is a relationship between the height and the weight of kiwifruit here at Waihi College.

Plan - how can we gather a 'fair' sample of fruit? What are we measuring and how are we measuring it? What units are we going to use? Are we rounding or making any judgement calls (e.g. a fruit with a hole in it? The measuring is evidence for the portfolio on measurement.
Data - we will record this on a spread sheet in class.
Analysis - we will use a scatterplot to show our data. We will make statements about what we see.
Conclusion - there maybe a relationship (maybe not). If there is - is that relationship positive/negative, strong? Can we make a logic statement about what happens with length and weight?
