Foot+and+Forearm+Investigation

Foot and Forearm investigation:

1. Question: I will investigate if there is a relationship between foot length and forearm length?

2. Plan: We will measure the length of 30 student's forearms and right foot lengths using a 30cm ruler and measuring to the nearest cm. To make sure our measurements are consistent (or, to manage our variations) we will measure the inside of the forearm from the bend in the arm to the base of the palm. When measuring the right foot length we will measure from the base of the heel to the longest toe.

3. Data table (see excel spreadsheet) 4. Scatter grapsh (see excel spreadsheet) 5. Usually (or, it tends to be that) the longer the foot length the longer the forearm length. My graph is positive and moderate as the plots are reasonably close to the trendline. There is an outlie at............. I know it is an outlier because it is far away from my trendline and requires further investigation.

You can comment on any clusters (that's where there may be a distinct group of data); there could be two clusters... again, further investigation is required.
