The children collected data about the children in their class.  They input this into a database and made charts.  Then we  studied the charts to see what we could find out.  We discovered that more people were right handed than left handed and that most of the left-handed people were boys.

On the bottom two charts, the lines followed a similar pattern, so we found out that if you have small feet, then you are more likely to have small hands.  Tall people seem to have bigger feet, probably for balance. 

It seems that if you are a Year 5 - you are far more likely to have a brother than a sister - 80% of the children have a brother.

We realise we would need a much bigger sample to prove these facts for certain, but our sample was interesting.
