Statistics GCSE coursework
In my DT lesson our teacher told us to draw a 25cm line and I drew mine too big and the teacher told me to get better at maths. I did not think this would improve my ability to estimate a length of a line so decided to find out. The questions I thought up are:
1) Is there any relationship between estimating a length of a straight line linked to mathematical ability?
Null hypothesis: There is a relationship between them.
Alternative hypothesis: There is no relationship between them.
2) Does the estimation of a non straight line improve after practice?
Null hypothesis: Practice improves the estimation of a non straight line.
Alternative hypothesis: Practice doesn't improve the estimation of a non straight line.
3) Does a 14/15 year olds ability to estimate the length of a straight line fit a normal distribution?
Null hypothesis: A 14/15 year olds ability to estimate a straight line fits normal distribution.
Alternative hypothesis: A 14/15 year olds ability to estimate a straight line doesn't fit normal distribution.
4) Are a 14/15
