Your write up must include the following:
Brief introduction to the coursework task
Why and how pilot study was carried out
Why and how a stratified random sample was taken and any possible limitations
Findings from pilot study
State refined hypotheses (to include variation across years and gender)
How you will prove/disprove your hypotheses (i.e. What calculations and analysis you will make- Explain which calculations will prove which hypothesis and WHY you use them/what they show)
Why/how sample is taken; How many; What groupings
How you will eliminate bias/deal with outliers (include evidence)
Scatter graphs for each group, correlation coefficient, line of best fit and equation (where appropriate)
Min, max, lower and upper quartiles and median for heights or weights of each group
Box and Whisker diagrams (on same sheet for later analysis)
Mean and standard deviation for heights or weights.
Summary table(s) of calculated values
Correlation shown on each scatter graph and what they evidence
Comparison of correlation values across the groups
Explain your equations of lines of best fit and use to make predictions/inferences (include calculations)
Comparison of height/weight between boys/girls
Comparison of height/weight across year groups
Refer to box and whisker diagrams and what they demonstrate
Refer to mean and standard deviation and what they demonstrate
Relate findings to original hypotheses. Do your findings support them?
Give/suggest reasons for your findings
Give/suggest reasons for exceptions to patterns in your data
Was your sample a good/fair/representative sample?
Any limitations of the project?
Any problems you faced and changes you would make
