Data Analysis ChecklistAnalysis and conclusions Done

I have described what the data showsI have explained why the data shows thisI have linked my explanations to geographical theoryI have made links between the various resultsI have referred to the figure numbers when describing the data I have described and explained anomalies in the dataI have given an overall conclusion to the study and answered the initial questions

Now its your turn!In groups of 4 write the Data Analysis for the below

hypothesis.

Channel size or Cross Sectional area will increase with distance downstream.

REMEMBER: For the controlled assessment you will only be allowed to use bullet point notes to assist you in writing the data analysis.
