Last Friday, I finished the final presentation. This week which is also the last week, I should focus on the report. The report should cover all what I've done in the past 12 weeks, and discussions about the result.

Up to now, I have finished almost all the data analysis and the results are to be reviewed after preparing the presentation. Some of the results are not significant as expected, and I am trying to think about the reasons. It may cause by learning effect or other factors like gender, age and so on.

I plan to focus on editing the report from next Monday and hope I can finish it before the 24th. The final presentation will be on next Friday.

I am now doing the ANOVA test to three main features -- percentage of higher than upper bounds, average pressure and number of overcorrection. As Excel cannot do the one-way repeated measures ANOVA,  I am learning to use SPSS.

From the book, I understand that I should firstly draw some graphs like frequency histograms to get an overview of the data before doing the intensive analysis.

I still have some problems in data normalization. I am still not sure what type of data needs normalization and which formula is the best.
