Week 3 : 1/23-1/27

In this week, we planed to get 5 people for the experiment and it was successful. We are planing to do this every week in order to get 60 people by April. We also started using the spreadsheet to record the data result and we found that there are lots of useful functions in spreadsheet that we can use to calculate our data. Since I learned those functions before, I'll try to recall my memory and learn them.
