Teaching has many variables and much data to be collected. There are many ways to collect student data ranging from Guttman chats to bell curve graphs easily created on Excel. I analysed my students data using a bell curve. I used this to firstly easily see students and the low end as well as the high end and then those that were the average. However, using a bell curve allows teachers to see how far below the mean certain students are and how they could then be given extra attention.
