4+Data+Analysis

Data Analysis: Based upon my readings, I believe my research will be inferential and QUAN (arrow) qual. I will focus on gains in student achievement first but will consider qualitative data collected afterward to determine whether or not the CAI made a difference in student performance. I plan to use significance testing. To assist me in the data analysis process, I hope to use a computer program such as SPSS. My null hypothesis would be: “The use of CAI (I will specify when sure) does not lead to improvement of student performance in math.” My alternative hypothesis would be: “The use of CAI (I will specify when sure) does lead to improvement of student performance in math.” To control the risk of errors, I will set a .05 significance level for my data. I will use SPSS to calculate the probability value for my significance testing. I will use the results of this calculation to either accept my null hypothesis or reject it. I will use a one-way analysis of variance (ANOVA) to compare data from my control and experimental groups.
