In a study to investigate the effect of e- learning, a researcher hypothesized that different teaching methods, namely, classroom teaching, video recording, and real-time zoom meeting, have different effect on learning and therefore have different degree of satisfaction. Traditional classroom teaching cannot be replaced due to intensive personal interactions between teachers and students. Data were collected from a university about their satisfaction towards the course Introduction to Psychology (more positive value, higher level of satisfaction). The researcher has used the data to test his hypothesis that students undergoing different methods of instruction differs in their satisfaction towards the course. Below shows some SPSS output of the researcher's analysis: Descriptives satisfaction N Mean Std.
