five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05)‚ does showing the film change students’ attitudes towards the chronically mentally ill? What does it mean to set alpha at .05? Alpha means making a Type I error same as significance level. When the alpha is at .05 it means that the researcher doesn’t want to take a big risk therefore sets the alpha to .05. By doing this it will make it hard for hypothesis testing process to reject the null hypothesis unless it is
