I have a question about t-test or ANOVA. A is the independent variable and has two levels (0,1). B is the dependent variable, each of whose values is a percentage. By means of SPSS or other instruments, how to compare the means of B under different levels of A, given such a type of data?

My concern is that whether t-test or ANOVA still applies due to the percentage dependent variable which does not follow the normal distribution?

Any suggestions would be appreciated, Thanks!
