- Control/Trial 1: 32 votes of yes out of 600 participants
- Trial 2: 28 votes of yes out of 576 participants
- Trial 3: 59 votes of yes out of 602 participants
- Trial 4: 21 votes of yes out of 613 participants
- Trial 5: 35 votes of yes out of 584 participants

So I'm trying to figure out which test applies here since the number of votes is an independent variable but the number of participants is also not constant. I want to compare all of the trials together to determine which trial was the most successful and therefore which trial (technically each trial is a company test on which method to use regarding a certain project) should be approved.

I thought it would be a one way ANOVA but now I'm wondering if it should be a two way ANOVA since the group size varies for each trial. Whichever method I do use though, I also can't figure out how to actually process the data (i.e. is there a calculator I can use to determine the significance of each trial (2-4) compared to trial 1 which is technically the control?
