Join Yash Patel for an in-depth discussion in this video Scenario and context, part of SPSS for Academic Research.
- [Narrator] So far, we've been dealing with…two groups or two conditions.…Let's up the ante a little bit and move to…three groups, or three conditions.…Quite often, the type of test you'll use for…three groups or more is called…a one way ANOVA, or the one factor ANOVA.…The whole objective of this test is to determine…whether there's a significant difference…in the means of these three groups.…To be clear, the one way ANOVA can't tell you…which groups are different from one another,…just that at least one of the means…of the three groups is different.…
It's called an omnibus test.…You can do some post-hoc testing to figure out…which groups are actually different.…Now, you may be wondering, why can't I just…run multiple T tests instead?…Well, the ANOVA controls type one error rate.…That means that you're less likely to reject…the null hypothesis when it's actually true.…Okay, so now on to the one way ANOVA.…There's still one dependent variable…if you're doing human subjects research,…this might be an IQ score or a test score…
