Join Yash Patel for an in-depth discussion in this video Assumptions and hypotheses, part of SPSS for Academic Research.
- [Instructor] There are several assumptions…with which your data structure has to comply…when using a one way anova.…I'll break 'em down for you.…Assumption one is generally the same across all these tests.…We have one dependent variable, in this case salary,…that is measured on a continuous level.…Our second assumption is…that we have one independent variable,…in our case the college major,…with two or more categorical, independent groups.…These groups are our three majors:…kinesiology, finance, and engineering.…Notice that I did say two groups.…
You can use the anova for two groups,…but the independent samples T-test is generally used…for that, also known as the student's T-test.…If you have two independent variables,…say college degree and type of college,…like public versus private,…you'd want to use a two way anova…described in the next chapter.…The third assumption for this test…is independence of observations.…Let me simplify that.…No one from the kinesiology group…can be in the finance group,…and no one from the finance group…
