But if we taped those million boxes and measured the peel strength, we would have used up all of the tape. If you could tape 1 million boxes from a batch of tape, those million might represent the entire population that we want to know about. Inferential analysis is the formal way of saying that we want to look at a sample of measurements and make an educated guess about what all of the possible measurements might be like if we could take them. All the strength measurements for the same supplier’s tape form a group of measurements.ĪNOVA is an inferential statistical analysis. For example, if you want to know whether tapes from three different suppliers have the same peel strength, the suppliers are your factor. While ANOVA has many varieties, the essential purpose of this family of analyses is to determine whether factors have an association with an outcome variable.įactors are the variables that you will use to categorize your outcome variable into groups.
