What is ANOVA? Learn about the different types of ANOVA: one-way ANOVA, randomized block ANOVA, and two-way ANOVA.
- A luxury resort recently gathered survey data…from their guests.…These results were all captured…within a one-week period in June.…The hotel guests were asked…to rate their resort experience…from a score of zero to ten.…Here are the survey results…reported by these hotel guests,…broken down by the age of the guest.…The question is, are these scores different…because of the difference in the age of the guest,…or is it possible that the reported scores…and their differences…were the result of random chance?…In this section,…we're going to discuss the Analysis of Variance,…often referred to as ANOVA.…
ANOVA is a procedure used to determine…if the variation between reported output…is the result of some particular factor,…or if the variation is simply the result of randomness.…In this case, we have one factor: age.…We also consider the number of levels.…In this case, we had three levels,…since guests were divided into three age ranges.…We're going to look at ANOVA procedures in action.…
But, before we begin,…we need to understand that ANOVA…
