Document Summary

Often referred to as a comparison of means test. Can be used when: independent variable is measured at the nominal or ordinal level, and the dependent variable is measured at the interval/ratio level. A lot of our independent variables vary- such as happiness (1) the distance, or deviation, of raw scores from their group mean - this is known as. Variation within groups, and, (2) the distance, or deviation, of group means from one another - this is known as. All have some overlap and within each group there will be some variations. When you compare between groups you always use the mean. We use all the values so that it is easier to compare. When we have groups we have different sums of squares but each type represents the sum of sum deviations from the mean. Happiness measured on a scale from 1 to 10 (example)
