Obtaining a strong positive correlation between these two variables would mean that the more difficult the agents’ goals, the more insurance they tended to sell. Why would this be called a test of association? That is because you are determining whether there is an association, or relationship, between the predictor and criterion variables. , there is no random assignment or experimental manipulation that creates a difficult-goal sample versus an easy-goal sample). To be thorough, it is worth mentioning that there are some relatively sophisticated procedures that also allow you to perform a third type of test: whether the association between variables is the same across multiple groups.

A true zero point can be found only with variables measured on a ratio scale. Ratio Scales Ratio scales are similar to interval scales in that equal differences between scale values have equal quantitative meaning. However, ratio scales also have a true zero point which gives them an additional property. With ratio scales, it is possible to make meaningful statements about the ratios between scale values. For example, the system of inches used with a common ruler is an example of a ratio scale.

The other 50 agents assigned to the “easy-goal” condition have been told to make just five cold calls to potential policyholders per week. 2. 2 Design of the Experiment Used to Assess the Effects of Goal Difficulty Group Treatment Conditions Under the Independent Variable (Goal Difficulty) Results Obtained with the Dependent Variable (Amount of Insurance Sold) Group 1 (n = 50) Difficult-Goal Condition $156,000 in Sales Group 2 (n = 50) Easy-Goal Condition $121,000 in Sales After 12 months, you determine how much new insurance each agent has sold that year.
