Table : TABLE 14-8. A Two-Way Between-Groups ANOVA Dutch researchers designed a study to examine what style of decision making led to the best choices in less complex and more complex situations. Would you predict an interaction? In other words, would the lines connecting bars on a graph be different from parallel? And if they are different from parallel, how are they different? If they are different just in strength, we are predicting a quantitative interaction. If the direction of effect actually reverses, we are predicting a qualitative interaction.
