PSYB01H3 Chapter Notes - Chapter 8: Dependent And Independent Variables, Internal Validity, Null Hypothesis
Document Summary
Can trying to ignore a text message lead to distraction? this one seems to make a more specific prediction about a type of behavior that leads to a specific outcome. As a result, our focus has moved beyond merely describing what is taking place to identifying how one factor (ignoring text messages) leads to changes in another factor (distraction) Need to use experimental research to help us determine cause and effect. We should let our question guide our design choice two main design types: Which focus on determining why something happens. Ability to identify cause-and-effect relations between variables. first you have to establish if there is covariation between two variables you must demonstrate that two variables vary or change together in a systematic way. A correlational study cannot establish causation, but it can establish covariation. When changes in the suspected cause (treatment) occur before changes in the effect (outcome). then you can establish independent and dependent variables!
