Matched groups design - Study guides, Class notes & Summaries

When a researcher inadvertently creates a condition with a fundamentally different type of participant than another condition, this can create a ______. You can combat this by arbitrarily assigning participants to each level, known as ________. In some cases, especially with smaller sample sizes, researchers will assign participants to groups so that each group has a similar makeup for a particular attribute they may be concerned about. This is known as creating _______. selection effe...

Aim Ans: General statement of why the study is being carried out. Null Hypothesis Ans: An assumption that there is no relationship between the variables. E.g. There is no relationship between age and intelligence. Directional hypothesis (one-tailed) Ans: States the kind of relationship between two conditions. E.g. People who do homework without the TV on produce better results than those who do homework with the TV on. Non-directional hypothesis (two-tailed) Ans: Simply predicts tha...

Single-Factor Randomized, Two Groups - Answer One IV with 2 Levels / Between-Subjects Design Procedure: 1.) Participants are randomly assigned to two groups [ie: experimental and control] 2.) This is analyzed via a between-subjects t-test Disadvantage: *They cannot detect a non-linear effect* Single-Factor Randomized, Multiple Groups - Answer One IV with 3 or more Levels / Between-Subjects Design Procedure: 1.) Participants are randomly assigned into groups 2.) ...
