Chapter #9 Flashcards
(16 cards)
Empty Control Group:
A group of participants who complete the dependent measure without receiving any treatment
Placebo Group:
An experimental group whose participants falsely believed they are receiving the experimental treatment
What is a Between-Subjects Design:
Each participant was tested in only one condition
When to Use a One-way ANOVA Test:
With an independent variable having 3 or more levels and a dependent variable measured on a continuous scale
What Does a Chi-Square Test of Independence Measure
The categortical/behavioural measure
When Are Post-hoc Tests Used?
If the ANOVA shows a significant difference among the levels of the independent variable
They compare all possible pairwise combinations of levels of the independent variable
What is Hypothesis-Guessing?
When a participant in a study actively attempts to identify the purpose of the research
What is Methodological Pluralism?
The use of multiple methods or strategies to answer a research question
What is the Multigroup Design?
An experimental design with three or more groups
What is a Nonlinear (or Functional) Relationship?
Any association between variables that using just two comparison groups cannot uncover. These relationships, often identified on a graph as a curved or curvilinear line, help provide us with a clearer picture of how variables relate to one another
What is the Study’s Power?
A study’s ability to find differences between groups when there is a real difference (false null hypothesis); the probability that a study will yield significant results
What is the Confound Effect?
A variable that the researcher unintentionally varies along with the manipulation
What is an Empty Control Group?
A group that does not receive any form of the treatment and just completes the dependent variable
What is an Explanatory Analysis?
Statistical tests that examine potential differences that were not anticipated or predicted prior to conducting the study
What is a Post-hoc Test?
Statistical tests that examines all possible combinations of conditions in a way that statistically accounts for the fact that not all of them were predicated ahead of time
What are Planned Contrasts?
Statistical tests that examine comparisons between groups that were predicted ahead of time. These tests have the added benefit of allowing the comparison of combined conditions to other conditions in the study
