Explain what is a quasi-experimental research design? When are such designs used, and why?
Develop a conceptual replication and a constructive replication that investigate the expected boundary conditions for the original relationship.
Identify the purpose of the replication and the type of replication that was used. What are the important findings of the research?
Why it never possible to know whether research finding will generalize to all populations of individuals? How do behavioral scientists deal with this problem?
What is the purpose of review papers and meta-analyses? What are the differences between the two?
What is the purpose of replication? What are the differences among exact, conceptual, and constructive replications?
How does ecological validity help increase confidence that an experiment will generalize to other research settings?
In what ways are experimental research designs preferable to correlational or descriptive designs? What are the limitations of experimental designs?
How does the Analysis of Variance test hypotheses about differences between the experimental conditions?
How do experimental research designs allow us to demonstrate causal relationships between independent and dependent variables?
Calculate the Pearson correlation coefficient between the variables. Was your hypothesis about the nature of the correlation supported?
In what ways can correlational data provide information about the likely causal relationships among variables?
What is the difference between a common-causal variable, an extraneous variable, and a mediating variable?
What are a linear relationship and a curvilinear relationship? What does it mean if two variables are independent?
When are correlational research designs used in behavioral research? What are their advantages and disadvantages?
How can correlational data be used to make inferences about the causal relationships among measured variables?
What can you conclude about the finding? List two other pieces of information that you would need to know to fully interpret the finding.
What is the purpose of means comparisons, and what different types of means comparisons are there? What do they tell the researcher that the significance test.
What are main effects, simple effects, and interactions? How should significant main effects be interpreted when one or more of interactions are significant?
What are three advantages of factorial experimental designs over one-way experimental designs?
What is the purpose of means comparisons, and what statistical techniques are used to compare means?
Compare the means of the two halves using a one-way ANOVA. Was random assignment to conditions successful in creating equivalence?
Identify and provide a label for the independent and dependent variables. Indicate number of levels in independent variable, and provide a label for each level.
Differentiate between random sampling and random assignment. Which is the most important in survey research, and why?
