10 Experimental Research: One-Way Designs

• What types of evidence allow us to conclude that one variable

causes another variable?

• How do experimental research designs allow the demonstration

of causal relationships between independent and dependent variables?

• How is equivalence among the level of the independent variable

created in experiments?

• How does the ANOVA test hypotheses about differences between the

experimental conditions?

• What are repeated-measures experimental designs?

• How are the results of experimental research designs presented in the

research report?

• What are the advantages and disadvantages of experimental designs

versus correlational research?
