  6. Experimental validity • Internal validity • External Validity

  7. Threats to Experimental Validity • See page 141 & 142

  8. Experimental Designs • Posttest only Control group design • Pre-post test control group design • Solomon Four groups design (p.149) • Factorial Designs • Repeated Measures Design • Taking medicine and then repeatedly tested for the effect to kick in or fade away

  9. Quantitative Research DesignCorrelational Design • Describe or measure the degree of association between two or more variables or sets of scores. • Explaining • Predicting

  10. Quantitative Research DesignCorrealtional Design • Characteristics:

  11. Quantitative Research DesignSurvey Design • Survey Study • The researchers administer a questionnaire or interviews to a sample or a entire population to describe the attitudes, opinions, behaviors, or characteristics of the population.

  12. Quantitative Research DesignSurvey Design: Characteristics • Sampling from a population • Collecting data
