5 Matching questions

  1. quasi-experimental design
  2. no-treatment control group
  3. instrumentation:
  4. population generalizability
  5. meta-analysis
  1. a The degree to which results of a study can be applied to other settings or conditions
  2. b consistency and reliability
  3. c does not use random assignment as a means of control
  4. d participants receive no treatment at all
  5. e a statistical procedure for examining the results of several research studies on the same topic and determining the congruence and divergence of outcome data

5 Multiple choice questions

  1. unpredictable fluctuations in instruments, participants, or conditions
  2. This often occurs in single-subject experimental design or some pretest-posttest designs. This option provides high internal validity because participants serve as their own controls.
  3. used to survey different samples from a population whose members may change over time
  4. describe an existing phenomenon by using members to characterize individuals or groups
  5. researchers manipulate variables or introduce a treatment to one participant or group over time and intently study effects

5 True/False questions

  1. Methods of Control:this tests the main and interaction effects of categorical variables on a continuous dependent variable, controlling for the effects of selected other continuous variables that covary with the dependent variable

          

  2. external validitygeneralizability

          

  3. casual-comparative studiesobserve and describe some current condition; but, rather than introduce treatments, researchers look to the past to try to identify possible cause

          

  4. random assignmenta randomization process that is usually done after the research participants are selected to determine which participants will receive which value of the independent variable

          

  5. content-related evidenceincludes a variety of different types of evidence supporting the characteristic being measured. Three common ways to measure construct-related validity include using a clearly defined variable, hypotheses based on theory to explain the variable, and logical and empirically tested hypotheses.
