Explain the role of controls in experiments, and how we deal with uncontrolled variables in quasi-experimental

  1. Explain the role of controls in experiments, and how we deal with uncontrolled variables in quasi-experimental designs.
  2. Define content validity, external validity, and reliability, and describe how these terms apply to research designs.
  3. Identify two specific difficulties with longitudinal studies, and explain how combining longitudinal with stratified designs can make such studies more efficient.
  4. Describe the problem with introspection as an experimental technique and identify at least 3 scientific faults with introspection as the basis of theory.
  5. Discuss the importance of random selection and random assignment in setting up an experiment.
  6. Discuss advantages and disadvantages of using survey data, including problems with missing data, obtaining a random sample, and data analysis with open-ended vs. forced response types of questions.
  7. You will find a set of data under the file name GSS84 in the examples files for SPSS that you copied. This data reflects a survey of the general population in 1984 . The variables are identified by name and, in most cases, description.
  1. What strategy would you use to analyze this data to determine the effects of race and gender on respondent's total income?
  2. Analyze the data and print the results.
  3. Interpret your results: what effects are significant? What effects are not significant?
  4. Perform the same analysis on the 1993 social survey in the SPSS examples files on the school network or in the files you copied, compare the results with your GSS84 analysis, and suggest a hypothesis for any differences you find between them.
