5 Written questions

5 Matching questions

  1. Confidence Interval
  2. convieninece sampling
  3. p-value
  4. Structured observation
  5. negative correlation
  1. a Often an observer intervenes to exert control or setup a situation
  2. b The level of certainty that the true score falls within a specific range. The smaller the range the less the certainty. If intervals between two groups do not overlap you can infer differences based on the data
  3. c selected respondents primarily because of their availability and willingness to respond
  4. d for statistical significance. Low p-value most likely means type II error
  5. e as the value of one measure increases the value of another decreases

5 Multiple choice questions

  1. can be affected by the experience of being observed can be affected by biases but biasis can be minimized by training observers or keeping them blind to participants information and also getting participants habituated to being observed
  2. identification of units of behavior according to specific criteria that are related to the goals of the study
  3. when researchers biases determine which behaviors they choose to observe and when observers expectations about behavior lead to systematic errors in identifying and recording behavior.
  4. only those who volunteer participate
  5. measures how accurate the sample mean is of the population mean. The equation is SE+ SD/ square root of n

5 True/False questions

  1. successive independent samplesselected respondents primarily because of their availability and willingness to respond


  2. longitudinal designThe extent to which there is evidence that a test measures a particular hypothetical construct.


  3. discriminant validityWe want to see that our data is related to actual experience and actual validity


  4. indirect observationresearchers examine evidence of past behavior using physical traces or archival records


  5. populationthe set of all cases of interest. i.e if you are looking for student behavior at smu the population is all the smu students
