Extraneous variables are problematic for claiming causality in research. Whereas researchers want to
  assume that the independent variable is truly causing the changes onto dependent variable, and that
  the effects are not due to other variables.
 
  A solid research methodology will account for all observed
  relationships among variables. According to the text, when can extraneous variables occur?
  a) Prior to the intervention (independent variable)
  b) Prior and after the intervention (independent variable)
  c) Prior and during the intervention (independent variable)
  d) Prior, during, and after the intervention (independent variable)

A team of social workers want to conduct research on discrimination in the workplace. They
  speculate that certain ethnic groups may be treated unfairly in terms of hiring practices and
  promotions.
 
  However, after reviewing preliminary documentation their emphasis shifts from ethnic
  groups to gender. Now the focus of the research is to determine if there is a relationship between
  gender and hiring practices. This focus of the research can be defined as:
  a) Hypothesis
  b) Theory
  c) Evidence-based
  d) Ethics

Henry is a social scientific researcher who has invested several years into studying the impact of
  cognitive-behavioral (CB) interventions.
 
  In terms of his biases, he favors CB and therefore is
  disappointed when research results do not support treatment effectiveness. Unfortunately, Henry
  decides to fabricate the data so outcomes will favor CB. What ethical breach did Henry enact?
  a) Psychological harm
  b) Misrepresentation of findings
  c) Monitoring study effects
  d) Balancing risks and gains
