Chantal is about to conduct a study and is trying to decide how to assign people to her two
  groups in a way that will spread any extraneous variables, such as individual differences of the
  participants, equally among the two groups.
 
  She asks you to recommend the best way to assign
  participants to groups. What should be your first question before offering a suggestion?
  A) How many DVs do you have in the study?
  B) How many participants are there in each group?
  C) How will the IV be administered?
  D) How many participants are related?

Question 2

A researcher conducts a study and finds a mean of 65 and 95 confidence interval range of 60-70. This means that
 
  a. there is a 95 probability that the true mean is within 60 and 70.
  b. 95 of the data points fell between 60 and 70.
  c. the researcher is 95 confident that the mean found in this study was 65.
  d. if the study was repeated multiple times, the calculated confidence interval would be between 60 and 70 in 95 of those studies.
  e. if the study was repeated multiple times, the calculated confidence interval (which would be unique for each study) would encompass the true population mean in 95 of those studies.
