Clues

  • The purpose of this is to eliminate bias (13)
  • This design is a special case of the randomized block design and refers to when the experiment has only two treatment conditions; and participants can be grouped into pairs (7, 5)
  • This design refers to when the same participant takes part in every condition of the independent variable (8, 8)
  • This is the effect of factors other than those controlled by the experimenter (12, 5)
  • This type of trial is when neither the participant nor the person administering the treatment knows if they are in the experimental group or not (6, 5)
  • With this sampling method, groups or categories are proportionate to that of the population (10)
  • With this sampling method, the initial sample is small but through referrals after each sample is taken, the sample size increases exponentially (8)
  • With this sampling method, the population is split into groups or categories and a random sample is taken from one or two of these groups (7)
  • With this sampling method, the sample is taken at regular intervals from the population (10)
  • With this sampling method, the sample is taken in a way that is most convenient to the person collecting the data (11)
