An experimenter investigated the ability to concentrate as a function of crowding. Concentration was measured as the amount of time it took the participant to complete a word puzzle. How should the experimenter summarize the scores on the dependent variable?
 
  a. Find the mode for crowding because crowding scores are nominal.
  b. Find the mean amount of crowding, if crowding scores are normally distributed.
  c. Find the mean amount of time it took to solve the puzzle, if time scores are normally distributed.
  d. Find the median amount of time it took to solve the puzzle because time scores are ordinal.

Question 2
