Determine whether the samples are independent or consist of matched pairs. (a) A speed training method is tested by comparing the 100 m times of a group of sprinters who used this method with a group of sprinters who used a different method. O independent samples O matched pairs (b) The amount of water that a random sample of families use per day is measured twice--once before they view a conservation video, and again one week after viewing this video. O independent samples O matched pairs
