Answers for Independent vs. Paired



  1. A worker's productivity measurement with music is paired with a productivity measurement for the same worker without music.

  2. If we pick at random a worker in Plant A, we have no information that would allow us to match that worker to another worker in Plant B. Hence we would treat these as independent samples.

  3. A woman's weight before using the diet is paired with a weight for the same woman after the diet.

  4. As it says, litter-mates are paired. Some hog farmers question whether this is a worthwhile pairing.

  5. If we pick at random a plot treated with the new fertilizer, we have no information that would allow us to match that plot with one of the plots where the old fertilizer was used. Hence we would treat these as independent samples.

  6. We would like to pair teachers with the same degrees, years of experience, publications, etc., but this is usually impossible and we have no choice but to take independent samples.

  7. This is called a split plot design. The results obtained on one half of the plot are paired with the results obtained on the other half of the same plot.

  8. The time it takes one individual to do a particular calculation on one calculator is paired with the time it took the same person to do the same calculation on the other calculator.
