Question

Independent or Paired? For each scenario below determine if it is a paired data scenario or based on two independent samples. Question 1 Subquestions 1.a 0.5 point(s) A study was conducted to compare the grade point averages of juniors who live in campus dormitories with the grade point averages of juniors who live off campus. Twenty juniors were randomly selected from campus dormitories at a college, and 20 other juniors were randomly selected from students who live off campus. a Paired Data A Two Independent Samples 1.b 0.5 point(s) An experiment was performed to compare the reaction time to two types of traffic signs. One sign type is prohibitive (e.g., No Left Turn) and the other sign type is Permissive (e.g., Left Turn Only). Ten drivers were used in the study. Each driver was presented with 40 traffic signs, 20 of each type, in a random order. For all 40 signs, reaction time was recorded and the mean of each sign-type calculated. a Paired Data A Two Independent Samples 1.c 0.5 point(s) A study was conducted to evaluate the average gain in strength due to a fitness-training program. Thirteen individuals each took a strength test both before and again after they participated in a six-week fitness-training program. a Paired Data a Two Independent Samples

Explanation / Answer

Paired Test -

If the same sample is tested twice against different stimuli, then it comes under a Paired Test

Independent 2 Sample Test-

If two samples are tested against the same stimulus then it is an Independent 2 Sample Test

1 a)

We have two samples here- Juniors on campus dormitory and students off-campus and the stimulus is CGPA

So, it is a 2 Independent Samples

1 b)

The sample is one- 10 Drivers

However, the stimulus is two different traffic signals

So, it is Paired Samples

1 c)

The sample is one- 13 individuals

However, the stimulus is strength test before and after the training program

So, it is Paired Samples

Hope this helps and Please don't forget to rate the answer :)
