Question

For each scenario listed on the left, determine whether the scenario represents an Indepenent Samples or Matched pairs situation by placing the appropriate letter in the box provided.

• a or b? Comparing pain levels of a group receiving a placebo to a group receiving a medicine
• a or b? Comparing pre-test scores before training to post-test scores
• a or b? Comparing the number of speeding tickets received by men to the number received by women
• a or b? Comparing pain levels before and after treatment with magnetic therapy

1. Independent Samples
2. Matched Pairs

Answer 1

ANSWER:

o Given > comparing pain levels of a group receiving a placebo to a group receiving a medicine Here, we are comparing comparing two different groups each having different observations. Therefore the variables: mentioned here are independent Samples, ... Answer is an independent Samples. → comparing pretest scores before training to post- test scores Here , also we have same set of observations whose are recorded women scoves before and after the training Therefore the samples will be dependent. : Ansiver is b. matched pairs → comparing the number of speeding tickets received by men to the number received by also we have two independent groups men and women. Therefore bere also we use independent Sample test. .: Answer is is a: independent Samples.

2 → comparing pain levels before and after treatment with magnetic therapy Here, we have same set of observations whose pain level before and after the treatment are measured. That is this is a dependent Sample test. ... Answer is b. matched pairs
