The following research studies are either single sample, independent sample or dependent sample. Choose only one for each question: with a short explanation why.
1. Two groups were exposed to different levels of treatments of ankle sprains. Which treatment was most effective?
1. A researcher in nursing wanted to know if the recovery of patients was quicker when some received additional in-home care whereas others received the standard amount.

1. A group of adult men was given different instructions than last year in reducing their high blood pressure. The amount the blood pressure was reduced last year by 50. Are this year’s methods better or worse than last year’s at reducing blood pressure?
1. One group of men was provided access to an exercise program and tested two times over a 6-month period or heart health.

Expert Solution

(a)

Correct option:

Independent Samples

EXPLANATION: Here the two groups are treated with different levels of ankle sprains. The two samples are independent.

(b)

Correct option:

Independent Samples

EXPLANATION: Here the two groups are: Group 1: Additional home car. Group 2: Standard amount. The two samples are independent.

(c)

Correct option:

Dependent Samples

EXPLANATION: Here the same group is measured twice: September and May: The two samples are not independent because they are same set of .adolescent boys and thus the samples are dependent pairs.

(d)

Correct option:

Dependent Samples

EXPLANATION: Here the same group is measured twice: last year and this year: The two samples are not independent because they are same set of .adult men and thus the samples are dependent pairs.

(e)

Correct option:

Dependent Samples

EXPLANATION: Here the same group is measured two times over a 6 - month period. The two samples are not independent because they are same set of .men and thus the samples are dependent pairs.

Refresher on Variables: Classifying variables as independent or dependent: The independent variable is the one being manipulated or grouped in the study for comparison. A tip to remember this is to think that independent starts with “I” and I, the researcher, manipulate that variable or have control over who is grouped in the study. The way we will be using independent variables in this course is in terms of between group analysis, so our focus will be on groups being...
