Question
Identify each experiment below as an independent samples design or a paired samples design. Type in the answer at the end.
1. At a hunting club the squirrel hunters had a contest with the quail hunters to see who could hit the most moving targets.
2. A consumer-testing group compared Oxyclean and Tide to determine which got stuff whiter. Sheets that had been placed for 12 hours in a bathtub of mud were washed and the amount of light reflected was measured with a photometer.
3. Fifth-grade American Indians were matched as a group to a group of New York Puerto Ricans on SES, IQ, and reading level. They were then given a questionnaire on attitudes toward school.
4. On the basis of a pretest on knowledge of foreign governments, each student in the 9:00 class was matched with a student in the 10:30 class. The 9:00 class used a "participant approach" to the study of politics and the 10:30 class used the "Heidleburg method." At the end of the term the same test was given to both classes.
Explanation / Answer
1. Here two groups are essentially different from each other one group is hunting squirrels another is hunting quails. There is, in general, no reason to believe that two group has anything common. Thus it is an independent samples design.
2.This is also an independent samples design. Because, two detergents used for comparisons are different thus the stuffs on which they were applied would respond in different manner.
3.Again here the study groups are completely different. One is formed by fifth grade american indians and another is by new york puerto ricans. Thus, they do not have any common characteristics. Thus it is an independet sampls deisgn
4. Two classes had different approches towards the subjects,thus it is bound to be independet from each other. It is also an independent samples deisgn.
