A researcher has developed a set of breathing exercises and would like to investigate whether they can help to reduce anxiety.She designs an experiment as follows.She will obtain a group of volunteers suffering from anxiety.They will be given a test to measure the level of their anxiety.Volunteers will be randomly assigned to one of three groups.Those in group 1 will do breathing exercises for 15 minutes per day,those in group 2 will do breathing exercises for 30 minutes per day,and those in group 3 (control group)will do no breathing exercises.After a suitable time period,each person will again take the anxiety test.The researcher will compare the average change in score for the three groups.Is it possible to double blind this experiment? Explain.
Breathing Exercises
Techniques aimed at improving respiratory efficiency, reducing stress, and enhancing overall well-being.
Anxiety Test
A method or assessment used to evaluate the current level or intensity of an individual's anxiety, which can vary in form from questionnaires to clinical evaluations.
Double Blind
An experimental protocol where neither the participants nor the experimenters know who is receiving the treatment versus the control, eliminating bias.
- Grasp the fundamental significance of double-blinding techniques in experimental designs.
- Detect and interpret frequent pitfalls in the structuring of experiments.
