- Read the following study:
Researchers are interested in the effectiveness of a particular treatment for insomnia. They contact 50 insomnia sufferers who responded to a newspaper advertisement to participate in the study. Each participant is given a pill with instructions to take it before going to sleep that night. The pill actually contains milk powder (a placebo). The participants are randomly assigned to receive one of two sets of instructions about the pill. One half of the participants are told that the pill will make them feel “sleepy,” and the other half are told that the pill will make them feel “awake and alert.” The next day the participants return to the lab and are asked to indicate how long it took them to fall asleep after taking the pill. The individuals who were told that the pill would make them feel sleepy reported that they fell asleep faster than the participants who were told the pill would make them feel alert.
Think about the concepts you read about this week on one-way experimental design and how they apply to the above study.
The Assignment (1–2 pages):
With the study in mind, please do the following:
- Identify the independent and dependent variables. Indicate the number of levels in the independent variable and describe each level.
- Indicate whether the research used a between-participants or a within-participants research design. Justify the rationale behind your identification.
- Presume a third condition was added to the present study. In this condition, the participants are not given any information about the effects of the (placebo) pill. Next, suppose an Analysis of Variance (ANOVA) was conducted. Briefly interpret, in your own words, what it would mean if the F was significant for this study.
