Complete 9 page APA formatted essay: The Difference in Mean of Amount for the Two Stomach Levels.
Participants were informed that they were participating in a “taste test”. Just before the “taste test”, half the participants were given a full meal and could eat as much as they wanted, and half were not given any food at all. One hour later, a range of hors-d’oeuvres was spread out on a table in front of the participant. The participant was asked to provide a rating on a scale of 0 (yucky) to 5 (extremely delicious) for each type of hors-d’oeuvre. The experimenter then left the room so that the participant could “taste test” in private. After the participant finished their task, Schachter measured the amount of food (in grams) eaten by the participants.
The research study data had three variables namely stomach. a categorical variable with two levels (Empty and full). weight. a categorical variable with three levels (Underweight, Normal and Overweight). and amount. a continuous variable.
The data were analyzed using the statistical software SPSS and by hand calculation. ANOVA, factorial analysis, eta-squared statistic and descriptive statistics were performed. Further, post hoc test was performed to compare the mean of an amount for the different weight and stomach levels.

Further, the research should ensure that justice prevails. Research benefits should be spread out to the entire sample.

All this should be made clear to the participants before the onset of the study.
Another important part of research ethics is that the researcher should allow the participants to make an informed consent before participation. The consent should inform them of their right not to participate and to terminate their participation without penalties being imposed. . .
