750-1000 word written project. Do the the following:
• provide a brief description of the different methods of research that are described i (single case study, observational, correlational, experimental, quasi-experimental)
• evaluate the different methods, and select one that you feel fits best with each of the three descriptions provided
• give a rationale as to why you selected the method that you did
• Describe how the research method you selected uses the scientific method
• Discuss any ethical issues that might apply when using this method
• Discuss any limitations to the conclusions that accompany your method of research

1. A researcher was able to modify the behavior of a mentally impaired eight-year-old girl. The maladaptive behavior was spoon banging during mealtime in school. The researcher measured the girl's behavior before, during and after an intervention where she was immediately given her food upon entering the cafeteria. The research was able to show that this treatment was effective in helping the girl to stop her spoon banging behavior (Horton, 1987).

2. A team of researchers studies gender differences in need for affiliation. Need for affiliation was measured by observing students entering the college cafeteria and recording whether each student was alone or with other students. Females were significantly more likely than males to be in the presence of another person when entering the cafeteria. This finding is consistent with a description of females as having a greater need for affiliation (Latane & Bidwell, 1977).

3. A researcher studies the effectiveness of two different approaches that small groups use in making decisions. The researcher randomly assigned 20 groups of two participants to use a cooperative approach and 20 groups of two people to use a competitive approach. The researcher measured the degree of satisfaction with the final decision that each group member reported after the group had reached its final decision. The members of the groups who used the cooperative approach reported more satisfaction than did those who used the competitive approach.
