Can you help with this assignment? Thank you.

The Internet has become an outlet not just for information but for social relationships as well. It is well known that being ostracized from a group has negative consequences for a person. Imagine that you are interested in studying whether the manner in which a person is treated during a social interaction on the Internet affects his or her mood or self-esteem. You design an experiment to test the idea that individuals who are ostracized in an Internet social interaction will show poorer mood and lower self-esteem than those who are accepted.

1. State the alternative and null hypothesis. H1 and Ho.
2. Identify the most appropriateexperimentaldesign (e.g., single-factor or factorial) and explain how exactly it qualifies as that type of design.
3. Specify precisely what the independent variable(s) will be, and how they will be manipulated. Also, specify the number of levels of each independent variable if appropriate.
4. Specify exactly what the dependent variable(s) will be, and the operational definition for the variable as well as how it will be quantified.
5. Specify the procedures that will be followed (e.g., how participants will be obtained, where the experiment will be run, and what exactly will take place). This should be detailed enough to clearly illustrate what the manipulation is in the experiment and exactly how the experiment would work.
6. Indicate what, if anything, would be done to control extraneous variables and eliminate confounding variables.
7. Indicate if the experiment could be run as a within-subjects or matched-groups design. If so, what would the matching variables be and why? For within-subjects designs, indicate what you would do to address the problems of carryover effects, participant fatigue, habituation, etc.
