Randomization can occur at two points in an experimental study. Design your own study, specifying whether your selection of subjects is randomized or non-randomized. Also note whether the assignment to treatment and control groups is randomized or non-randomized. What are the main characteristics of your experiment that make it either randomized or non-randomized? Be sure your example is for experimental research and not a survey, case study, or correlational design.

Subject: Experimental Psychology 2. A researcher wishes to learn whether college students use more slang when speaking with a person their own age than when speaking with an older person. Design a within-subjects experiment to test this hypothesis. Divide your responses into the following sections: 1. Research question, hypotheses, and design, 2. Participants, 3. Measures, and 4. Procedures. As a guide, be sure to include the following: a. Provide a clearly written research question, clearly state your null and alternative...
