"These are much deeper waters than I had thought.”-Sherlock Holmes Week 3: Get your feet wet. Design, Probability, Sampling CA 517 Unit 3
What is an operational definition? • Observable. • Measurable. • See for example, last week’s rubric as a way of definiting items so they are observable and measurable. • http://www.jamescmccroskey.com/measures/ • Interpersonal attraction is defined as the score on the McCroskey and McCain Measures of Interpersonal Attraction. See McCroskey, J. C., & McCain, T. A. (1974). The measurement of interpersonal attraction. Speech Monographs, 41, 261-266.

For next week, design a quantitative study • Content Analysis • Survey • Experiment CA 517 Unit 3
Example Content Analysis • Comparison of content communicated in magazine soft drink and cigarette ads. • The use of compliance gaining strategies in the movie Mean Girls. CA 517 Unit 3
Method • Describe the design: • the experimental, content analysis, or survey method, • including the apparatus, • data-gathering procedures, • complete test names, • description of the artifacts, participants or subjects, • and sampling. CA 517 Unit 3
Method • The questionnaire or apparatus (or materials) and their function in the experiment, content analysis, or survey. CA 517 Unit 3
Method • The procedure (experimental manipulations, randomization, control features in the design). • In content analysis, what are the categories of analysis? • In survey, how will you recruit participants, what will you ask, will you use interview, questionnaire, focus groups? • Summarize or paraphrase instructions. • Tell the reader what you will do and how you will do it in sufficient detail so that a read could reasonably replicate your study. CA 517 Unit 3
Probability • Kindergartners and philosophers can study probability. • It is dull; it is interesting. CA 517 Unit 3
Laws of chance • Gain knowledge from ignorance if we view randomness as ignorance. • Random events, in the whole, occur in lawful ways with monotonous regularity. • Try rolling number cubes. "Nothing clears up a case so much as stating it to another person.” –Sherlock Holmes CA 517 Unit 3
Why? • Scientists agree that if two dice are thrown a number of times, there will probably be more 7s than 2s or 12s. • They will also agree that certain events like finding a $100 bill or winning a sweepstakes are extremely unlikely. CA 517 Unit 3
Regarding People • Chance events tend to distribute themselves in the form of a normal curve. CA 517 Unit 3
