STUDY GUIDE II – SOCI 3600 1) In indexes and scales you are using multiple questions so this can provide you a better measure, single indicators only use a single question to measure a complex concept, it does not tap all the dimensions of a conceot or provide an adequate measure of the concept's intensity. 2) In indexes, all items are given the same weight, scales weigh item differently. Indexes tend to throw away some info during date reduction whereas scales preserve the info. 3) 1-Item analysis- an assessment of whether each of the items included in the measure make an independent contribution or merely duplicates the contribution of other items in the measure. 2-external validation- examines the relationship to other, presumed indicators of the same variable 3- dont know 3rd reason, I cant find it 4) It is better to use Thurstone scaling technique rather than your own because you are relying on the options of experts, and it also minimizes personal bias. Likert is good to use because it is fresh, free, quick, and it is fresh because they are always calculating weights. 5) 5Taking probability samples in 3 steps • Identify target population o UGA students who attend football games • Get a sampling frame= a list of all the people in your target population o UGA roster of students • Select respondent systematically from your sampling frame o Take a random sample of students and ask if they watched the last football game (I am not quite sure if this is the right way to do this???) A probability sample of people attending UGA football games would entail: taking every 40th person, starting at a random point amongst the first 10 individuals. Because Sanford Stadium holds 92, 746 seats, this would give you approximately 2319 people. 6) 6. Three advantages of probability samples • reduces bias • allows you to generalize from sample to the target population • you can estimate the accuracy of your results Advantages of using a probability sample: A. A researcher is better able to avoid conscious and unconscious sampling bias B. Probability samples are more representative than non-probability convenience samples. C. Random selection is more likely to come out of a probability sample. D. Probability samples allow a researcher to have a stronger confidence

level and a stronger confidence interval. 7) (I am not sure if this is right either) Because it might be hard to come up with a sampling frame and randomly sample participants Researchers do not always use probability samples because A. Reliance on available subjects. This occurs when graduate students rely on classes of undergraduate students to gather their data. B. Judgmental sampling. This occurs when the researcher intentionally selects the units to be observed based on what he or she wants to gather information about. C. Snowball sampling. This is utilized when members of a certain
