Question: In addition to reliability and validity what other characteristics should
In addition to reliability and validity, what other characteristics should good quality measurements have?
Answer to relevant QuestionsHow do between-S versus within-S designs differ? Make up a list of names for imaginary participants, and use these names to show an example of between-S groups and within-S groups. Consider the following small set of scores. Each number represents the number of siblings reported by each of the N = 6 persons in the sample: X scores are: [0 1 1 1 2 7] a. Compute the mean (M) for this set of six scores. ...One way to interpret a reliability coefficient (often an r value) is as the proportion of variance in X scores that is stable across occasions of measurement. Why do we interpret r (rather than r2) as the proportion of ...When you compute difference scores (for a paired samples t test), what happens to the parts of scores that are associated with stable individual differences among persons? (In the models in this chapter, these parts of ...Table 21.7 (adapted from Pampel, 2000) shows how values of pi are related to values of odds and values of the logit Li. To do this exercise, you will either need a calculator that has the natural log function or you can find ...
