Flashcard 1: _____ surveys are observational studies that compare a frequency of disease and frequency of risk related factors at one time point
Answer: Cross-sectional
Flashcard 2: Are cohort studies useful for measuring incidence and/or prevalence? _____
Answer: Incidence
Flashcard 3: The power of a study is increased with _____ precision of measurement
Answer: increased
Flashcard 4: What is the t-test used for? (biostatistics)
Answer: Compare means of two groups.
mnemonic: Mr. T is mean.
Flashcard 5: "β" with reference to statistical error
Answer: the probability of making a Type II statistical (false negative) error
Flashcard 6: power (epidemiology)
Answer: probability of detecting a differential effect if it is actually present
Extra: power = (1-β)
