Accuracy - correct answer Refers to a measurement giving the actual value for a sample with a limited deviation; example: determining the weight of a sample to be 1g plus or minus 0.001g Precision - correct answer Repeatability of a set of measurements, and getting very close values to each other. Test tubes - correct answer small tubes that allow a large number of samples to be arrayed in a rack for easy processing. Beakers - correct answer Wide-mouthed cylinders with a lip to allow po...

CHAPTER 3 – MOVING FROM FACT TO TRUTH: VALIDITY, RELIABILITY, AND MEASUREMENT Chapter Summary This chapter began by describing four forms of validity (internal, external, construct and conceptual). We reviewed important distinctions between these four forms of validity, but the primary point to remember is that each of the four forms of validity has to do with a different form of psychological accuracy or “truth.” Am I correct in inferring causality from a correlation (internal validity)...

aristotle's 4 causes - correct answer material, formal (form it is arranged in), efficient (mover) & final (purpose). Determinism - correct answer the belief that all events are caused by things that happened before them and that people have no real ability to make choices or control what happens Indeterminism - correct answer a theory that the will is free and that deliberate choice and actions are not determined by or predictable from antecedent causes Soft determinism - correct answ...
