Question

Explain the difference between an independent and dependent sample. Choose the correct answer below. A. In an independent sample, the individuals are chosen without replacement; in a dependent sample, the individuals are chosen with replacement. B. In a dependent sample, one would use a two-tailed hypothesis test; in an independent sample, one would use a one-tail hypothesis test. C. A sample is independent when an individual selected for one sample does not dictate which individual is to be in the second sample. A sample is dependent when an individual selected for one sample dictates which individual is to be in the second sample. D. A sample is independent when an individual selected for one sample dictates which individual is to be in the second sample. A sample is dependent when an individual selected for one sample does not dictate which individual is to be in the second sample. Independent samples are often referred to as matched-pairs samples.

Answer 1

The answer is C

make confident decisions about their lives.

Answer 2

Dependent and Independent Samples. ... In short, when we have independent sampleswe assume that the scores of one sample do not affect the other. Independent samplescan occur in two scenarios. Testing the difference of the means between two fixed populations we test the differences between samples from each population. The answer will then be A or D. I cannot decide.
