LSSGB: Which of the following would be used in determining a process average fraction defective using inductive or inferential statistics?

OPTIONS

• Statistics, computed from samples, to make inferences about populations
• Populations, computed from samples, to make inferences about populations
• Samples, computed from statistics, to make inferences about populations
• Samples, computed from populations, to make inferences about samples

ANSWER

Statistics, computed from samples, to make inferences about populations

EXPLANATION

In inferential statistics, one is always making inferences about populations. Thus, option d is eliminated. From the wording of the question, statistics computed from samples is a more logical choice.
