Question

Generally, the ________ sample procedure for inferences about two population means provides better precision than the _______ sample approach.​A)  ​single, independentB)  ​independent, pooled​C)  ​matched, independentD)  ​matched, pooled

Spencer Gates · Accepted Answer

Final Answer : C, Explanation :  The matched sample procedure involves pairing individuals from two populations who are similar in some way (e.g. age, gender, etc.) and comparing the means of the paired samples. This approach reduces variability and increases precision. The independent sample approach involves comparing the means of two samples that are unrelated to each other, which can lead to greater variability and less precision. Therefore, the matched sample procedure is generally preferred when possible.
