Lean Six Sigma Green Belt (LSSGB) — Question 13

A 1-Sample t-test is used when you want to compare the Median of one distribution to a target value.

Answer options

• A. True
• B. False

Correct answer: B

Explanation

The statement is false because a 1-Sample t-test is designed to compare the mean of a distribution to a known value, not the median. For comparing medians, other statistical tests, such as the Wilcoxon signed-rank test, are more appropriate.
