One method to calculate a 95% confidence interval is: to sample, with replacement, from the original variable and calculate the statistic; to repeat this thousands of times; and to take the middle 95% of these replicate statistics. This is called:
A) ANOVA.
B) bootstrapping.
C) correlation.
D) Efronian super-inference.

Quizplus · Accepted Answer

The method described is known as bootstrapping, which is a non-parametric resampling technique used to estimate the sampling distribution of an estimator. It allows for the calculation of confidence intervals without making assumptions about the population distribution or the underlying sampling distribution. ANOVA is a parametric statistical technique used to test differences among means, correlation measures the strength of a linear relationship between two variables, and Efronian super-inference is not a commonly used statistical term.
