(Outcome) |> describeMoments()

Obtaining Inferential Statistics

Get the mean difference and its confidence interval. Though the confidence interval defaults to 95%, it can be changed if desired.

(Outcome) |> estimateMeans(mu = 7)
(Outcome) |> estimateMeans(mu = 7, conf.level = .99)

Test the mean difference for statistical significance.

(Outcome) |> testMeans(mu = 7)

Get the standardized effect size for the mean difference.

(Outcome) |> standardizeMeans(mu = 7)
