Simplified One Sample T-Test

This function simplifies the call for the one sample t-test (os.t) on a given data frame.

Usage

os.t(df, var1, mu)

Arguments

df

data frame to read in.

var1

the dependent/outcome variable, \(Y\).

mu

the population mean, \(\mu\).

Value

This function returns the summary results table for an one sample t-test, examining the mean differences between var1 (in data frame df) and the population mean mu.

Examples

data <- mtcars

ttest <- os.t(data,mpg,3)
summary(ttest)

#> os.t(df = data, var1 = mpg, mu = 3)
