tadaa_one_sample: Tadaa, one-sample tests!

In tadaadata/tadaatoolbox: Helpers for Data Analysis and Presentation Focused on Undergrad Psychology

Description

If sigma is omitted, the function will just perform a one-sample stats::t.test, but if sigma is provided, a z-test is performed. It basically works the same way, except that we pretend we know the population sigma and use the normal distribution for comparison.

Usage

tadaa_one_sample(
  data = NULL,
  x,
  mu,
  sigma = NULL,
  direction = "two.sided",
  na.rm = FALSE,
  conf.level = 0.95,
  print = c("df", "console", "html", "markdown")
)

Arguments

data	A data.frame (optional).
x	A numeric vector or bare column name of data.
mu	The true mean (μ) to test for.
sigma	Population sigma. If supplied, a z-test is performed, otherwise a one-sample stats::t.test is performed.
direction	Test direction, like alternative in t.test.
na.rm	Whether to drop NA values. Default is FALSE.
conf.level	Confidence level used for power and CI, default is 0.95.
print	Print method, default df: A regular data.frame. Otherwise passed to pixiedust::sprinkle_print_method for fancyness.

Value

A data.frame by default, otherwise dust object, depending on print.

Examples

set.seed(42)
df <- data.frame(x = rnorm(n = 20, mean = 100, sd = 1))

tadaa_one_sample(df, x, mu = 101, sigma = 1)

# No data.frame, just a vector
tadaa_one_sample(x = rnorm(20), mu = 0)
