This tutorial demonstrates how to compute measures of central tendency (e.g., mean, median) and dispersion (e.g., standard deviation, interquartile range) in R, where these measures are common types of descriptive statistics and are useful for describing variables that have interval or ratio measurement scales. I focus on using base R functions like mean, median, var, sd, min, max, IQR, and quantile. In addition, I demonstrate how to visualize scores in a distribution using the hist (histogram) and boxplot (box plot) functions from base R.
