Key Concepts

Histogram

A histogram is a graphical representation that organizes a group of data points into user-specified ranges or bins. It shows frequency distributions of a continuous variable, making it easier to observe the underlying distribution, detect skewness, and identify outliers—all essential aspects in descriptive statistics and exploratory data analysis.

Stem-and-Leaf Display

A stem-and-leaf display is a method for presenting quantitative data in a visual format while preserving the original data values. It splits each data point into a 'stem' (typically the leading digit or digits) and a 'leaf' (the trailing digits), allowing for quick insights into the data distribution, central tendency, and variability. This tool is particularly useful for small to moderate-sized datasets.
