Analyzing Likert Data

This article, authored by Harry N. Boone Jr. and Deborah A. Boone from West Virginia University, provides guidance on the correct analysis of Likert data for Extension professionals. It highlights the differences between Likert-type items and Likert scales, emphasizing that Likert-type items are single questions with Likert response alternatives, while Likert scales are composite scores derived from multiple Likert-type items. The article discusses the appropriate statistical procedures for analyzing these two types of data, noting that Likert-type items fall under the ordinal measurement scale and should be analyzed using modes, medians, and frequencies, whereas Likert scales, being composite scores, should be analyzed using means and standard deviations. The article also references various studies that have used Likert scales in Extension research and provides a table of suggested data analysis procedures for each type of data.This article, authored by Harry N.
