It consists of a statement or a question, followed by a series of five or seven answer statements. For example, if only Pre-scores are given, or if both Pre-scores (\(x\)) and Post-Scores (\(y\)) are given and paired is TRUE (i.e., the same persons answers), a Wilcoxon signed rank test of the null that the distribution of \(x\) (in the one sample case) or of \(x\) - \(y\) (in the paired two sample case) is symmetric about \(\mu\) is performed. Stevens discussion on the analysis of interval data: Most psychological measurement aspires to create interval scales, and it sometimes succeeds. The Likert scale is easy to use and relatively clear, which provides researchers with the ability to question large sample sizes of people as well as conduct a descriptive analysis of the data. mean sd min Q1 median Q3 max When only the rank-order of the data is known, we should proceed cautiously with our statistics, and especially with the conclusions we draw from them.
