Statistics is a set of mathematical techniques used to summarize research data and determine whether the data supports a proposed hypothesis. SPSS Statistics includes tools that can be used to analyze variables and determine the strength and nature of the relationship between two variables and whether the means (averages) of two data sets (samples) are statistically the same or different
In this module, we will look at correlations. A correlation is a statistical device that measures the strength or degree of a supposed linear association between two or more variables. One of the more common measures used is the Pearson correlation, which estimates a relationship between two interval variables. Created by the ITS Training Program at CSULA for students.
