    • How do univariate and multivariate statistics differ? - Quora

      Univariate data – Information measured on one variable. Multivariate data – Information measured on multiple variables. We are going to the look at the relationships that exist in multivariate data. Example: Cereal data (cereal_data.xls) A few years ago, I collected information on the nutritional content of dry cereal at a grocery store.

      The multivariate General Linear Model procedure (in SPSS) computes a multivariate effect size index. The multivariate effect size associated with Wilks’ Lambda (Λ) is the multivariate eta square: Multivariate η2 = Here, s is equal to the number of levels of the factor minus 1 or the number of dependent variables, whichever is smaller.

      There are more parameters to be estimated in the multivariate approach than in the univariate approach. Thus, if the assumption for univariate analysis is satisfied, one should use the univariate approach because it is more powerful. Huynh and Feldt (1970) give a weaker requirement for the validity of the univariate ANOVA F-test.

      In order to avoid biased results the data set must be checked for both univariate (outliers on one variable alone) and multivariate (outliers on a combination of variables) outliers. Four basic reasons you’d get an outlier. There was a mistake in data entry (a 6 was entered as 66, etc.), hopefully step one above would have caught all of these.
