Now that you are in the SPSS output screen, your screen should look like the following: Your first table is titled Between-Subjects Factors and it is entirely redundant with the table immediately below it. The column of n in the Between-Subjects Factors table is duplicated in the Descriptive Statistics table. Therefore, we will not use the Between-Subjects Factors table.
Focusing on the Descriptive Statistics table will show you a column for the M , for the SD , and for the sample size, n . This information has been provided to you for each of the four dependent variables for each of the three groups. This information will be used in your Results section and should be kept.
Underneath the Descriptive Statistics table is the Box’s Test of Equality of Covariance Matrices. The information in this box involves checking one of the assumptions underlying use of a MANOVA procedure. The Sig. value in this box should be greater than .05 if the assumption is met. In the example below, the Sig. value is .234 which means that this particular assumption has been met. Readers should be informed whether the Box’s M assumption was met or was violated. See Field (2010) for a detailed explanation of Box’s M and the use of a MANOVA, even when this assumption is violated.
Underneath the Box’s Test of Equality of Covariance Matrices is the Multivariate Tests table. This table is important because it indicates whether or not a statistically significant difference is present among the reading groups (i.e., our independent variable) in the aggregated dependent variable (i.e., aggregated Verbal 1 through Verbal 4). For our purposes, we will use Wilks’ Lambda to determine whether or not a difference is present. In this example, a statistically significant difference is present.
