However, in this “quick start” guide, we focus only on the four main tables you need to understand your one-way MANOVA results, assuming that your data has already met the nine assumptions required for a one-way MANOVA to give you a valid result.

## Descriptive Statistics

The first important one is the **Descriptive Statistics** table shown below. This table is very useful as it provides the mean and standard deviation for the two different dependent variables, which have been split by the independent variable. In addition, the table provides “Total” rows, which allows means and standard deviations for groups only split by the dependent variable to be known.

## Multivariate Tests

The **Multivariate Tests** table is where we find the actual result of the one-way MANOVA. You need to look at the second Effect, labelled “**School**“, and the Wilks’ Lambda

(highlighted in red). To determine whether the one-way MANOVA was statistically significant you need to look at the “**Sig.**” column. We can see from the table that we have a “**Sig.**” value of .000, which means *p* < .0005. Therefore, we can conclude that this school’s pupils academic performance was significantly dependent on which prior school they had attended (*p* < .0005). (output interpretation for one-way manova in spss)

## Reporting the Result (without follow-up tests)

You could report the result of this test as follows:

- General

There was a statistically significant difference in academic performance based on a pupil’s prior school , *F* (4, 112) = 13.74, *p* < .0005; Wilk’s Λ = 0.450, partial η^{2} = .33.

If you had not achieved a statistically significant result, you would not perform any further follow-up tests. However, as our case shows that we did, we will continue with further tests. (output interpretation for one-way manova in spss)

## Univariate ANOVAs (output interpretation for one-way manova in spss)

To determine how the dependent variables differ for the independent variable, we need to look at the **Tests of Between-Subjects Effects** table (highlighted in red):

We can see from this table that prior schooling has a statistically significant effect on both English (*F* (2, 57) = 18.11; *p* < .0005; partial η^{2} = .39) and Maths scores (*F* (2, 57) = 14.30; *p* < .0005; partial η^{2} = .33). It is important to note that you should make an alpha correction to account for multiple ANOVAs being run, such as a Bonferroni correction. As such, in this case, we accept statistical significance at *p* < .025. (output interpretation for one-way manova in spss)

###### SPSS Statistics

## Multiple Comparisons

We can follow up these significant ANOVAs with Tukey’s HSD post-hoc tests, as shown below in the **Multiple Comparisons** table:

The table above shows that for mean scores for English were statistically significantly different between School A and School B (*p* < .0005), and School A and School C (*p* < .0005), but not between School B and School C (*p* = .897). Mean maths scores were statistically significantly different between School A and School C (*p* < .0005), and School B and School C (*p* = .001), but not between School A and School B (*p* = .443). These differences can be easily visualised by the plots generated by this procedure, as shown below:
