Running the SPSS program will provide you with results in the form of tables. There are different tables produced by this program. There are two analyses involved here. One is the one-way ANOVA analysis and the other is the two-way ANOVA analysis. This article provides SPSS help which will be very useful in providing guidance in the usage of the program and in interpreting the ANOVA results generated by the program.
ANOVA Results in Analysis
In one-way ANOVA analysis, the SPSS program generates only a few tables. The tables produced include descriptive table, homogeneity of variance table, ANOVA table, robust tests of equality of means table, and multiple comparisons table.
In a two-way ANOVA analysis, the SPSS program is able to generate more tables. The additional tables it produces include Levene’s test of equality of error variances table, tests of between-subjects effects table, and univariate tests table. Interpreting these tables will be quite difficult if you have no previous knowledge of the program. That is why it is important that you read through this SPSS help article.
SPSS Help on ANOVA Table
Focusing on the ANOVA table generated by the SPSS program, this table provides the results of the ANOVA analysis. This shows whether the group means have statistically significant difference. A significance level below 0.05 means that there is a statistically significant difference between the group means. On the other hand, a significance level above 0.05 shows that there is no statistically significant difference between the group means. The limitation of this is that it cannot give the specific groups that differed. This is where the importance of the Multiple Comparisons Table generated by the program.
SPSS Help on Multiple Comparisons Table
This table shows the groups that have difference from each other and groups that do not have significant difference from one another. When the significance values of the groups are the same, this means that there is no statistically significant difference between the two groups.
Topics regarding other matters on spss analysis will be discussed in other articles. If you want to have further knowledge in using the program then continue reading SPSS help articles. An example of additional information that you can learn is about the calculation of effect size in your mode of analysis.
