www.discoveringstatistics.comTwo-Way Independent ANOVA Using SPSS Inputting Data ® Levels of between group variables go in a single column of the SPSS data editor. Applying the rule above to the data we have here we are going to need to create 2 different coding variables (seeField, 2013, Chapter 3) in the data editor.
Statistical Analysis 8: Two-way analysis of variance (ANOVA)
www.statstutor.ac.uk4 The ANOVA table gives F statistics = 7.91, p=0.002; 28.97, p<0.001 and 3.56, p=0.019, for material, operating temperature and material*temperature, respectively [NEVER write p = 0.000].So, both material and temperature are needed, as well as their interaction, to explain battery life. The nature of these differences can be explored further by looking at the SPSS …
