Example: ANOVA table for effect of varying CO2 concentration on biomass
of pea seedlings* * Do not include these values in your report

Here is how to present the stats values. The colours show where the values come from in the ANOVA table:
“There was a significant effect of changing CO2 concentration on pea biomass (F(1,588) = 53.73, p < 0.001; Figure
1). Biomass was significantly higher** under high CO2 compared to medium and low CO2, but biomass under low CO2
was not significantly different to biomass under medium CO2.” **note that you would see in the graph which treatment was higher
or lower compared to others, but the post-hoc test tells you if this difference between groups is significant.
