Getting variance despite having only one replicate?
hopefully, a quick question. I am doing some stats work in R and I am getting error bars and variance for a treatment despite it only have one rep (the other 3 had no survivors in the experiment).
Can anyone explain how that would be possible? What is R actually giving me?
If it helps, here is my code for one of my graphs:
ggplot(data = clammass, aes(x=TreatmentF, y=DryAvgMass)) + geom_point(stat = "summary")+ stat_summary(geom="errorbar", fun.data = mean_se, width = .3)+ scale_fill_brewer(palette = "Spectral")+ theme_test(base_size = 16)
