• Panda image needs reformatting

• Formatting issues:

  • pop_var <- mean((Population$size - mean(Population$size))^2)
  • Sample5 <- sample_n(Population, 5)
  • Functions would be coupled with () e.g mean() so to not confuse students with objects
  • pH <- c(7.9, 7.1, 7.0, 7.2, 7.8, 8.1, 8.0, 7.7, 7.9, 7.5)
  • my.t <- (mean(pH) - 7.5)/(sd(pH)/sqrt(length(pH)))
  • Corn <- read_csv("data/Corn.csv")
  • data_lead <- read_csv("data/Lead.csv") -> R chunk

• Use nice encouraging language: "This is simply the square root of the variance." -> Rm "simply"

• Can tables be rendered nicely withmoodlequiz/.Rmd?
  

• Broken images:

  • Q15 community garden lead contamination
  • Q18 stream farm water quality

• Instructions can be better delineated using numbered lists or bolding e.g Load the data from the file Lead.csv`

• Better section headers for each dataset/research problem?

• Image credits?

• Last info/description module can be on the same page as the Kangaroos exercise

• And you're done! Great job! Add a fun image from Allison Horst
