Practice

library(tidyverse)

Load in the data

class = read_csv("data/classData.csv")

## 
## ── Column specification ────────────────────────────────────────────────────────
## cols(
##   lab_section = col_double(),
##   local_R = col_logical(),
##   work_with = col_double(),
##   bender = col_character(),
##   predicted_score = col_double()
## )

Take a look at the data

glimpse(class)

## Rows: 88
## Columns: 5
## $ lab_section     <dbl> 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, …
## $ local_R         <lgl> TRUE, FALSE, FALSE, FALSE, FALSE, TRUE, TRUE, TRUE, FA…
## $ work_with       <dbl> 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, NA, 1, 1, 1,…
## $ bender          <chr> "Airbender", "Firebender", "Firebender", "Waterbender"…
## $ predicted_score <dbl> 89.43310, 74.27888, 71.08258, 54.80504, 59.83693, 82.3…

1. Which nation is the most represented? Least represented? Make a visualization to illustrate.

2. Are any lab sections predicted to do better than others on an airbender test? Is there a correlation between lab section and predicted score?

3. Why?

4. How could you see this on the plot above?
