About

This page documents the process of importing, cleaning, and visualizing the data about student presentation preferences. The page then goes on to show how student presenters and discussants were assigned to readings by date and student preference.

Set up

We load some critical packages.

Code 
suppressPackageStartupMessages(library(ggplot2))
suppressPackageStartupMessages(library(dplyr))
suppressPackageStartupMessages(library(tidyr))
suppressPackageStartupMessages(library(googlesheets4))

Acquire

We acquire the survey data from a Google sheet generated by the survey form, then save it as as CSV.

Code 
if (params$reimport) {
  if (!dir.exists(params$csv_dir)) {
    message("Creating missing `include/csv/`.")
    dir.create(params$csv_dir)
  }
  
  options(gargle_oauth_email = Sys.getenv("GMAIL_SURVEY"))
  googledrive::drive_auth()
  
  student_ratings <- read_sheet(
    "https://docs.google.com/spreadsheets/d/17kvNbyOj1SYjyasxgpo6vDZce1sL4lwqqeAbRCWJJEE/edit?gid=526883845#gid=526883845"
  ) |>
    readr::write_csv(file.path(params$csv_dir, params$data_csv_fn))
}

Clean

We reimport the saved CSV file and clean it.

Code 
ratings <- readr::read_csv(file.path(params$csv_dir, params$data_csv_fn),
                                 show_col_types = FALSE)

[18] "P: Poverty can be adaptive for cognition"

We want to capture the “raw” or full question name and the short variable name in a data dictionary.

Table 1: A minimal data dictionary.

student_info <- readr::read_csv(file.path(params$csv_dir, "student_data.csv"),
                                 show_col_types = FALSE)

# Add a student index variable
ratings_clean <- ratings_clean |>
  mutate(student_i = 1:length(timestamp))

ratings_clean <- left_join(ratings_clean, student_info, by = 'email')

ratings_short <- names(ratings_clean)

Visualize

Let’s look at ratings by topic to see if we have reasonable variation.

To do this, we need to incorporate the rating_* columns as row variables.

Code 
ratings_long <- ratings_clean |>
  tidyr::pivot_longer(cols = c(3:18), names_to = "topic", values_to = "rating")
Code 
ratings_long |>
  ggplot() +
  aes(x = rating) +
  geom_histogram() +
  facet_wrap(~ topic, nrow = 6, ncol = 3)
`stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
Figure 1

Let’s also look to see if we have some variation by student. We assign an anonymous code to each student first.

Code 
ratings_long |>
  ggplot() +
  aes(x = rating) +
  geom_histogram() +
  facet_wrap(~ student_i, nrow = 6, ncol = 3)
`stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
