Question 1
For the show The Handmaid’s Tale (title_id
is tt5834204), there are 4 seasons listed in the IMDB database. Find the average rating of each of the four seasons. Hint: Use AVG
for find the average, and use GROUP BY
the season_number
.

Question 3
Make a dotchart in R showing the results of the previous question.
Hint: You can use your work from SQL, and export the results to a dataframe called myDF
in R. Then you can use something like:
# use a dbGetQuery here, to import the SQL results to R, and then
myresults <- myDF$rating
names(myresults) <- myDF$primary_title
dotchart(myresults)

Question 6
Among the three big New York City airports (JFK
, LGA
, EWR
), which of these airports had the worst DepDelay
(on average) in 2005? (Can you solve this with 1 line of R, using a tapply
(rather than using 3 separate lines of R)? Hint: After you run the tapply
, you can index your results using [c("JFK", "LGA", "EWR")]
to lookup all 3 airports at once.)

Question 7
LIKE
is a very powerful tool. You can read about SQLite’s version of LIKE
here. Use LIKE
to analyze the primary_title
of all IMDB titles: First determine how many titles have Batman
anywhere in the title, and then determine how many titles have Superman
anywhere in the title? Which one occurs more often?

Question 8
How much money was donated during the 2000 federal election cycle by people who have PURDUE
listed somewhere in their employer name? How much money was donated by people who have MICROSOFT
listed somewhere in their employer name? Hint: You might use the grep
or the grepl
(which is a logical grep) to solve this one.
