Determine a freshman's likely first-year grade point average from the student's Scholastic Aptitude Test (SAT) score, high school grade point average, and number of extra-curricular activities. This is an example of
 a. classification of a categorical outcome.
  b. estimation of a continuous outcome.
  c. prediction of a categorical outcome.
  d. unsupervised learning.

Question 2

Jaccard's coefficient is different from the matching coefficient in that the former
 a. measures overlap while the latter measures dissimilarity.
  b. does not count matching zero entries while the latter does.
  c. deals with categorical variable while the latter deals with continuous variables.
  d. is affected by the scale used to measure variables while the latter is not.

Answer to Question 1

b
RATIONALE: When we predict a freshman's first-year GPA from their SAT score, high school GPA, and number of extra-curricular activities we are using this information to estimate a continuous outcome.

Answer to Question 2

b
RATIONALE: Jaccard's coefficient refers to a measure of similarity between observations consisting solely of binary categorical variables that consider only matches of nonzero entries.
