question 24
netflixs and amazons ability to suggest books and movies you might like is based on algorithms that show:
select one
a. closeness of fit
b. correlation
c. regression analysis
d. standard derivatives
e. none of the above

Explanation:

Netflix and Amazon's recommendation algorithms analyze relationships between user - preferences and item - features. Correlation measures the linear relationship between variables. These algorithms use correlation to find patterns in user behavior and item characteristics to make recommendations. Closeness of fit is more about how well a model fits data in regression. Regression analysis is for predicting a variable based on others. Standard derivatives are from calculus and not relevant here.

Answer:

B. Correlation
