Q53 / 100
What does "na.rm = TRUE" do when passed to functions like mean() or sum()?
Correct! Well done.
Incorrect.
The correct answer is B) It excludes NA values from the calculation, so they do not cause the result to be NA
B
Correct Answer
It excludes NA values from the calculation, so they do not cause the result to be NA
Explanation
Without na.rm = TRUE, the presence of any NA in the input causes functions like sum() or mean() to return NA; setting it to TRUE ignores NAs during computation.
