Question 84

A table records the value 0 once, the value 1 once and the value 2 eight times. Select all statements that are true about these values and their median. Select all that apply.

  1. The fifth and sixth values in order are both 2Correct answer
  2. The median is 1, the middle of the three values named
  3. There are 3 values altogether, one for each value that is named
  4. The median is 2Correct answer
  5. The median is 1.5, halfway between 1 and 2

Explanation

In order the ten values run 0, then 1, then eight 2s, so the fifth and sixth places are both held by 2 and the median is 2. Counting only the three values named mistakes a list of labels for the data itself, and taking the middle of those labels gives 1, while eight of the ten observations equal 2 and push the central places well past the value 1.
