Question of the Day

Answer today's PRAXIS Core Math (5733) question, reveal the full explanation, then keep the streak going with a new question every day.

The box plot below summarizes the test scores of a class of 20 students. Refer to the box plot shown. Which of the following statements must be true?

  1. The mean of the scores is 7676.
  2. The median of the scores is 7676. (correct answer)
  3. The range of the scores is 7676.
  4. Exactly 1010 students scored above 7676.

Explanation: A box plot shows the median as the line inside the box, which is 76. The mean cannot be determined from a box plot alone (A is wrong). The range is max − min = 95 − 55 = 40, not 76 (C wrong). With 20 students, the median splits data into two halves of 10 each, but students exactly at 76 could be in either half; we cannot say exactly 10 are strictly above 76 (D wrong).
