If the mode of the data set 3, 7, 7, 2, 5, 7, 8 is x, what is the value of x?
Correct Answer: 7
  • Step 1: Look at the data set: 3, 7, 7, 2, 5, 7, 8.
  • Step 2: Identify how many times each number appears in the data set.
  • Step 3: Count the occurrences: 3 appears 1 time, 7 appears 3 times, 2 appears 1 time, 5 appears 1 time, and 8 appears 1 time.
  • Step 4: Determine which number appears the most often.
  • Step 5: Since 7 appears 3 times, and all other numbers appear less frequently, 7 is the mode.
