Options:
A) 126
B) 131.43
C) 138
D) 134

Answer :

To find the mode of a data set, we look for the number that appears most frequently. Let's examine the given data set: 126, 134, 128, 126, 138, 134, 134.

Step-by-step, let's count the frequency of each number:

  • 126 appears 2 times
  • 134 appears 3 times
  • 128 appears 1 time
  • 138 appears 1 time

The mode is the number with the highest frequency. From the counts above, we see that 134 appears 3 times, which is more frequent than any other numbers.

Therefore, the mode of the data set is 134.

The correct option is: D) 134.
