The table shows the distribution of data represented by letter x.
The mode is the one that has the highest frequency.
The letter x occurs most frequently at point 9. This means 9 occurs most frequently, OR
The Mode of the data is 9
The first option is the correct answer
Observe carefully that the axis on which the data distribution is shown is graded in twos. That is, 2, 4, 6, 8 and so on.
Observe also that the numbers have one stroke between each of them. These strokes each represent the value between each interval. The stroke between 2 and 4 is 3, and that applies to all other intervals. That is the stroke between 12 and 14 is 13, and so on.
Hence, the stroke between interval 8 and 10 is 9. You will observe that the data between 8 and 10 is the most frequent/highest. That is how we arrived at our answer
