If 5, 8, 6 and 2 occur with frequencies 3, 2, 4 and 1 respectively, find the product of the modal and medial number.
Answer Details
To find the modal and medial numbers from the given frequency distribution, we need to first determine the mode and median of the dataset.
The mode is the number that occurs most frequently, and the median is the middle number when the data is arranged in order.
In this case, the mode is 6, which occurs with a frequency of 4. The median can be found by arranging the numbers in order:
2, 5, 5, 5, 6, 6, 6, 6, 8, 8
The median is the middle number, which is also 6.
Therefore, the modal number is 6, and the medial number is also 6. The product of the modal and medial numbers is:
6 × 6 = 36
Therefore, the answer is 36.
