Mean, Median and Mode - Application

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.

Add the numbers: 8.9 + 9.4 + 8.6 + 9.1 = 35. Then divide by 4 (the number of values): 35 / 4 = 8.75.

The median is the middle value of a data set when the numbers are arranged in order. If there is an even number of values, the median is the average of the two middle numbers.

Arrange the numbers in order: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. The median is the average of the 5th and 6th values: (50 + 60) / 2 = 55.

The mode is the number that appears most frequently in a data set.

The mode is Blue, as it appears most frequently (4 times).

Add the numbers: 1 + 0 + 1 + 5 + 0 + 3 + 4 = 14. Then divide by 7 (the number of values): 14 / 7 = 2.

Add the numbers: 9 + 9 + 3 + 2 + 8 + 7 + 4 = 42. Then divide by 7: 42 / 7 = 6.

Mean is the average, median is the middle value, and mode is the most frequent value in a data set.

If there are no repeating numbers, the data set has no mode.
