Which of the following Measure of Averages is not based on all the val...
The mode is the value or values that occur most frequently in the data set. It represents the most common observation(s) or the peak of the distribution.
Unlike the arithmetic mean, geometric mean, and median, the mode does not take into account all the values in the data set. Instead, it focuses solely on identifying the value(s) with the highest frequency.
For example, consider the following data set: 2, 4, 4, 6, 6, 6, 8, 8, 8. In this case, the mode is 6 because it occurs three times, which is more frequently than any other value. The mode is determined by counting the occurrences of each value, rather than considering the entire range of values.
On the other hand:
-
The arithmetic mean is calculated by summing all the values in the data set and dividing by the total number of values. It incorporates all the values in the calculation.
-
The geometric mean is calculated by taking the nth root of the product of n values. It also considers all the values in the data set.
-
The median represents the middle value when the data set is arranged in ascending or descending order. It includes all the values and identifies the middle observation(s).
Therefore, among the options given, the measure of average that is not based on all the values given in the data set is the mode. It focuses on identifying the most frequently occurring value(s) rather than considering all the values in the data set.
