What name is given to the number occurring most often in a list of numbers?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

The mean, mode, median and range are averages, which are used in statistics to give information about a set of data. The mean, median, mode and range are defined as:

Mean: the average, which is found by adding up all the values in a set of data and dividing it by the total number of values you added together.

Example: The mean of 4, 1, and 7 is (4+1+7)/3 = 12/3 = 4

Median: the middle number in the set of values. You find it by putting the numbers in order from the smallest to largest and covering up one number on each end until you get to the middle.

Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1, 4, 7), the number 4 is in the middle.

Mode: the number or value, which appears most often in the set. To find the mode, you need to count how many times each value appears.

Example: The mode of (4, 2, 4, 3, 2, 2) is 2 because it occurs three times, which is more than any other number.

Range: the difference between the lowest and the highest value. To work it out, simply subtract the lowest value from the highest.

Example: The range of 4, 1, and 7 is 6 because you subtract the lowest number 1 from the highest number 7.
