The median is described as the numeric value separating the higher half of a sample, a population, or a probability distribution, from the lower half.
The median can be used as a measure of location when a distribution is skewed, when end-values are not known, or when one requires reduced importance to be attached to outliers, e.g., because they may be measurement errors.  Just remember the following: mean: regular meaning of average median: middle value mode: most often. (In the above, I've used the term average rather casually. The technical definition of average is the arithmetic mean: adding up the values and then dividing by the number of values. But there is no middle number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values: (2 + 4) ÷ 2 = 6 ÷ 2 = 3. The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode. Mode simply means the most common value in a group or a sequence. Median is the middle number, make sure they are in order before you work the median. If you have 2 middle numbers, add them up and then divide by 2 to get your median number. Mean, or Average, simply means the average number in a group of numbers.  The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first. The mode is the value that occurs most often. If no number is repeated, then there is no mode for the list. The range is just the difference between the largest and smallest values. But there is no middle number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values: (2 + 4) ÷ 2 = 6 ÷ 2 = 3. The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode. Definition. The mean is the arithmetic average of a set of numbers, or distribution. The median is described as the numeric value separating the higher half of a sample, a population, or a probability distribution, from the lower half. Applicability. The mean is used for normal distributions.  In math, median is used to refer to the middle number in a group. To determine the median, you order the numbers from (lowest) to (highest) and find the middle number in the s … eries. If there are two middle numbers, then add them together and divide by two to find the mean. Where there is an odd number of values, the median is the central (middle) value. For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the mean, which is the average value found by adding the numbers and dividing. Where there is an odd number of values, the median is the central (middle) value. For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. We use statistics such as the mean, median and mode to obtain information about a population from our sample set of observed values. The median of a set of data values is the middle value of the data set when it has been arranged in ascending order. That is, from the smallest value to the highest value. The mode of a set of data values is the value(s) that occurs most often. 1 The median may be more useful than the mean when there are extreme values in the data set as it is not affected by the extreme values. 2  The mode is useful when the most common item, characteristic or value of a data set is required. The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the mean, which is the average value found by addi … ng the numbers and dividing. Where there is an odd number of values, the median is the central (middle) value. For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. The term measures of central tendency refers to finding the mean, median and mode. Mean: Average. The sum of a set of data divided by the number of data. (Do not round your answer unless directed to do so.) Median: The middle value, or the mean of the middle two values, when the data is arranged in numerical order.
