No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
20.37 is the mean.
8+9+12+18+23/5=14
23 times 14 = 322

Mean is an average of a list of numbers. Median is the middle of a list of numbers. Mode is the most common number in a list of numbers. Ex. 14 17 23 48 54, the Median would be 23, the mean would be 31.2, and the mode would be undefined. The mean, median, and mode are all measures of center for a data set. A measure of center is one way to get a single result that represents all of your data for a definitive answer to a math or science question. Mode is the number that shows up most in the data set. Mean (also known as average) is found after all the numbers in a data set are added together, and that sum is divided by how many numbers in the data set there are. Median is the number in the exact middle of the data set once the data set is put in the order of least to greatest value. If the number of numbers in the data set is even, and there are two medians, then you would find the mean of the median to get your true median. Here is an example. data set: 0,0,3, 4, 5,5,5, 66, 78, 80, 90, 99,99,99,99, 106 mode:99 median: 72 mean:48
If you mean 14 plus 23, the result is 14 + 23 = 37.
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (14, 16, 16, 20, 21, 23) The median is 18. In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode. Ex. (14, 16, 16, 20, 21, 23) The mode is 16. In any given set, the range is the smallest number subtracted from the largest number. Ex. (14, 16, 16, 20, 21, 23) 23 - 14 = 9 The range is 9. In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (14, 16, 16, 20, 21, 23) 14 + 16 + 16 + 20 + 21 + 23 = 110 There are 6 numbers in this set. 110/6 = 18 and 1/3 The mean is 18 and 1/3.
The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
Compute the variance (or its square root , standard deviation) of each of the data set. Set 1: standard deviation = 10.121 Set 2: standard deviation = 12.09 Set 2 shows more variation around the mean. Check the link below
12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.
20.37 is the mean.

he mean is the average of the numbers: a calculated "central" value of a set of numbers.It is easy to calculate: Just add up all the numbers, then divide by how many numbers there are.Example: what is the mean of 2, 7 and 9?Add the numbers: 2 + 7 + 9 = 18Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6So the Mean is 6The Median is the "middle number"To find the Median, place the numbers you are given in value order and find the middle numberLook at these numbers:3, 13, 7, 5, 21, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29If we put those numbers in order we have:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56There are fifteen numbers. Our middle number will be the eighth number:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56The median value of this set of numbers is 23.
