The median is the middle number of a 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. 10, 17, 20, 45, 68

The median is 20.

The mean is the average, which is the total of the numbers divided by how many numbers there are.

Ex. 10, 17, 20, 45, 68

68 + 45 + 20 + 17 + 10 = 160

There are 5 numbers in this set.

160/5 = 32

The mean is 32.

Can the mean be smaller than the median for a set of data?

Yes. If the lower values tend to be farther below the median than the highest values are above the median, the mean is smaller than the median. why are write wrong


Is the mean and median similar?

The Mean is the average of a given set of values. The Median is the value that has the same number of smaller values than the number of higher values, it is in the middle of them. In a symmetrical distribution the Mean is equal to the Median. In an asymmetrical distribution they have different value.

If it is symmetric, the median is the same as the mean.


Multiple values for the same set of numbers mean median or mode?

Any set of numbers can have only one mean and only one median but it can have as many modes as it has values.


Can the median ever be higher than the mean?

Yes, the median can be greater than the mean. It just depends on the values of the data. A simple series of 1,5,6 has 5 as the median, with a mean of 4.


What does mean and median in math mean?

What does the math term median mean?

It is the value of all numbers in the range in which there are as many values above it as there are below it. For example for the ordered values 1,3,7,9,10,12,15,19,21 the median value is 10. It is not he same as the mean, or average, which is the sum divided by the number of values.


You are trying to do a mean problem but you have 2 numbers in the middle what do you do?

You may be confusing mean with median. An arithmetic mean is, the sum of all the values ÷ the number of values. Consequently the number of values can be either odd or even. After arranging a set of values in ascending (or descending) order, the median is the value that lies half way along the series. When there are an even number of values the median is found by taking the mean of the middle two values. Example : 3, 5, 5, 7, 8, 8 The median of this set is (5 + 7) ÷ 2 = 6


What is generally correct about the relation between the mode median and mean?

Of a set of data the mode is the most, the median is the middle value in ascending order and the mean is the sum of the values divided by the number of values.


Why calculate for the mean and median in relation to a sample?

Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.

Compare and contrast mode mean and median?

Mean = average formed by adding values together and dividing by the total number of values Mode = the most popular value Median = line up all values in order and take the middle value


Why is the median a more stable measure of central tendency than the mean?

in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.


In any data set are the median and mean usually very similar in value?

yes they are if you have 0 and 10 the mean is 5 and so is the median. The mean and the median can in fact be the same value. But basically to answer your question, One possible way is that if the values are ascending by 1 in the data set, then the number of values left to the median should be the same as the number of values right to the median. e.g. 6+7+8+9+10 6,7 = 2 terms 9,10 = 2 terms median =8 mode = 8


What does median mean in math?

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. (if you have duplicate values, more than one may be equal to the median)Where there is an even number of values, the median is the mean (average) of the two central values. For example, in the set [ 1, 2, 7, 9, 50, 100 ], there are two central values, 7 and 9. The median would be 8, and again there will be as many values less than the median as there are greater than the median.To find the median : put your numbers in order by their value, and count the number of values. Divide the number of values by two to locate the center value or values. Where the number of values is even, add and average the two in the middle.Example : values [ 27, 18, 3, 99, 55, 1, 16 ]Ordered set : [ 1, 3, 16, 18, 27, 55, 99 ]Median : 18* (See the related link for more on this)The median is the central value in an ordered list of numbers. If there is an even number of numbers in the set, the median is the average of the middle two.Median in math is a term that is used when you are looking for the mid point.


Is the mean and median the same?

No, they are both averages but worked out in different ways and give different answers. The mean is the sum of all the values added together and then divided by the number of values there are. The median is found by arranging the values in numerical order and finding the number in the middle.


What does range mean median mode mean?

Range, Mean, Median, and Mode all relate to a set of values. To find the range of the set, subtract the smallest value from the largest value . To find the mean, add all the values together and divide by the total number of values in the set. To find the median, sort the values from smallest to greatest, and find the value that is in the middle of the sorted list. To find the mode, simply find the value or values in the set that appear the most often.


What is the math median mean?

The MEDIAN is the number in the middle. In order to find the median, you have to put the values in order from lowest to highest, then find the number that is exactly in the middle. For example : 80 85 90 90 90 100 ^ since there is an even number of values, the MEDIAN is between these two, or it is 90. Notice that there is exactly the same number of values above the median as below it! Its that simple.

Do extreme values affect the median?

No they do not (or at least they have less of a significant impact) and this is the benefit of using the median average over the mean average.


Median of a data is 20 If each is obesrvation in the data is increased by 2 then what is the new median. Need descriptive answer?

The median of a set of values or data is the value which lies half-way along the series when it is arranged in ascending or descending order. If there are an even number of data entries then the median is the mean of the middle two values. 1) If there are an odd number of values then there will be the same number of values higher than the median as there are below the median. An increase of 2 to each member of the set does not affect the order and the existing median remains the middle placed value So, 20 becomes 22. 2) Where there are an even number of values then both middle values will increase by 2 (a total increase of 4). The median is the mean of these two values and therefore increases by 2 (as the increase of 4 ÷ 2 = 2). So, 20 becomes 22.
