No.
There is only 1 middle value.
If there are an odd number of elements in the data set, the median is the middle one;
Otherwise there are an even number of elements in the data set and the median is the mean average of the middle two (add them together and divide by 2).
The median value can occur more than once in the data set, eg in {2, 5, 5, 5, 6, 7} the median is 5 ((5 + 5)/2 = 5) with a frequency of 3, but it is still only one value.

Can there be more than one median to a number?
No and a single number cannot have a median either you need a series (at least two) to have a median.
If the mean of a set of data is 23 must 23 be one of the data values?
No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
What is the median of 23 24 26 29?
Median is the middle number in a group of numbers. If there more than one middle number, the median is either shown as average of the two numbers in the middle or shown as both the numbers. The median in 23 24 26 29 is 25 or {24;26}.
What data set can have a mean of 9 and a median of 7?
There are infinitely many possible sets. One such is {6,7,14}
When should you use the median of a set of data?
The median of a set of data is used for similar purposes as the mean. They both give you a middle number that represents what the set of data fluctuates around. While the mean gives you the exact center, the median simply gives you the middle piece of data. The following is an example of why the median is sometimes more helpful than the mean: Consider a class of 5 students that take a test that is scored on a scale of 0 to 500. The scores of the students are as follows: 1) 25 2) 120 3) 102 4) 248 5) 500 The mean of the scores is (25+120+102+248+500)/5 = 199 The median of the scores is 120 Looking only at the mean, the teacher may get the impression that the students are more skilled than they really are, since the average score of the class is 40% of the highest possible score. However, one student scored only 49 points higher than the mean and the other 3 didn't get within 70 points of it. Looking at the median, the teacher sees that another accurate representation of the scores is 120. This is only 24% of the highest possible grade and better represents what most of the class got. Unlike the mean, the median wasn't set deceivingly high by the one student with a perfect score.
Median of a data is 20 If each is obesrvation in the data is increased by 2 then what is the new median?
the new median is the same as that of old one. i.e 20 * * * * * If every observation is increased by 2, the new median is 2 more than the old median.
If you have more than one median what do you do?
If you have an even set of data then there are two middle numbers or medians. Average those two and create a median. Example: 2,3,4,7,9,10 4 and 7 are in the middle. (4+7)/2=5.5 5.5 is the median even though it is not one of the numbers in the data set.
The median score on a test is 90 is it possible to add two more scores to the data and still have a median score of 90 explain?
180
Can a mean average ever be higher than a median average?
Yes. If the predominant data are higher than the median, the mean average will be higher than the median average. For example, the median average of the numbers one through ten is five. The mean average is five and one-half.
A single, extremely large value can affect the median more than the mean?
A single, extremely large value can affect the median more than the mean because One-half of all the data values will fall above the mode, and one-half will fall below the mode. In a data set, the mode will always be unique. The range and midrange are both measures of variation.
What do you do if theres two median and one is x?
One set of data can have only one median.
Can there be more than one median to a number?
No and a single number cannot have a median either you need a series (at least two) to have a median.
What is the median of two and one half?
The median of a data set comprising only one value is that value. So the median of 2.5 is 2.5.
Does all statistical data have a mean median or mode?
It depends on the definition of mode. If mode is simply the most frequently occurring outcome and more than one outcome in the sample space is allowed to be the mode, then all datasets do have a mean, median, and mode.
What is the median of 14?
With just one data point, the mean, median and mode are all the same as the data point itself. In this case, 14.
Can the mode and median for a data set be the same or different?
mode-the most (highest # in a set of data) median-the middle # when you put a set of data in order from least to greatest let's take for example a reasonable set of 10,3,4,5,7,5,9 3,4,5,5,7,9,10 3,4,5,5,7,9,10 and than your mode 5 because there was two 5's so YES IT IS POSSIBLE TO HAVE THE SAME MEDIAN AND MODE FOR ONE SET OF DATA DEPENDING ON WHAT THAT SET OF DATA IS
Is the median more affected by errors in data than the mean?
well, they're both affected. you will get both answers wrong if you make a mistake so it doesnt matter which one is more important, just pay attention
