No, it is not.
They're quite different.
It's not quite clear what you mean by "peak". You could be referring to the maximum; i.e. the number that's greater than or equal to every other number in the set. Alternately you could be thinking of the mode, which is the number that occurs most frequently.
Either way, they're not the same as the median. The median is the "middle number" in a set of data. That is, it divides the set into two equal groups; those in one group are less than or equal to the median and those in the other are greater than or equal to the median.
Here are some examples:
S = {1, 9, 2, 8, 4, 12, 3, 5, 8}
First, put them in order: {1, 2, 3, 4, 5, 8, 8, 9, 12}
The maximum is the largest number, 12.
The median is 5, because there are four numbers (1, 2, 3, 4) less than or equal to 5 and four numbers greater than or equal.
The mode is 8 because it occurs more often than the other numbers.
T = {1, 5, 2, 9, 4, 3, 8, 7}
Put them in order: {1, 2, 3, 4, 5, 7, 8, 9}
The maximum is 9.
The median is 4.5 - because the set has an even number of elements, the median is the average of the two middle numbers.
The set doesn't have a mode because all numbers occur only one time.
U = {1, 3, 1, 1, 1, 1, 1}
The maximum is 3
The median is 1. Even though the set has an even number of elements, 1 divides the set into a lower half {1, 1, 1, 1} and an upper half {1, 1, 1, 3}
The mode is also 1 because it's the most frequently-occurring value.

What is median in the set of data?
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
What does the median tell you about the data?
The median, by definition, tells you the "half way point" of your data. Exactly half of the observations in the dataset will be less than the median and half will be greater than the median.
Does some quantitative data sets do not have a median?
No, they must have a median. However, if the data set is of even order, the median may not belong to the data set. For example, the median of 1,2,3,10 is halfway between 2 and 3 or 2.5 which is not a data point.
Should The mean or median be used in ordinal data?
The median is used when reporting ordinal data.
Does all data have a mean median or mode?
No, not all data sets have a mode but all data sets have a mean and median.
What does the median of a set of data tell you?
The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.
What if the data doesnt have a median how do we make a box and whisker plot?
If the data are quantitative they must have a median. If there is no median it is only because the data are qualitative and, in that case, a box and whiskers plot is meaningless.
Which graphic display shows the median and data spread about the median?
A frequency diagram or, for grouped data, an histogram.
How is it possible for two sets of data to consist of different numbers but have the same mean the same median the same mode?
The range of a data set is the difference between the largest and smallest number in your set of data. Median is the number that comes in the middle. 54, 55, 56 has a range of 54-56 and a median of 55. The set 53, 55, 57 has a median of 55 also!
What is the measure of central tendency for nominal and ordinal data?
The mode can be used with both kinds of data. The median may be used with ordinal data but great care is required if the median falls between two classes of observations.The mode can be used with both kinds of data.

What is the definition of median in math?
the median is the middle number in a set of data.
What is the mode and median?
Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.
