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 does the peak of a bell curve represent?
The peak of a bell curve, also known as the normal distribution, represents the mean, median, and mode of the data set, where the majority of data points cluster around this central value. It indicates the highest frequency of occurrences for a particular value, highlighting that most observations fall close to the average. As you move away from the peak, the frequency of values decreases symmetrically in both directions, illustrating the variability within the data.
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
The second quartile of a data set is also called the?
median or middle
Is there ever more than one median?
No, there is never more than one median in a data set. The median is defined as the middle value when the data is arranged in order. If the data set has an odd number of observations, the median is the single middle value. If it has an even number of observations, the median is the average of the two middle values, which also results in a single value.
Does median require the data set to be in order?
Yes, to calculate the median, the data set must be arranged in order, either ascending or descending. The median is the middle value of a data set, and without sorting, it is not possible to accurately identify this central point. For an even number of values, the median is the average of the two middle numbers, which also requires the data to be ordered.
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.
What divides a set of data in half?
Median
Which is the middle number in a set of data?
Median .
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.
