Yes. And in any symmetric distribution, they will.
(10, 15, 15, 15, 20) The answer above displays a sample in which the sample mean, sample median and sample mode assume the same value. If you were asking about populations, then the population mean, population median and population mode are the same whenever the probability density function for the population is symmetric. For example, the normal probability density function is symmetric, the t and uniform density functions are symmetric. Many are.
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
It is easy to get a median with an odd amount of numbers, as there will always be one number in the middle of the list. So, for example, if you have 7 numbers, n1, n2, n3, n4, n5, n6, n7, the 4th number is always the median, so n4 would be the median value in this case.
The median is the middle number when numbers are put in order. If there is an even amount of numbers, then it is the value half way between the two middle numbers. There are an even amount of numbers in this case. As both of them are 62, then the median is 62.
All equal.
If it is a symmetric distribution, the median must be 130.
They are all equal . . . they are the same.(In an asymmetric distribution they are not equal.)
No. The mean and median are not necessarily the same. They will be the same if the distribution is symmetric but the converse is not necessarily true. That is to say, a distribution does not have to be symmetric for the mean and median to be the same. For example, the mean and median of {1, 1, 5, 6, 12} are both 5 but the distribution is NOT symmetric.
In a symmetric distribution, the mean and the median are the same. Otherwise there is no relation. In symmetric distributions with only one mode, the mode will coincide with the mean and median, but otherwise there is no relation.
Mean
yes
Yes, they can.Yes, they can. In a symmetric distribution they will be the same.
Median.
Yes. And in any symmetric distribution, they will.
That would provide some evidence that the distribution is symmetric about the mean (or median).
