Are the mean median and the mode the same in a unimodal symmetrical distribution?

No they are not the same in a unimodal symmetrical distribution and they will never be


What is the relation between mean mode median in symmetric normal distribution?

They are all the same.


How does the median affect the graph of a normal distribution?

A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.


In an uniform distribution is the mean and median the same?

Yes, they are. A uniform distribution is one in which the probability of each outcome is the same and, as a result, the mean and median are the same. A uniform distribution should not be confused with a set of random variables, all with the same distributions - much less the same values!For example, the median of a Poisson distribution is not the same as its mean. So if you have a number of random variables (RVs), each with the same Poisson distribution, their mean and median will be different. This is true of any set of RVs whose distributions are asymmetric.And it is very easy to see that the mode need not be the same. The outcome of a single roll of a regular die is the uniform distribution over the numbers {1, 2, 3, 4, 5, 6}. The mean and median are 3.5 but the mode cannot be 3.5 since that is not a value that can ever be observed.


In a perfectly symmetrical unimodal distribution is the mode and the median the same as the mean?

No, it is in general not true - for example for uniform distribution on [0,1] every number in the interval is a mode, but the mean is 1/2. The correct answer would be that a symmetric unimodal distribution has one mode equal to the mean (but may have modes elsewhere).

How are the mode and median the same?

Mean, median, and mode are all equal in a normal distribution.


Are the mean mode median are same in normal distribution?

Yes.


Are the mean median and the mode the same in a unimodal symmetrical distribution?

No they are not the same in a unimodal symmetrical distribution and they will never be


In a normal distribution you will always know that?

The mean is the same as the mode and median.


What is the relation between mean median and mode?

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.


In a normally distributed data set which is greater mean median or mode?

In a normal distribution the mean, median and mode are all the same value.


Does mode equals the median normal distribution?

Yes it is. The normal distribution is symmetrical around the mode. Therefore the median has to be the same :)


How does the median affect the graph of a normal distribution?

Do the mean median and mode of a collection of numbers always have to be different?

No, in a normal distribution they are the same.


What is the relation between mean mode median in symmetric normal distribution?

They are all the same.


What is the relationship among the mean median and mode in a symmetric distribution?

They are all equal . . . they are the same.(In an asymmetric distribution they are not equal.)


Is normal distribution bimodel?

No.  Normal distribution is uni-modal, specifically with the mean, mode, and median at the same value.
