Is unimodal a normal distribution?

It may be or may not be; however a normal distribution is unimodal.


Does the standard normal distribution is unimodal?

Yes it is.


Normal distribution is symmetric with single peak.Does this mean that all distibutions are normal?

No, not all distributions are symmetrical, and not all distributions have a single peak.


Are all symmetric distributions normal distributions?

No. There are many other distributions, including discrete ones, that are symmetrical.


Does a normal probability distribution include a bimodal distribution?

No, the normal distribution is strictly unimodal.


What is unimodel?

Unimodal is having a normal disturbution. The mean, median, and mode are all a the center. When looking at a graph, there is one maximum.


Does all symmetrical distributions are normal distribution?

It is not necessary that all symetric distribution may be normal.


How would you describe the shape of a normal curve?

Bell-shaped, unimodal, symmetric


Does this means that all symmetric distribution are normal Explain?

Don't know what "this" is, but all symmetric distributions are not normal. There are many distributions, discrete and continuous that are not normal. The uniform or binomial distributions are examples of discrete symmetric distibutions that are not normal. The uniform and the beta distribution with equal parameters are examples of a continuous distribution that is not normal. The uniform distribution can be discrete or continuous.


Why is the mean and median not pratical when it comes to the mode?

The three are different measures of central tendency. None of them are substitutes for the other and, except in symmetric unimodal distributions, none of them can be used to estimate another.


Do t distributions have less spread than normal distributions?

I think yes or no


Can the standard normal variate in normal distributions be negative?

About half the time.
