WebA normal distribution is continuous. A normal distribution is symmetric about its mean. The mean, median, and mode are equal for a normal distribution. The variance of normally distributed data is equally distributed about the mean. The graph forms a bell-shaped curve such that the maximum value is the mean.

In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation. The variance of the dis…
WebAn extremely common example of a symmetrical distribution is the normal distribution (bell-shaped curve). So the mean and median of a normal distribution are the same. Since a normal distribution is also symmetric about its highest peak, the mode (as well as the mean and median) are all equal in a normal distribution.

If we changed the 4 and 5 to 400 and 500, the median would still be 3. So for the median, it's not so much the size of the outlier, but rather how many there are. For the mean, even a single outlier can have a big effect if it is extreme enough. flytogether appWeb23 de set. de 2016 · I have the minimum, mean, and maximum of some data set, say, 10, 20, and 25.
