What does it mean when data is normally distributed

A special notation is employed to indicate that X is normally distributed with these parameters, namely X sim Nmu, sigma. In statistics and research, you will often hear the term normal distribution, but what exactly does this mean. This is a probability density function, of the exponential family, defined by the two parameters, its mean and variance. What does it mean for a population to be normally distributed.
Property of probability distributions is that area under curve equals one. What does this really mean, though. Doing so means that you need to consider the distribution of your data. It is a general concept that applies to data that arise from any distribution. You can see a normal distribution being created by random chance.

One finds the area under any portion of the curve by integrating the distribution between the specified limits. Gender determining chronosomes, X, Y are not autosomes. In fact, in any symmetrical distribution the mean, median and mode are equal. Can normal distribution be used if the data is not normal. For normally distributed vectors, see Multivariate normal distribution.
