A normal distribution is a distribution that is bell-shaped and symmetrical. The mean, median, and mode are measures of central tendency. In a normal distribution, all are the same value.

Variance and standard deviation are two measures of variability. Standard deviation is the square root of the variance; therefore, variance is standard deviation squared.

I hope this helps.
