Webb1 aug. 2007 · The spread (width) of the curve around the mean is determined by its sd. The shape of any normal distribution frequency curve is entirely described by these two parameters. The centre of the distribution occurs at the zenith and all three measures of central tendency (mode, median, and mean) are equal and described by the zenith.

WebbDoes the histogram have a single, central hump or several separated bumps? o Humps in a histogram are called modes. o A histogram with one main peak is dubbed unimodal; histograms with two peaks are bimodal; histograms with three or more peaks are called multimodal. o A bimodal histogram has two apparent peaks: http://cisdmath7.weebly.com/blog/center-spread-and-shape-descriptions
