Accordingly, are all bell shaped curves normal distributions?
All normal distributions are symmetric and have bell-shaped density curves with a single peak. To speak specifically of any normal distribution, two quantities have to be specified: the mean , where the peak of the density occurs, and the standard deviation , which indicates the spread or girth of the bell curve.
Secondly, what does a normal distribution curve show? normal distribution curve. In statistics, the theoretical curve that shows how often an experiment will produce a particular result. The curve is symmetrical and bell shaped, showing that trials will usually give a result near the average, but will occasionally deviate by large amounts.
Also to know is, what does a bell shaped curve mean?
bell curve. A symmetrical bell-shaped curve that represents the distribution of values, frequencies, or probabilities of a set of data. It slopes downward from a point in the middle corresponding to the mean value, or the maximum probability.
Is Bell Curve still relevant?
The Bell Curve system of performance appraisal intimidates HR managers as much as employees. For a long time, this forced ranking system has remained a topic of debate, but companies still continue to use it.
