WebKey Points. The Inverted-U Theory illustrates the relationship between pressure and performance. Also known as the Yerkes-Dodson Law, it explains how to find the optimum level of positive pressure at which people perform at their best. Too much or too little pressure can lead to decreased performance. WebCircles, Ellipses, Parabolas and Hyperbolas. Our page on Polygons covers shapes made with straight lines, also known as ‘plane shapes’. This page explains more about shapes with curves, especially two-dimensional ones. Two-dimensional curved shapes include circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments.

This theorem states that the mean of any set of variants with any distribution having a finite mean and variance tends to occur in a normal distribution. WebADVERTISEMENTS: This article throws light upon the fifteen main principles of normal probability curve. Some of the properties are: 1. The normal curve is symmetrical 2. The normal curve is unimodal 3. Mean, median and mode coincide 4. The maximum ordinate occurs at the centre 5. The normal curve is asymptotic to the X-axis 6.
