The area of a two-dimensional shape is defined as the amount of space covered by the shape if we were to keep it on a flat table.For a square of side length “s” units, the area is given by the formula:Area =side×side=S2The area is expressed in square units, such as cm2, c...

Learn what a square meter (or meter squared) -- the SI unit of area -- is and how it's measured. See how to convert it to other units.
A chi-square (χ2)statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample. For example, the results of...
The most common application of this method is sometimes referred to as linear or ordinary. It aims to create a straight line that minimizes thesum of squaresof the errors generated by the results of the associated equations, such as the squared residuals resulting from differences in the observed...
