A perfect square, also called a square number, is a number written by using the formula Sn = n2, where n is an integer. Image credits: mathsisfun.com Notice that: 0 squared is 0 (just make n = 0 in the formula Sn = n2) 1 squared is 1 (just make n = 1) Negative 0 squared...
A number expressed as a product of an integer by itself is called a perfect square. Since the same number is multiplied twice, the perfect square is also written as the second exponent of an integer. Thus, the squares of all integers are known as perfect squares.Example: 16 is a perfect...
R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...
Definition:R squared, also called coefficient of determination, is a statistical calculation that measures the degree of interrelation and dependence between two variables. In other words, it is a formula that determines how much a variable’s behavior can explain the behavior of another variable. ...
