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. ...

(If you must, seeHow to Calculate the Coefficient of Determination). There are many statistical packages that can calculated adjusted r squared for you. Adjusted r squared is given as part of Excel regression output. See:Excel regression analysis output explained. Meaning of Adjusted R2 Both R2a...
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...
What a Chi-Square (χ2) Statistic Can Tell You There are two main kinds of chi-square tests that will provide different information: The test of independence, which asks a question of relationship, such as, “Is there a relationship between student gender and course choice?” ...
The basic unit of area in the metric system is the square meter, which is a square that has 1 meter on each side:1 square meterBe careful to say "square meters" not "meters squared":There are also "square mm", "square cm" etc, learn more at Metric Area....
Hence tan A = 2 (.5 W / √(H2 + D2)), or simply tan A = 1 / √(H2 + D2), where “H” is the height of the observer. Because height is a constant, the denominator is changed by the square root of D squared, so we can further simplify the expression ...
