R squared also called the coefficient of determination is the portion (%) of the total variation of the dependent variable that is explained by the variation in the independent variable. This is found by dividing the sum of squared regression (SSR) by the total sum of square errors (SST) that is R^2 = SSR / SST.
- When there is a perfect linear relationship between the variation of the dependent variable y and the variation of the independent variable x R^2 is equal to 1.
- The R^2 for any weaker linear relationships will range between 0 and 1 exclusive.
- Finally when there is no relationship between the variations of the y as a result of the variation in x R^2 is equal to 0.

How do you convert the volume of a cylinder from squared to cubed?
Volume of any 3-dimensional object is always 'Cubic'. 'Squared' refers to area. The volume of a cylinder is V = pir^2h Where pi r^2 refers to the area of the circular profile of the cylinder., which is a 'squared' value/ 'h' is the height of the cylinder , which is a linear value. When a squared value is multiplied to a linear value , it becomes a cubic value.

What does r squared mean in a regression analysis?
R-squared, or the coefficient of determination, measures the proportion of variance in the dependent variable that can be explained by the independent variable(s) in a regression model. It ranges from 0 to 1, where 0 indicates that the model explains none of the variability and 1 indicates that it explains all the variability. A higher R-squared value suggests a better fit of the model to the data, but it does not imply causation. Additionally, R-squared should be interpreted in context, as a high value may not always indicate a meaningful or useful model.

How do you find the r value of a r square value?
To find the Pearson correlation coefficient (r) from the R-squared (R²) value, you simply take the square root of R². If R² is positive, r is the positive square root of R²; if R² is negative (which is not possible since R² ranges from 0 to 1), r would be negative. Thus, the formula is r = ±√R², where the sign depends on the direction of the relationship (positive or negative correlation).
What does radius squared look like?
Radius squared, often denoted as ( r^2 ), represents the area of a circle when ( r ) is the length of the radius. Mathematically, it is calculated by multiplying the radius by itself (i.e., ( r \times r )). In terms of a formula for the area of a circle, it is used in the equation ( A = \pi r^2 ), where ( A ) is the area. Thus, radius squared is simply a numerical value reflecting the size of the circle based on its radius.
