How to Insert a Square Root in Excel | Techwalla
1. Every positive real number has two square roots; one is positive and the other is negative. They are opposites of each other. 2. Negative real numbers have no real number square roots because any nonzero real number is positive when squared. 3. The square root of 0 is 0. If a 0 and b 0, then if and only if a2 = b; a. is called the

The square root transformation essentially gives higher weight to smaller values, those values with higher information content (lower variance). In general, we can say that data requiring the square root transformation do not violate the ANOVA assumptions nearly as drastically as data requiring a log transformation.
