Calculates the exponent to which 10 must be raised to equal a given number. For example, 10^{2} = 100, so the log base 10 of 100 is 2. Log base 10 is defined only for positive numbers. When you multiply a number by 10, you increase its log by 1; when you divide a number by 10, you decrease its log by 1.

Syntax

LOGTEN(number)

In number, specify the value or column of values. Minitab computes the value x such that 10^{x} = the number. If you enter 0 or a negative number, Minitab stores a missing value *.

To make positively skewed data more "normal"

To account for curvature in a linear model

To stabilize variation within groups
