 The var() function computes the variance of a variable.

Example:

# Calculate the variance of Thumb

var(Fingers$Thumb)

# Alt: use 'data =' argument instead of '$' (produces same output)

var(~Thumb, data = Fingers)

Example output:

  Variance is also called MS, Mean Square; approximated by the sum of squares (SS) divided by the degrees of freedom (i.e., n-1); the MSE from the empty model can be thought of as roughly the average squared deviation.

• confounding variable

  Confounding variable is a variable that, though not measured, causes variation in both the explanatory variable and the outcome variable; also know as a "lurking variable" or a "third variable".
