Question

what measures the extent to which the predictions change between various realizations of the model ? bias difference variance deviation

Answer 1

Variance is the answer

Answer 2

Variance: The measure of the deviation from the expected value is defined as variance.

Variance = Average of the squares of the differences between the individual and the expected value.

As the change of predictions between different models are calculated, variance is used to find the deviation in the predictions.

Hence, Variation measures the extent to which the predictions change between various realizations of the model

The answer is Variation.
