## How are CV scores calculated?

The formula for the coefficient of variation is: Coefficient of Variation = (Standard Deviation / Mean) * 100. ) * 100. Multiplying the coefficient by 100 is an optional step to get a percentage, as opposed to a decimal.

## How do you know if a model is Overfitting?

Overfitting can be identified by checking validation metrics such as accuracy and loss. The validation metrics usually increase until a point where they stagnate or start declining when the model is affected by overfitting.

## How do you mitigate a Type 2 error?

How to Avoid the Type II Error?Increase the sample size. One of the simplest methods to increase the power of the test is to increase the sample size used in a test. Increase the significance level. Another method is to choose a higher level of significance.

## Why is Type 1 and Type 2 error important?

Specifically, they can make either Type I or Type II errors. As you analyze your own data and test hypotheses, understanding the difference between Type I and Type II errors is extremely important, because there’s a risk of making each type of error in every analysis, and the amount of risk is in your control.
