## How do you fix a Type 1 error?

Bill K. The probability of a type 1 error (rejecting a true null hypothesis) can be minimized by picking a smaller level of significance α before doing a test (requiring a smaller p -value for rejecting H0 ).

## How does sample size affect error?

The relationship between margin of error and sample size is simple: As the sample size increases, the margin of error decreases. Looking at these different results, you can see that larger sample sizes decrease the margin of error, but after a certain point, you have a diminished return.

## Does power affect type 1 error?

Graphical depiction of the relation between Type I and Type II errors, and the power of the test. Type I and Type II errors are inversely related: As one increases, the other decreases. A related concept is power—the probability that a test will reject the null hypothesis when it is, in fact, false.
