Relationships Flashcards
When a sampling procedure is biased, increasing the sample will cause bias to
stay the same on average
Bias will cause sampling error to
stay the same on average
When the null hypothesis is false, increasing the sample size will cause the P-value to
decrease on average
When the null hypothesis is true, increasing the sample size will cause the P-value to
stay the same on average
Decreasing alpha will cause the Type I error rate to
decrease on average
Decreasing alpha will cause the Type II error rate to
increase on average
Increasing power will cause the Type I error rate to
stay the same on average
Increasing power will cause the Type II error rate to
decrease on average
Increasing the confidence of a confidence interval (ex. from 90% to 95%) will cause the width of the interval to
increase on average
Decreasing the sample size will cause the width of a confidence interval to
increase on average
