Research Methods and Statistics: A Critical Thinking Approach
Remember, however, that when we reject the null hypothesis, we could be
correct in our decision, or we could be making a Type I error. Maybe the null
hypothesis is true, and this is one of those 5 or less times out of 100 when the
observed ...

Experimental Design and Data Analysis for Biologists
The different approaches for dealing with the increased probability of a Type I
error in multiple testing situations are based on how the Type I error rate for each
test (the comparison-wise Type I error rate) is reduced to keep the family-wise ...

Introduction to Research in Education
The consequences of a Type I error are generally considered more serious than

Statistical Methods for Health Care Research
The incorrect response would be to reject a true null hypothesis (type I error). If
H0 is false and we reject it, we have responded correctly. The wrong response
would be to accept a false null hypothesis (type II error). Suppose you compared
...

Statistics for Evidence-Based Practice and Evaluation
When a finding is statistically significant, the p-value is the probability that the
statistical conclusion (rejecting the null hypothesis and thus risking a Type I error)
is invalid. When a finding is not statistically significant, the probability that the ...

Research Methods: A Modular Approach
we have observed a significant difference in IQ scores between the sample and
the population. However, when we reject the null hypothesis, we could be correct
in our decision or we could be making a Type I error. Maybe the null hypothesis ...

Sample Size Calculations in Clinical Research
Precision analysis and power analysis for sample size determination are usually
performed by controlling type I error (or confidence level) and type II error (or
power), respectively. In what follows, we will first introduce the concepts of type I
and ...

Research Methodology: Methods and Techniques
The former is known as Type I error and the latter as Type II error. In other words,
Type I error means rejection of hypothesis which should have been accepted and
Type II error means accepting the hypothesis which should have been rejected ...

Introductory Econometrics: A Modern Approach
In hypothesis testing, we can make two kinds of mistakes. First, we can reject the
null hypothesis when it is in fact true. This is called a Type I error. In the election
example, a Type I error occurs if we reject H0 when the true proportion of people
...
