In statistical hypothesis testing,the relationship oftwo types of errorsand how to reduce the probability of them are discussed,and how to choose the appropriate testing method of one-sided statistical test is
The article compares five methods for testing the hypothesis of independence between two sets of variates. Two of the methods are new and based on straightforward generalizations of two robust measures of covariance recently appearing in the literature. Simulation results indicate that both of the new...
Review of Type I and Type II ErrorsInference is based on probability, so there is always some chance of making a wrong decision. Recall that two types of wrong decisions can be made in hypothesis testing. When we reject a null hypothesis that is true, we commi...

One of the first steps is to look up a z-score, and in order to do that, you need to know if it’s a one tailed test or two. You can figure this out in just a couple of steps. Back to top One tailed test or two in Hypothesis Testing: Steps One tailed test. Although this...
“In a two sided test comparing the area under the ROC curve (AUC) of a reference test to a proposed test for continuous response data using a z-test approximation, a sample size of 120 from the positive group (with the condition) and a sample size of 70 from the negative group (with...
Example of Two Sample T Test and Confidence Interval Null Hypothesis and Alternative Hypothesis What Is the Difference Between Alpha and P-Values? The Difference Between Type I and Type II Errors in Hypothesis Testing What 'Fail to Reject' Means in a Hypothesis Test An Example of Chi-Squ...
In this case, the parameter is the mean age of Nobel Prize winners when they received the prize (μ).The null and alternative hypothesis are then:Null hypothesis: The average age was 60. Alternative hypothesis: The average age is not 60....
Hypothesis testing to identify a difference between two proportions can be done by following several steps. See these steps outlined in an example of stating the hypothesis, finding and calculating critical and test values, and summarizing the results. ...
Hypothesis testing is a common method of drawing inferences about a population based on statistical evidence from a sample. As an example, suppose someone says that at a certain time in the state of Massachusetts, the average price of a gallon of regular unleaded gas was $1.15. How could you...
