“In most real world problems multiple alternative hypotheses compete to explain the data. However, by using NHST we can only reject H0 and argue for some H1 without any formal justification of why we prefer a particular hypothesis whereas it can be argued that it only makes sense...
A Type I error represents the scenario which occurs when a researcher chooses to make the decision to reject a null hypothesis, when in fact, the null hypothesis is correct and it should have been retained. The Type I error is associated with the alpha level of the stud...

In the hypothesis testing, we have two types of error: type I error and type II error. The type II error is also known as the consumer risk,β. The type I error is also known as the producer risk.α. Statistical Terms: The null hypothesis is a statement found at the ...
Based on the results, the assumed null hypothesis is accepted or rejected. If the null hypothesis is rejected, it indicates that data readings are strong and are probably not due to chance. Null hypothesis rejected: Differences are statistically significant Null hypothesis...
Which testing is used for directional hypothesis? If the sample being tested falls into the one-sided critical area, the alternative hypothesis will be accepted instead of the null hypothesis.A one-tailed testis also known as a directional hypothesis or directional test. ...
may increase the probability of Type II error, since the difference between locally explosive term and local unit root term will have an impact on the KSS test statistic, which may suggest that the coefficient on the cube of yt−1 is not significant and the null hypothesis is accepted. In...
is male) because it is definitely riskier than a false positive (detecting a male when it is female). Furthermore, as the applied psychometry has demonstrated (Chadha,2009), the false negative error (i.e., type I error rejecting the null hypothesis [H0] when it is true: detecting a ...
Answer to: If the null hypothesis is rejected when it is true, a ___ error has occurred. a) Power b) Type I c) Type II d) Type III e) None of...
If you reject the null hypothesis and it is false, what type of error is this? When the null hypothesis is not rejected, there is no possibility of making a type I error. What is failing to reject the null hypothesis when it is false called?
