What else can I help you with?
Can you accept a null hypothesis under the t statistic and then reject the same null hypothesis using the F statistic?
At the same level of significance and against the same alternative hypothesis, the two tests are equivalent.
How is null hypothesis tested?
The null hypothesis is typically tested using statistical tests such as t-tests, ANOVA, or chi-square tests. These tests calculate the probability of obtaining the observed data if the null hypothesis were true. If this probability (p-value) is below a certain threshold (usually 0.05), the null hypothesis is rejected.
What do you do when your conclusion don't match your hypothesis?
T
How do you decide whether to use a z test or a t test when testing a hypothesis about a population mean?
You use a z test when you are testing a hypothesis that is using proportions You use a t test when you are testing a hypothesis that is using means
Is Paired samples T-test an example of nonparametric tests?
A paired samples t-test is an example of parametric (not nonparametric) tests.
On average what value is expected for the t statistic when the null hypothesis is true?
When the null hypothesis is true, the expected value for the t statistic is 0. This is because the t statistic is calculated as the difference between the sample mean and the hypothesized population mean, divided by the standard error, and when the null hypothesis is true, these values should be equal, resulting in a t statistic of 0.
What is the meaning of hypothesis in statistics?
A hypothesis is the first step in running a statistical test (t-test, chi-square test, etc.) A NULL HYPOTHESIS is the probability that what you are testing does NOT occur. An ALTERNATIVE HYPOTHESIS is the probability that what you are testing DOES occur.
How do Hopi Indians and turtles relate?
It doesn"t you fool
Does a directional hypothesis force the t Test to be directional as well or vice versa?
Yes. The hypothesis comes first. That determines the nature of the test.
What has the author T Balkir written?
T. Balkir has written: 'Triaxial tests on soils'
How did the scientific Revolution contribute to the revolution?
i t provided a way to test a hypothesis.
When the null hypothesis is true then the t statistics will have an average value of?
There can be no proper answer since it is not known whether the alternative hypothesis is one sides or two sided.
