Exam 10: Statistical Significance

If a statistical program's probability output doesn't say differently,it is almost always a 2-tailed probability.

A probability level is just another name for the likelihood of random error.

Random error distributions can be used to estimate the amount of error likely to occur in a sample.

While it is common to use p = .05 as the criteria for significance,you don't absolutely have to.

If an inferential statistic's calculated value is statistically significant,that means:

An .05 level of significance means that

It is a more conservative decision to

When you have a one-tailed relationship,what would you normally do with the associated probability level?

If you don't have the probability associated with an inferential statistic's value and degrees of freedom

If a zero association exists,which of the following hypotheses would be supported?

Statistical significance does not mean that something is important.

If your probability level is lower than your alpha level,you should

Under which condition below would you reject a null hypothesis?

Statistical significance means

Which of the following is NOT true?

An inferential statistic cannot be interpreted unless you have:

A Chi-square test with an associated probability level cannot be interpreted unless you have the actual Chi-square value.

If an inferential test result is significant,you no longer have to worry about the direction of a hypothesis.

An alpha level is the name for dividing probability by two.

A probability level of .05001 with alpha level of .05 is
