Sample Question 1
A p-value represents the probability of observing test results as extreme as, or more extreme than, the actual data if which condition is true?

The null hypothesis is true

The alternative hypothesis is true

The sample size is large enough

The population is normally distributed

Sample Question 2
If a researcher sets α = 0.05 and obtains a p-value of 0.03, what conclusion should be drawn?

Fail to reject the null hypothesis

Reject the null hypothesis

Accept the alternative hypothesis as proven

Increase the sample size and retest

p-Value Interpretation in Regression Output

This quiz evaluates your grasp of p-values in regression analysis. You'll learn p-value interpretation in regression output, differentiate between statistical significance and practical significance, and apply appropriate...

Sample Question 1
In regression output, what does a p-value represent?

The probability the null hypothesis is true

The probability of observing a test statistic as extreme or more extreme, given the null hypothesis is true

The probability the regression coefficient is nonzero

The proportion of variance explained by the model

Sample Question 2
If a regression coefficient has a p-value of 0.03 and α = 0.05, what conclusion is appropriate?

Reject the null hypothesis; the coefficient is statistically significant

Fail to reject the null hypothesis; the coefficient is not significant

The coefficient explains 3% of the variance

Accept the alternative hypothesis with 97% confidence
