Why is 2-tail p-value twice the 1-tail p-value?
Add Your Heading Text Here Why is the two-tail p-value always twice the one-tail p-value in a t-test? In the t-test output below, notice that the two-tail p-value is 0.66852 while the one-tail p-value is 0.33426. The two-tail p-value is twice the one-tail p-value. Why is this true? The two-tail p-value is defined as P …
Correlation: Introduction to Relationships
In the last lesson, you learned about the Two-way Chi-square Test for Independence. Using it, you can determine if two categorical variables are independent. If two variables are not independent, they are related. Knowing something about one variable can tell you something about the other variable. In this lesson, you will explore further this idea …
