STAT 201 Discussion 15 comic
Storyboard Text
- Hey James! In Statistics this morning I was kind of confused on how we use different methods to either reject of FTR the Null.
- Hey, no worries Megan! I can help you understand how to use the p-value, T-statistic, and Confidence Interval to form a decision about the Null!
- So, basically when looking at the p-value, if the p-value is less then 0.05, you reject, but if it is greater than 0.05, then you FTR the Null!
- Ahhhh okay, okay, I am starting to pick it up!
- When it comes to the T-statistic, if the absolute value of the T-statistic is greater than 2, you reject, but if it is less than 2, you FTR the Null!
- Lastly, you can reject the Null is outside of the CI and if it is inside the CI you FTR!
- Now, let's check your understanding. What would your decision be if the p-value was 0.01 and the absolute value of the T-statistic was 7.33?
- Hmmmm let me think.... is it Reject the Null?
- YES!!! You got it! Great Job Megan!!
- Oh my gosh!! I finally get it!! Thank you so much James, now I feel confident in making that statistical decision!
