AP Statistics Full Unit 7 Summary Video - Inference for Means

Inference is all about using statistics from a sample to make judgments about a parameter from a population. In Unit 7 of AP Statistics inference for Quantitative Data is covered with a focus on means. This video reviews all of the key aspects from this unit with some examples to go along with it.

Hi Mr. Porinchak, I really wanted to thank you for saving my life😭
I was on the verge of giving up on AP Statistics due to the lack of teaching at our school, but I have hope because of your videos! Thank you SO much and I really appreciate your hard work. I know it's not easy to film a video for an hour straight, but you did a great job on it. Thank you♥

hi so if our sample isn't big enough (n<30), and we check the histogram it forms and it turns out to be bimodal or like completely uniform, basically not normalish at all, do we still go forward with using it? as long as we don't see major skewness or outliers?

THANK YOU SO MUCH!!!! Your videos have helped me so much! I love the examples and how you summarize each unit!

Hello agian! I have a quick question! Some of our practice FRQs we have in school has outliers. What do I do? Do I make a new distribution and omit the outliers?

Hey Mr. Porinchak for step 2 in these problems do we have to draw the sampling distribution or can we just write the mean difference and the standard error of difference?

How do we know when to use t-value and z-value? How do we differentiate between that?

[CodeWinston]

Hello! Just a quick note, in your first two sample mean confidence interval, I think you forgot to state your hypothesis!
