StatPiFinally see why every step is there.
You have the numbers and the formula, and no idea why this test and not the one next to it. Bring that question to two free hours with Professor Paul Weiss, PhD. He works it live in StatPi: which test, why that one, and what the answer means. You leave able to explain the step, not just copy it.
Starts Sunday, November 8 at 7 PM Eastern.
Is 83 a good score? Depends on the room. Paul shows you how to say exactly where you stand.
Three things you can use on Monday.
Your problem, worked to the end
Which test, why that one and not the one next to it, the numbers that go in, and the answer that comes out.
t = 2.4 / 1.2 = 2.000, df 24
A way to check your own work
The steps on screen are the same ones StatPi writes out for you, with the same answers R gives. Next time you can check yourself before you hand it in.
R p = 0.0285
The sentence for the exam
What the output means, in one sentence you could write under your answer, so the number stops being a number and starts being a conclusion.

Professor Paul Weiss, PhD
Dr. Weiss began his career in statistics in 1993. His work includes collaborations with the Centers for Disease Control and Prevention, the American Cancer Society, the United States Navy, and health ministries in India, Hong Kong, Japan and the Republic of Georgia.
On the faculty of Emory University's Rollins School of Public Health in Atlanta, he taught introductory courses in statistical methods as well as advanced electives in statistical programming and survey methods.
He has been described as an early adopter of teaching technology. At Emory he engineered a mobile workstation so he could move freely around the computer lab and stay connected to the teaching station at the front of the room, and he combined smartboard technology with static presentation systems to give his students more ways to learn. StatPi is the next step in that habit: an app that teaches statistics, not how to be a statistician.
Your host for the room: Adam LaBare, StatPi's founder. He opens the session at 7 and drives StatPi on screen while Paul teaches.
Two hours, Sunday night, Eastern time.
- Room opensAdam LaBare opens the room and says how the night works. Type your class and the topic you are stuck on in the chat. Questions are welcome the whole night.
- A problem Paul has not seenWorked cold, out loud: which test, why, the assumptions, the output, and what it means. You see how a statistician thinks, not just what he types.
- The problems you sent aheadIn the order they came in, about 8 to 10 minutes each, step by step in StatPi. Chat questions get answered as they come.
- For the people who teach itA short look at running a class session in StatPi, for anyone who teaches statistics.
- Last questionsAnything still open. Then the date of the next session.
Times are a guide. When a problem needs longer, it gets longer.
That is when the week is staring at you.
Exams, homework, the problem set due Tuesday. Come Sunday, use it Monday.
If you are taking statistics
Send the problem you are stuck on. Copy it exactly, numbers and all. You do not need StatPi to come.
If you teach it
Pick "I teach it" on the form. We will set up a walkthrough of StatPi for you and your course, including live class sessions.
Save your seat.
The link to the room comes by email before we start. Send the question you are stuck on and it may get worked first.

You are in for Sunday, November 8, 7 PM Eastern.
Watch your inbox for the confirmation. The room link follows before the night.
Before you come.
Does it cost anything?
No. Office Hours is free, and StatPi Lite is free.
Do I need the app?
No. Watch, ask in the chat, and try StatPi afterward if it helps.
Will my problem get worked?
Paul works as many as two hours allow, starting with what people send ahead on the form. Copy the problem exactly, numbers and all.
What if my class uses R, SPSS or a calculator?
Come anyway. The reasoning is the same in every tool, and StatPi gives the same answers R gives, so you can check one against the other.
Is this help with a test I am taking right now?
No. Homework, practice problems and studying, yes. An exam that is open right now, no.
Will there be a recording?
Come live if you can; that is when your question gets answered. Registered guests will hear what is available afterward.
I teach statistics. Is this for me?
Yes. Pick "I teach it" on the form and we will set up a walkthrough of StatPi for your course, including live class sessions where every phone in the room sends its numbers to your screen.
Keep the steps in your pocket.
The next problem set comes at midnight, when there is nobody to ask. StatPi is the app Paul works in on the night. Type the numbers from your problem and it writes out every step between the formula and the answer, with the same answers R gives, so you can check yourself before you hand it in.
