Thx!

[@migel19051979]

Thanks for the visual explanation! Can you explain what is the advantage of a calculator over spreadsheets (for example, Excel)? Who needs calculating statistics on calculators?

[@lbstats]

In life, A spreadsheet would be far better than a calculator. A calculator is just more of a classroom format tool. As a professor we often don’t want our students on the computer while taking a test.

[@heavyduty152]

This is an awesome way for me to learn how to do stats. Most people say that's its hard. Of course it is especially when you don't know how to use the calculator. I also leaned how to use the Finance calculator on here. Thanks so much. I will be receiving my A in stats this semester. I am dedicated and motivated

[@lbstats]

tasha reives thanks for taking the time to comment. I’m glad this was helpful, and congratulations on getting an A in your class.

[@firerock360]

Thank soo much for your video this is going to help me on my final exam.

[@lbstats]

firerock360 glad it helped.

[@naomiguechussi1113]

So how do you get the mean?

[@lbstats]

Naomi Guechussi After you select“Calc”, the mean is listed as the first figure after the x-bar symbol. The calculations for a sample mean and the population mean are identical so even though x-bar is listed, the value is also the same as mu, the population mean. I hope that answers your question.

Help! I follow this step by step but sx is always coming up blank!! Please help me how do I fix this? I also have the TI-83 plus calculator

[@lbstats]

Hi, sorry this reply got buried. Did you resolve the issue? All I can think of Is that you ran some other list before going to the SX button.
