Welcome to POYSERMATH on KZread! This channel was created specifically for Prof. Poyser's math students at Quinsigamond Community College (QCC) and Worcester State University (WSU). These videos answer the most frequently asked questions by my students in class.

I have made my videos "public" so that any math student around the world can view them. Please forgive me if I do not respond to specific questions that you may ask on this channel. I do not check this channel every day.

Who knows, perhaps one day, my own two kids (who've made fun of my "boring" videos when I record them at home) will watch these videos and help them too! LOL

I sincerely hope they help you.
-Prof. Poyser

    What about when a probability isn't an even .20, .30., etc.

    BY far the best explanation of SHADING area when given the AREA to find Z-value. TIP: for other people i find it it EASIER for to me UNDERSTAND it like this LESS THAN means shade from LEFT side (corner) to the right side

    This was recorded 10 years ago but it's still relevant and very helpful. I spent 4 days trying to understand the basics of hypothesis testing, but I failed to find videos. Most videos are so advanced. Thank you so much for this simple yet effective insight into the rules and approach of the hypothesis.

    You know, for a video made over a decade ago, I appreciate how willing you are to find an easier route. Today's textbooks make this process more complicated than it needs to be and I've always thought the math was a little bit too much work. Sincerely, thank you.

    So being in the 96 percentile means that i scored above all those ppl, and it means that im within 4 percent of the populaton. So the probability of getting such a score thag puts you above 96% is 4%?.

    What if the z-critical is equal to z-test value? Do we reject or not reject H0?

    I get it, you commented on the right video. I was very suicidal growing up, I over came, but life is not easy. I pray you know the fullness of how much you are loved, even when you don’t see it or feel it. You have you and you were created for love, life and purpose. I pray this darkness be removed from your life and that you see a new light dawning, love wants something to do with you, take hold of the hope of knowing that if you are still here, still breathing, still walking, talking, your heart is still beating then you are still needed. Don’t let this lowest point take you from your superpower ability to climb from the ashes, because we humans are resilient, strong and overcomers . God speed to your situation and peace like a river. You got this. Now I have to get back to this dang math, cause I have no idea what I’m doing 😂😘❤
