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.
this was exactly what i needed. thank you!
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.
bruh.......where was this when i was in stats. I'm mad
WHERE ARE YOUU
actually saving my ass
Years later… this video helped me so much. I love you
can i do it without table using calculator?
Thank you sir for brilliant explanation 👏
You are great man ! God bless you
more then a decade later and here i am watching this days before my exam
Thank you so much. I was confused about two concepts: test statistic, and critical value. Now I understood. Thanks!!!!
I dont get how alpha .10 is -1.28 when I got the .05 =1.645
Ugh wish I found this before the end of semester :(
YOURE A LEGEND MATE
this makes me understood the lesson well, thank u for this
I love and understand math way better when I see it written out. Stay original and authentic with these paper videos. Thankyou!
still helped me 11 years later, thank you
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.
should the terms always end up on the left side of the equation?
For the 3rd example, why are we not subtracting -0.21 from 1 as Z>-0.21? I have this doubt, could you please help.
wa ko kasabot
Thank you! Super helpful!🙏🏼
Really helpful and clear explanations! ❤
thank you so much
thank you bro
Tomorrow have exams thank you
Thank you💕
Superb 🙏🙏
Excellent
Thanks a ton. Excellent presentation.

Hello, my fellow Boston Celtics fan. Ray Allen was a true 3point legend of the game.
i love you more than life itself
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?
At the lowest point in my life right now. I've never wanted to go off the grid and live in a cave more than I do right now.
You might’ve commented on the wrong video
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 😂😘❤
exactly how i feel right now man
I’ve never understood why we reject the null when the P-value is less than alpha. If someone knows plz share, Ty
thank you very much good sir
Thanks cus my stats instructor couldn’t nearly explain it as clearly as this.
Thank you sir you saved my life
how u find negative cut of score -2.01 ....tell me clearly
not helpful at all.
The percentile explanation was fantastic. What's the significance of Z. Why is it important for us to know a z value
can we do this using a calculator?
My goat
Thank youuuuu
Thank you. I somehow forgot how to find the slope and this video helped.
Wow Sir excellent❤❤
