first I pass calculus, then a math course, then a physics course and now a statistics course thanks to this godlike human being.

Thank you so much for this. My professor isn't teaching anything like this. Honestly, he makes it harder to understand. The couple hundred dollar stats book I bought doesn't explain this. My professor didn't explain this in any of his materials (Powerpoints, notes, lectures). Luckily, the University of RUclips had me covered. My tuiton should be going to you, my friend. Thank you again.

[@crisbello3302]

your prof doesn't know pedagogy

so true, youtube university is such a blessing.

no one can teach me better than you do honestly. chemistry and maths have been easy because of you. thank you so much for making calculation life easy

you carried me through chemistry, and now you're carrying me through stats. a literal god.

The entire comment section is already revealing my mind.
You are an awesome tutor like no other, you broke down this mountain of confusion into an ant hill for me. Thanks a lot.

[@xnikk0l]

These videos have saved me on numerous accounts from completely bombing my online classes. Thank you so much for these straight forward videos. I seriously would not have survived virtual learning without them!!

[@adisaseyi1945]

I am having my statistics exam in 3 days and I can say it boldly that I have learnt more here in 7 mins than I did throughout the semester. Thank you❤️

I learnt the whole unit but want sure how to get z value. I just memorized them. Now I saved my life. Thank you so much.

[@jacobvelasquez2234]

Thank you a lot, I’ve been having troubles with Edmentum and there way of teaching is no way near as great as yours, which is why I’m here learning more about Z-scores and Confidence Levels 😭😭 thank youuu!!

[@siryramseyram]

I've been trying to get this since the beginning of the semester, it's half past the semester and l got my savior this dawn.
Thanks for you help and may God richly bless you mannn!!!!❤❤❤

[@jonathanlindberg1426]

ABSOLUTELY incredible. I had a similar exercise in my class, and this method is so much quicker than the pain-in-the-ass-method my professor provided. THANK YOu!!

[@lindawillis7441]

You've made the concept clear and simple to understand and apply with your explanation and visual. Appreciate you covering not only z score table lookup, but also how to calculate the area value. Thank you!

[@katieblythewrites]

THANK YOU!!! I could not figure this out, you did an excellent job of explaining this!!

[@moddedinkling4168]

Thank you so much for this! Within less than 5 minutes of this, I learned more about how to find the CL Z-Score than from a teacher who just blabbered his way through a stupid 45-minute lesson which simply involved him re-reading his work and didn't even show us this freaking formula! I am so glad to have found this video.

[@vedantkarale4077]

Is this got z-alpha ?

[@Dark_Peace]

I have exam in 4 days and in 1 min, I learned and understood more than in 4 months. What would collège students do without ytb ? Thank you !

Thank you so much Sir. I really can't thank you enough. Thank you for all you do for students like me. God bless you greatly.

Greatly helped me to understand z table , area on the left side is so effectively explained. most of the experts don't explain it.

I could forget the formula, but the way it was explained with the chart example, it cannot be forgotten!!

[@priyankal4993]

Thanks a lot. I had to use this concept in some portfolio mgt related study. I had totally forgotten the concept and did not have anything handy to revise the basics. Your video came as a rescue. Many many thanks.

Saved me from pulling my hair out. My instructor doesn't explain any of this or make it so simple to understand, so thank you!

Spent two years trying to pass stats. This is the first time anyone has ever made me gasp in realization that it could be this easy.

What a great Teacher😊💞

[@hocuspocus8433]

wow the king of stats...I was used to play guess game by calculating the sum of the percentages at the left of the theoretical Z :D!! THX

[@alphonsekay2852]

Thank you, you explained it better than my teacher

[@martian0x80]

For all those who don't have/get a table (like me) during your exam, you can use the Inverse Normal PD function with area: (1+CFL)/2, mean: 0, and sd: 1, this should give you the z-score.

[@nurrodenthyme1671]

Thank you, a thousand times. If you ever have the misfortune of taking statistics using Pearson online resources, you'll find a large number of problems where the instruction is "use technology to find [a variable]" with no explanation of what kind of "technology" to use or the name of the formula. Now I have the name of the calculation I can use. I spent about 3 hours trying every search in Google I could think of, but online searches only go so far without the right words...

[@alexfernandez2963]

This is so helpful! Thank you for explaining it in such an easy way

I have statistics exams next week Monday and I never knew it'd was this simple 😮

[@conorreilly9418]

Thank you so much, you are a hero to students everywhere

[@k0zyc4t]

do we always have to use the table when figuring out the z-score?

[@luzgonzalez7624]

Thank you so much!!!!! Im taking statistic online and I had no idea that we needed to use the chart to find the value!! Headache gone, and now I can do my homework.

much

how do we calculate area and z score for one tailed tests then?

[@linaguo3740]

Bro I'm streaming through all your videos, and no offence to my teachers but 10 minutes of your videos is worth at least a day of work.

Thank you for this, my professor teach me very fast and i didn't notice about this. Another student who clever understand soo fast and me i need many days to know about this.

doesn't the z value differ for different tail test, u are finding for 2 tail test right. How to do the same for one tail left and right

[@roxanner632]

Thank you random internet person. I had a mental breakdown in a coffee shop yesterday trying to figure this out because my textbook did not explain how to find this value and I felt like I was losing my mind. God I love the internet you are my savior please pat yourself on the back

Why is only the area under the curve to the left is calculated, do we have area under the curve to the right ? Or finding area as two tail?

How the values came in the table of Z score? What's the logic behind the table? Can we find 2-tailed z-score using this table?

[@TECHASPIRANT]

Sir you have always saved us !!

[@trentrodgers1875]

I have come to you for Chemistry, Physics, Electrical classes, and now statistics… future engineers reading this (probably) ancient message work hard and learn from your resources like Jeff Hanson (statics, dynamics) and Organic Chemistry Tutor ( literally everything)

[@The_Wailing_Doom]

I am a little confused still. An 86% confidence level has an 1.48 Z-score. In the Z-table, the Z-score corresponds to .9306, not .93. Are we supposed to just get as close as possible?

[@antonioromero878]

Yes. You will have a small "standard error" if you will

you are good man you know!

[@ziomy1744]

This applies only to a 2-tailed test, correct? If it’s a right tailed test, how would we find the z score?
