Standardizing Normally Distributed Random Variables (fast version)

I discuss standardizing normally distributed random variables (turning variables with a normal distribution into something that has a standard normal distribution). I work through an example of a probability calculation, and an example of finding a percentile of the distribution. It is assumed that you can find values from the standard normal distribution, using either a table or a computer.

I appreciate the enthusiasm in your voice, its appreciated, and of course the video is excellent. Thank you for taking the time out to make it sir.

You can find that using software or a standard normal table. I have videos outlining how to find percentiles using the standard normal table. (There are 2 main types of table, and I have a video for each one.)

Dude, your videos are some of the most well-presented math videos I've seen (and trust me, I'm in 4th year eng, I've seen A LOT) You're a real gem <3

[jbstatistics]

Thanks! I'm glad you like this video. I've got lots more stats videos, and I'll definitely be adding content for some time.

One word about your presentation: SUPERB!!!  Thanks a lot, you are the best tutor to explain this!

[jbstatistics]

Thanks for the feedback and compliment James. I am just doing my videos the way I think is best. What I think is best changes a little through time. I had a different vision in mind when I first started making these than I do now, so I've changed how I do things a little. I'm glad you like this video. I do too.

My teacher spend 1 hour of the class trying to do what you did in less than 10 minutes, truly excellent work. You deserve more views that this!

[iamlightboo]

you have no idea how much you've helped me omg. i've been almost failing stats because i couldn't understand it until i found this channel #bless

[Chrysaries]

I like the speed of this video! Towards the end it sounds like you're in a game show about explaining statistics before being swept down into water by a moving wall, but it's still calm enough to understand without feeling stressed. I guess it's more akin to a commentator's change of voice when a goal is approaching.

[jbstatistics]

You're welcome, and thanks for the compliment! I'm always happy to be of help to my friends in the UK.

[FB-trkf]

Feel really proud in what you're doing. Every view that you ascertain through one of your videos, motivates an individual to carry on and learn more. You've really made learning fun and easy.

keep up the wonderful effort.

Sir ..could u explain how the z value is 1.28??

[Tlanification]

Bless you sir, your enthusiasm for stats is so infectious, I think i finished my entire semester's worth of content in a single weekend.

All thanks to your videos.

[jbstatistics]

You're welcome, and thanks for the feedback. Due to popular demand, I've slowed down a touch on my recent videos. But I still try to make them a little quicker and much more concise than what I see out there.

Love that you're using a higher tempo than usually man. Never really understood the point of talking slowly when Youtube has the ability to paus and rewind. Thanks man.

[realisticlevel]

Thank you for having me enjoying my statistics course because of this beautiful and useful lectures! You deserve the best

[peiyan]

For 0.521 should we look at negative z-score or positive?

[saurabhprakash]

You are a global brand. I like your enthusiasm in improving your presentation. Just noticed the sudden change in emphasis. The material is top notch as usual. Many thanks.

9 years later and still helping me feel better about my final tmrw, thank you

[sonyxxmunions]

I do school online, and even the lecture videos and textbooks could not teach me the way you just did. I appreciate you making this. You just helped me pass my class.
