Dear Brandon! Thank you so much for all your precious work! The world needs more people like you.

You are an amazing professor , thank you so much , you made it so easy for me to understand this categorical variable

[@kylemarnell1722]

I am always creating charts for our company and after watching this video, I now know not to use pie charts unless only two variables come into play.

[@MahdiSafarpour]

Dear Brandon, It is appreciated if you answer my question. When we are dealing with categorical variables, are we allowed to report our data as percentage! On the other hand, I wish to know if the relative frequency formula can be written as: (frequent of the observation/n)*100

[@danielarcher9175]

Great video on data charts

[@vsssarma]

Brilliant expression. Very well thought lecture so that student like me can learn easily. I am 65 and still learning. Missed out on Mathematics while doing 7 years of Mechanical Engg studies.

[@tylerdawson8594]

Very easy to follow. Didn't expect the pie charts shade, but i agree, They make me hungry anyways.

[@alonsom.donayre1992]

Hi brandon, where can we download the slides?

[@shalinshah9448]

Good Explanation.

[@kranthikishore9631]

It's good thanks

[@katietalbot8228]

Hi! Is there a way that you can collect data on 'Time Spent' as a categorical variable??

[@dgbene1]

Is relative frequency sometimes call normalization?

[@karlajohnson8017]

Straightforward good types

[@jesusfan3936]

I can't believe this videos are free

[@ElmoUnk1953]

Liked and Commented! Happy Algorithm! 😁

[@studyaim4240]

Please describe some methods to give weights to collected data. I have one body and various data about this body. Please how to weight these indicators.

[@nicholaspesek5902]

Easy to follow and good information. I will make sure to never use pie charts.

[@rickk3487]

Good video, easy to understand. Bonus that the instructor is a car guy and can pronounce Koenigsegg!

[@maysemguns]

How to measure weight categorical data ?

[@sparkysarkar7447]

Great

[@zorozene9639]

Hello Professor, Is there any way to get the slides you use in your videos. It will be quite handy and easy recall while saving a lot of times in making notes. If possible is will be good, if not no problem but at least reply so that I and others having same question will get an answer. Be Safe, Stay Healthy. Best Regards, Your Student

[@saikatsengupta7414]

I screenshot the slides.

[@gopivenkat2822]

Plz make videos on data science using any computer language

[@kishorekumar8080]

Same request from so many people for this one and only BRANDON

[@ishaafauziyaa8284]

Hope u add the other translate in other language.. My profesor give me examination from this video and I'm indonesian 😭 i rarely understood this video, cz i can't understand the video be good. :'))

[@Boxylon]

I hope you learn english soon, it will give you a much broader access to information throughout the internet! :)

[@danbailey1876]

I'm trying to find out where to start on basic statistics, when I start on descriptive statistics you start by saying "hello, and welcome to the NEXT video on basic statistics" making me think it's not the first one. Is this where I should start, or is there another one before it?? Another question do you have a book that goes with these videos, either your own or someone elses?

[@BrandonFoltz]

Hi Dan! Easiest thing to do is go my playlist page at kzbin.infoplaylists and then proceed from there. PL02, 03, etc. The playlists are in order as are the videos within each playlist. Let me know if you need any help finding things. Thanks for watching!

[@patrhiannongriffith810]

Brandon Foltz Actually FYI they pull up all out of order, it takes some messing around to find them all.

[@hahnsolo46]

What if you really love pie charts?

[@danbailey1876]

Just to be clear, I'm trying to figure this out so I can use these videos to supplement a Stat Methods I class.
