Analyzing Sets of Data: Range, Mean, Median, and Mode

What does the word "average" mean to you? There are a lot ways we use that word, and even in math, it can imply a few different things. If we want to summarize a set of data in a meaningful way, we can talk about the mean, the median, or the mode, and one might be more useful than another in a particular context. So let's learn what these are all about!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Just to explain it for non-Americans (and there are quite a lot of them):

July 4 is the national day of the US, that's why in an average American town fireworks will likely be much higher that day than usually.

I'm just saying since some people might wonder why that sample size in July seems so weird. :)

wtf man, i failed in maths my whole life and this guy explained everything in just 5 minutes to me..

Professor Dave, I have completed the first part of the Arithmetic course, I am so glad you have uploaded these videos, they are so helpful. I will now go over Algebra 🎉

[tcysafta.]

I finally really understand elementary math thanks to these videos. Thank you professor Dave!

[dragonfire_bane]

Absolutely fantastic I cannot imagine getting ready for collage without these video's I hope I can grasp it enough for collage.

day 3 of reviewing math lessons, concise as always. you have my gratitude for these tutorials, professor dave! :))

[ultimatereasoning]

I don't find the words to thank you for giving me an opportunity to learn what I regarded before as an impregnable task to be tackled!

I can't believe a five minute video taught me something ive been stuck on for months

[nejatahmed]

Great explanation as usual. Thank you!

Professor, if {1, 2, 3, 5, 6, 7, 9} Could you please tell what will be the mode here?

[thegreatcasts]

Thank You professor this helped increase my grade in math

[lucyhennessy]

do you have a video about standard deviation? if not do you think you could make one one day

Hi Professor. Thanks for the video! I wanted to ask how do you go about finding median and mode when you are given a wide range of data. i.e. one that you wouldn't be able to visibly identify, one that consists of a thousand data. Would you have to use a specific program for this or can you mathematically find median and mode as you did in this video in a short period of time? Thanks!

Your lecture is helpful for me understand basic

[gabijagorobecaite]

Amizing as always. Professor Dave, do you have any more videos on statistics?

[tarakachroo]

I got quite a kick out of the elevator music during the comprehension part of the video. This was an excellent resource for my child who is learning this material now :)

There was a little rhyme that I learned in 5th grade that helps with remembering the mode, it goes “the mode is the number that occuuurs the most!”. There was one for the median and the range and all that but I forgot them

Thanks, Prf Dave Your explanation is awesome!

[deadlord]

İf you were my teacher, i would have already been maryam mirzakhani, love you professor dave!
