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

[@doppelplusungutmensch1141]

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. :)

[@JohnPaul-v2f]

amazingly cool

[@lakbh]

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

[@devendraraj1339]

Yeah

[@empyrean-jamelgreaves8034]

Yeah, I got D in school. Because of this guy, and I mean this guy ALONE, I perfectly understand most master degree level. I’m actually going through this series again for my brother so he can smash his teachers to pieces before he even begins lol. They teach math, honestly, so incompetently it’s mental. And when kids fall behind because they don’t understand something (likely due to the teachers poor explanation…) they couldn’t care less. Make sure to check out his physics stuff too.

When you're motivated of something and want to watch KZbin to learn you will actually learn something

[@basketguitar9768]

​@@empyrean-jamelgreaves8034right? The fact that me and you learned more from the internet than actual math class is insane.

[@ceegae1670]

​@@empyrean-jamelgreaves8034 I fr CRUSHED kids in my class who brag about how hard they study for the midterm physics test with just 15 minutes watching Dave's video on the topics I needed...It was the craziest feeling ever for me. The fact that I can catch up with them that quickly from understanding the concepts rather than mindless memorization was mind-blowing. Really shows how incompetent some teachers are

[@franklinquio]

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.

[@kai-zd8xm]

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

[@ultimatereasoning7056]

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!

Good explanation

[@machinex3646]

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

[@ProfessorDaveExplains]

There really wouldn't be one since none of the values repeat, either that or maybe they all qualify as the mode? I'm not sure how it works in such a case.

[@machinex3646]

@@ProfessorDaveExplains Ok professor.

[@MohammedAliIZGUA]

Based on the definition of mode: "A set of numbers with two modes is bimodal, a set of numbers with three modes is trimodal, and any set of numbers with more than one mode is multimodal. [...] The mode is not defined when there are no repeats in a data set."

[@luke-rh8wc]

Thank you

[@jinooh9241]

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!

[@tarakachroo2163]

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 :)

[@lucyhennessy9324]

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

[@TechSciWiz]

Thanks, Prf Dave Your explanation is awesome!

[@cosmosinhindi]

Your lecture is helpful for me understand basic

[@gabijagorobecaite8037]

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

[@ProfessorDaveExplains]

Not yet, at some point I will do a whole series on it though!

Sir, Do you have any videos about probability and statistics in youtube?

just check my math playlist. it's around the 70th or 80th clip.

[@shanawass8629]

Isn't median 9.5? Cuz the middle terms are 8 and 11 and the sum is 19 and when divided by 2 the median becomes 9.5, is it right? If wrong correct me.

[@Atrobyte]

No, because the numbers in the set are odd and therefore has a middle number so u can just use that

[@Adam-lf1hz]

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

[@rodger3352]

haha cooool !

[@anthonystark6215]

Thanl you, Professor!

Range=59 Mean=20.222 Medium=8 Mode=7

[@pclindberg4423]

whats the mode for 1 2 2 3 3 7

[@m_r-ock6508]

i think there can be more than 1 mode number so its 2 and 3 but i might be wrong

[@Qwasieee_P]

Bimodal, 2 and 3. It can also have no mode {1,2,3,4} or multimodal {1,1,2,2,3,3} -> 1,2,3

[@SonaStepanyan-q3q]

which is the mode if there are two different numbers with the same frequency in the list?

[@MainStu.]

Both of those number

[@yukinocodm131]

Moving on algebra lets go

[@alexci3563]

can there be two mode numbers ?

[@paulahernandezaulet7401]

Yes,

[@MrA-ou1xd]

Yes

[@caribbeanman3379]

What would the mode be if there are no repeating numbers in a set?

[@MainStu.]

There's no mode then

[@caribbeanman3379]

@@MainStu. Or we can take the mean of the 2 numbers that are closest to each other in value (least difference between them)?

[@MainStu.]

@@caribbeanman3379 that's what u would do for the median, but still there's no mode

[@brandonlamontcooper8141]

why is the range from 0 to 7, but when we check comprehension its not the greatest number? the largest number minus the smallest?

[@AmataSora]

What if the given sets of numbers are 2, 5, 7, 7, 8, 11, 11, 49, 61? What will I answer as the mode? 😭😢😱

[@СергейМакаров-ч4л6е]

Both 7 and 11

Man... I just relearned the math they thought us from grade 1 to grade 6 in like a few hours

[@chourouk-gr9qg]

Well

[@pclindberg4423]

what if there is two modes

They are both the modes then

[@UnknownUser049]

add the two modes then divide it by 2 but i guess this comment is too late

I didn't get median ..................

[@VliamirNoobin]

Don't worry, I gotchu> So think of a CEO who earns 1,000,000 doillars a year while the Janitor earns 10,000 dollars a year. If we think of a company with 1,000 employees, wouldn't the "average" salary be spiked up? To make this simpler, let's scale it down. CEO earns 1,000 Manager earns 500 (1) Senior earns 300 (2) Employee earns 100 (4) Interns earns 50 (5) If we arrange them in ascending order, with the parenthesis meaning how many of them are, let's try. 50, 50, 50, 50, 50, 100, 100, 100, 100, 300, 300, 500, 10,000 Find the data point at the center which would be 100, 100 is the median(middle). But if we do the mean(average), 10,750/13, would be 826.923076923, which is not what you're looking for. Applications of median is useful especially if you want data points like the CEOs not to affect the "average" you're looking for.
