How to Calculate Standard Deviation of Continuous Data ? | Grouped Data Direct Method

Hi Friends,
In this video, we will learn how to calculate the standard deviation of the continuous frequency distribution by direct method.

Correction: 5:27, Pls note Variance = 160 not 180 , Hence Standard Deviation = 12.64

A few corrections -
4:29 - it's 1152, not 1154...have done calculations with 1152, but written 1154 by mistake !! Something you should avoid 😅
5:30- variance is 160, not 180 !!
Standard deviation is 12.64

Couldn’t understand anything from others but this video helped me a lot, very fantastically explained and straight to the point

[bhupesh]

Hey this was one of the best videos on Standard Deviation on YouTube, straight to the point, fantastic super clear and simple representation and excellent explanation!!

kudos to you!!!

This is my 4th continuous video that I watched... wonderful work ma'am.. keep helping us by uploading more videos

[aditii]

U have a very nice and calm voice!! Makes learning less stressful

[gyfr]

It's 160 in the end mam
And the video is very helpful. Thank you

[pksgkri]

The video is definitely useful. There is an inadvertent mistake. Instead of 180 it should have been 160. Thank you.

I have been really struggling as my lecturer only posts videos and is very rarely online to talk to, you have shown me exactly how to do it so much quicker

Thank to you ma'am very helpful video ❤

​ @EnjoyMath When you are calculation St. Deviation how do you determine your denominator? Can you please explain when we are to use St. Deviation formula of sample data (n-1) vs St. Deviation formula of population data ?
Thank you for your time!

[SurajDas-ykzf]

Very helpful video to understanding the standard deviation . ♥️♥️♥️

[ramyayanumula]

Thanks mam it is wonderfull teaching, super understanding ❤

[asshravanishravani]

Wonderfully explained the concept so crystal clearly❤😊

[apoorvadash]

Tysm for all the efforts. Is the denominator supposed to be N or N-1, different sites and videos show different formulae. Please resolve this doubt.

[Abhishekaks]

Thank u so Mach mam this video help me to calculate solution🎉🎉🎉🎉🎉🎉

@Enjoymath
What if summation of frequency (N )is less than 30.
the formula for standard deviation would remain the same ?

[vaniesrilalithamageswaries]

In some video they are dividing it by N-1 which one is correct madam?

[akku]

You explained it very nicely.got it in one go😊

[souloflaughter]

i was wondering if i could use this method which is in root we have Σfx(x)-(xbar)square/Σf

[mentalff]

160 Mam right answer and last answer is 12.65
