Hello sir, I am having airborne dust concentrations data as PM10, PM2.5, PM 1 . These data was taken before and during dust producing work in a civil construction site. N=5 How can i compare these before and during operations data ? It seems that there is percent variation in dust concentrations in atmosphere between before and during operation data. e.g., PM 10 ( particle size less than 10 microns) is sharing 40% of total airborne dust, and PM 2.5 ( particle size less than 2. 5 micron) shares 10% of total airborne dust. During machine operation: PM 10 shares 60% and PM 2.5 10% only. It seems that PM 10 share is increased due to that machine operation? Which test is suitable for analysing these type similar data for discussion ? How to use statistics? Any comparison among these particle sizes? thank u.
@@learnandapply I need help 🙋🏻♀️🙆🏼♀️In Standard deviation!! There are tow formulas!?!? I mean one formula we (divided by n-1 ) And the other one we (divided only n ) How i know when to use those !?!
If you going to calculate the standard deviation for population, then you need to use the formula with sigma, and for sample, you need to use the formula with s.
Excellent teaching sir it's useful for exams 💐💐💐👌
That's great!
Thank you so much for your valuable comments and appreciation!
Good explanation very helpful in exam...

How to use statistics?
Any comparison among these particle sizes?
thank u.
Nice content,i understood everything. Thank you
Thank you so much for your kind words and valuable comments.
so Measure Of Dispersion is standard deviation and other parameters that shows how the data is spread from the mean ?
Measures of dispersion are the metrics that describe the variation in your data.
@@learnandapply thanks :)
nice video
Thank you for your valuable comments.
Please share it with your friends and colleagues..
Nice class sir
Thank you for your valuable comments and appreciation ☺🙏
This is life saver, thank u sir 🥰🥰🥰

@@learnandapply I need help in variance!?! When i have to use s^2 and Sigma^2!؟!؟
There are different between them!?!

@@learnandapply 😀😀thanks 🥺
Well explained, keep it uo
Thank you for your valuable comments
really amazing explanation and fantastic style of video! keep going~thanks very much

Where can I download minitab
Here is the link for a 30-days free trial:
www.minitab.com/en-us/products/minitab/free-trial/
Nice video👍,but please remove background music its distracting
Sure, thank you so much for your valuable comments and appreciation!
Background music disturbs the learners!
Extremely sorry for that. Yes, it was the problem with the old videos on the channel.
What is the editing video app of this vid ?
It's Videoscribe.
Sir hindi m vedio v provide kijiye
Thank you so much for your valuable comment. I am not good at explaining it in Hindi.
Can you kindly add subtitle 🙃
Yes, I am working on it. It will be added by today. Thank you for your valuable suggestions. 😊🙏🙏
Sir standard deviation mai 9-1kaha sai aa gaya
9 is the total number of readings or observations and (9-1) is degrees of freedom, which is one less than the total number of observations.
How to use Excel in examination 🙄
Please use these formulae.
Subtitles please. I'm having an extremely difficult time understanding you...
Sure, I will upload that in some time.
Thank you for your valuable comments ☺
please correct your pronunciations. For n , s . it was so confusing
Thank you for your valuable suggestions!
not a great explanation for intro
Ok, thank you for your valuable comments.
