Measures of Dispersion: Formulae and Examples | What is dispersion with Examples | Sample size

To learn all concepts in basic statistics in the simplest language and examples visit vijaysabale.co/statistics
Hello Friends,
In this video, you will learn Measures of Dispersion with practical examples.
This video consists of the following topics:
✅ Population, Sample and Sample size
✅ Methods of sampling and their use
✅ Representative Sampling
✅ Sample size for some important charts
✅ Measures of Dispersion
✅ Range
✅ Variance
✅ Standard deviation
✅ Coefficient of Variation
✅ Display Descriptive Statistics in Minitab
I have explained the importance of “Measures of dispersion” and detailed procedures to calculate them with an example, mainly with the help of Microsoft Excel and Minitab.
I am sure, you will like it.

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 !?!

[@fatimasaleh9269]

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

[@learnandapply]

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.

[@AravindHan008]

so Measure Of Dispersion is standard deviation and other parameters that shows how the data is spread from the mean ?

[@learnandapply]

Measures of dispersion are the metrics that describe the variation in your data.

[@anushkasrivastava3286]

Sir standard deviation mai 9-1kaha sai aa gaya

[@learnandapply]

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.
