You are such a great teacher , you teach very nicely..making LSS an interesting topic

Thanks 😊

Hi Mohith, Your videos are great. You explain everything perfectly without beating around the bush. Your explanations are very practical. Vast majority of six sigma professionals are theoreticians you are the

Hi Sir,
Nice video, I will try to perform it.

Hi Mohith, Your videos are great. You explain everything perfectly without beating around the bush. Your explanations are very practical. Vast majority of six sigma professionals are theoreticians you are the most practical six sigma professional I have ever came across. Keep up the great work.

Thanks 😊

Absolutely perfect and easy to understand! Thank you!

[@khushboogupta-oy8sn]

Excellent video..nicely explained

khushboo gupta much thanks 🙏

[@jatinab]

This is really good explanation Sir..i would now be able to leverage this video in doing sampling exercise for my projects..Thanx alot..

[@mohitsharma34]

Thanks !! I am glad it is helpful

[@ishwarpawar7180]

Thank you Mr.Mohit, great sharing

[@mohitsharma34]

Much thanks 🙏

Good one.... Informative video..

Thanks Dilshad !!

[@fitat4049]

Excellent video !

[@mohitsharma34]

Thanks 🙏

[@parinitajadhav3852]

Sir could you give me some real life examples of sampling techniques mentioned in you video

[@saurabhidea344]

Hi Mohit, does this formula of sampling be used for transaction monitoring aswell.

[@mohitsharma34]

Yes.

[@mohitsharma34]

If you’re trying to take a sample for Quality check then you should use the same formula....

[@digitalravi]

Sir, Thanks for the great video. what number will it change from 1.96 If i need CL as 99% instead of 95%?

[@mohitsharma34]

At 90% confidence Z 1.65
At 99% confidence Z 2.576

[@rahulmaurya-qi4vy]

Hello Sir, What exactly you mean by " As standard deviation increases large sample size is needed to get reliable result" . Can you share an example where in Std deviation is increasing

[@mohitsharma34]

When standard deviation increases means variation is increasing in the process. So correctly interpreting the population with smaller sample size is not possible.

[@rahulmaurya-qi4vy]

@@mohitsharma34 let's say the entire population is 1000000. So in this case do we need to take 30 data points from 1000000. And how to check increasing variation in this case.

[@nandalalsahis2472]

Can I use n=N/1+Ne ^2 wherein e =0.05 to determine sample size of given population

[@alkaahmed32]

Sir, as far as I know there are 3 types of sampling i.e Random, Stratified and Segmented. Can you please explain Segmented one.

[@adtgrh]

Can we use this formula to draw sample from discrete data

[@mohitsharma34]

There’s a different formula for discrete. You can also use google sample size calculator.

[@shafikhan100]

Hi Mr. Mohit, one question, is abandoned calls in contact center can be considered as discrete data?

[@mohitsharma34]

If you are counting them as no of calls abandoned then yes.

[@shafikhan100]

@@mohitsharma34 so if I am not counting, is there any scenario , it can be considered as continuous data?

[@akakarun8]

Hi Sir, in a BPO industry mostly the transaction monitor is happening where there are set of quality parameters and each parameter is assigned with weightage (2/5/8...) and we need to select Yes/No for each parameter and we get the score.
For such kind of transaction monitor, is your formula is applicable for calculating sample size. If not, what formula is applicable?
Thanks in advance

[@mohitsharma34]

You can divide your transactions in different subgroups and take 30 samples per sub group.

[@iamharry18]

At 4:13, the calculation of Sample Size is incorrectly shown as 32 for 95% Confidence Level, Margin Error of 2 and Std Dev of 8. Per formula, it should be 61.46 or 62.

[@mohitsharma34]

Thanks for watching it so closely but if it is more than 61 then you will take 62 only. Isn’t it?

[@iamharry18]

@@mohitsharma34 62. But the video shows he number as 32 which is incorrect representation. Rest the video explains the concept very clearly
