I want to thank the person who is explaining all these Research Techniques very easily with simple examples. I wish to see you posting more of such videos with very simple examples. Thank you very much.

[@originalmisstee]

Wow, I don't feel dumb anymore. You made this so easy for me to understand. I can walk into my exam with confidence! Thank you!

[@JezabelleTIC37]

You're the best! You presented it logically and explained it excellently. You rescued me from my insanity doing my research......Thanks and I subscribed! God bless you.

[@margaretmitchell365]

The explanations are awesome. It real gives us clarity. It makes it seem so much easier to understand!

[@kcmakhubele7295]

Lovely , enjoyed the explanation . Just for those who are not sure how to get sample size from the 3 different population / strata ~ take sample size (200) /population size (1000) = 0.2 x each strata of 500, 800 and 200 and you will get the corresponding 100 , 160 and 40!

[@lefumiya1777]

Thanks for this... I'm done with chapter 1 of stats now. I felt so dum for the past 2 months

[@mercybarmao8163]

I was preparing for my exams and I came across this simplified and easy to understand teaching, you are actually a talented teacher, thank you so much 🙏🙏

[@lukaskahare2828]

Well presented in a simple way and understandable

[@sin8554]

I’m a Counselling student, and in our field, understanding research methods is necessary too.
It was pretty information-heavy for me, but thanks to you, I’m beginning to really understand the key terms behind research methods, sampling etc. Thanks, man.

[@thiduyenbui9261]

Could anyone help me to answer this question please? . are stratified samples simple random samples? I get a bit
confused at the "Stratified sample" method. It doesnt sound that we are
making random samples because if we break the population into smaller
groups and pick randomly, for example we have 5 levels of education and
each level is one subgroup, then we prioritize to have samples which
include all levels of education. It means that you miss out samples
which maybe only contains 4 or 3 levels of education. In the beginning,
we have a very clear definition for " a simple random sample is EVERY
SET OF n individual has an equal chance of being sampled", in the
stratified sample we dont let every set has an equal chance of being
sampled.

I was thinking do we need to weight the interviews based on population of each stratum at 10:58 or the proportionate stratified random sampling is enough?

So do we just guess the confidence level and the confidence interval or there's a way to get a 95% and a 3%?

[@jobellmathew8915]

[@empaulstube6947]

1:54 Can I request for a citation about this statement which says that if the sample size is less than 50, we should opt to use non-probability technique?

[@venus3173]

You need an n of 50 to use statistical inference procedures used with probability techniques ! Hope that helped
