[@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]

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.

[@judaato7923]

thanks dude

[@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.

[@khaibaromari8178]

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?

[@dr.olualbert6104]

I love it😍😍😍😍🤣

[@mahdiafrah7695]

thank u i did.

[@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

[@haneenhabis4252]

Sir , I really need your help , i have to ask you something important about research , i have a project that i should finish quickly , please help !

[@stephaniepalma3900]

What is the cheapest type of probability sampling?

[@tinotendamarongwe6412]

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

[@shilpag2294]

Sir how did you get 278 ? Which formula did u use ?

[@markkervintelen153]

Hi! I am currently doing a quantitative study on millennials in Cebu, but it seems that the respondents are not interested in participating in our survey. What is the minimum sample size that is recommended?
