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!

[@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]

[@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.

[@demelashhaile7250]

[@mrRubal100]

Hi Robert, is your course on Udemy "Research Methodology" suitable for people doing research in the medical field as well ? Will appreciate your reply. Thanks

[@khaibaromari8178]

+1 subscriber! 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?

[@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%?

[@Adnan_007_]

at 5:24 u said use sample size calculator. what's the equation for calculating it?

[@awambowe954]

Very interesting thanks, I have a question ❓ if am to conduct a study and my sample is to be drawn from households in a region of my conutry, what should I do

[@zeinabab6802]

Thank you so much, could you please issue a video about how to report analysis data. REPLY

[@mahdiafrah7695]

[@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
