How to determine sample size for beginners. A quick guide to using Epi info Mobile (Episode one)

In this video, I quickly demonstrate how to determine the sample size for beginners. Here we compute the sample size for cross-sectional studies when the outcome variable is a categorical variable. Very good for researchers, residents, reviewers, examiners e.t.c

Answer to the exercise you gave is ; 234 doctors is the minimum sample size that Doctor Maryam would be needing to carry out her studies. Thanks a lot for sharing this video sir. This my first time of working with this software, I didn’t even know it could work on phone ( I installed it on my system a long time ago,but up until now, I’ve not been able to figure out how it work, I’ll be needing it for my final yr project analysis, which is why i installed it in the first place, but until now , I don’t know anything, I’ll just open the epi info, stare at my laptop screen for a while and close it back, cause I couldn’t make any sense of it). This is really explanatory , u made it so easy and straightforward. Thanks a lot. It’s a good start to keep learning how to use the software.

I request to know how I can get parameters to calculate a sample size for a case-control study using epi info. Thank you in advance.

[@PublicHealthResources]

My man DEUS, I will be releasing the video very soon God willing. But all you need is just the understanding of what a case control study is and then the parameters can be obtained from previous studies. You basically need power of your study which can be 80% or more and the from literature you get the percentage of cases exposed and percentage of controls exposed. It’s easy😊. I have a very interesting video with lots of examples coming out this week. Please kindly stay tuned sir. Thank you

[@IrfanHanif-tp9co]

thanks for explaining but the app also shows two more things which u have not explained one is design effect and the second one is clusters what to do with these .kindly explain

[@EpiInfoforRookiesE4R]

Great question Irfan. This video is only for computing sample size for a cross-sectional study when the primary outcome variable is a categorical variable. So the area of the app for this doesn’t have design effect as well as clusters. But I will try to still explain it here. For design effect, anytime in which you plan to use a cluster sampling technique in your research to select respondents then you need to adjust your sample size by a factor due to this design (cluster sampling design) this is known as the design effect. It is simply a way to buy back the power that we lose when using a cluster sampling technique. God willing, I will cover this in full in another video.
