if a resercher is looking for a certain sample such as "women who smoke" is this non-probability? as well since its is a specific group he's looking at would this be convenience sampling, or purposive sampling?
@@EvanOrtlieb1 If the targeted population is 'women who smoke', then the researcher selects every third woman who is a smoker, then wouldn't this be systematic sampling?
@@EvanOrtlieb1 a lot lol but I think at this point it is trying to figure out when a non-probability sampling method is warranted in comparison to a probability shampling method. Is the sampling method up to the researchers discretion or are there guidelines to follow
I would recommend doing random if possible but most of the time, it isn't feasible. So often times people go w convenience or purposive. It really depends upon the end goal (whether a class assignment, a peer reviewed paper, an industry research project,etc) and whether you seek generalizability across different settings.
Thanks for preparing and uploading this lecture video, very helpful
Amazing
full content,clear explanation and easy to understand
The video has clear explanations. thank you
Thanks for the video really helpful to slow learners when it comes to biostatistics🙏
Thankyou.the video was very helpful,if you could accompany with every single formula it could be much better.
Thnks u r really helpful
Thank you sir Itx very helpful for me💕
It's really nice work sir 👍👍
Thanks for your lecture

That would be a form of purposive sampling...a non random sample

Very good lesson
Am very grateful sir.
Thank you so much it was very helpful
I love that😍😍😍😍😍
thanks for preparing this well organized lecture
5:06 muestra intencional no probabilística que sí es evidencia válida para fines descriptivos no inferenciales
Isn't there a snowball sampling in the non probability?
Snowball sampling is indeed a form of non probability sampling. It can take on different shapes but is useful to some research.
nice presentation and discussion
great work
Have an exam in 30min😂
How was your exam😅
yea im not passing this exam
what part is the most challenging for you?
