Research Methods - Introduction

In this video, Dr Greg Martin provides an introduction to research methods, methedology and study design. Specifically he takes a look at qualitative and quantitative research methods including case control studies, cohort studies, observational research etc.
Global health (and public health) is truly multidisciplinary and leans on epidemiology, health economics, health policy, statistics, ethics, demography.... the list goes on and on. This KZbin channel is here to provide you with some teaching and information on these topics. I've also posted some videos on how to find work in the global health space and how to raise money or get a grant for your projects.
Please feel free to leave comments and questions - I'll respond to all of them (we'll, I'll try to at least). Feel free to make suggestions as to future content for the channel.

A true teacher is someone who reduces ignorance and reveals knowledge and makes the student (listener, viewer, what have you) reach a higher plane of understanding and doing. Greg, thank you for being an outstanding teacher and an inspiration!

[@gregmartin]

Thanks for those very kind words of encouragement! I really appreciate it!

[@anjanettesilvestre4331]

Thank you very much, SIR!

[@akinosuzuki9368]

It's refreshing to find a video explaining this without a script where the delivery is actually natural and not horribly robotic

[@gregmartin]

Thanks for the feedback Akino :)

[@whitneyb5816]

I am a Global Health graduate student, and I am so glad I found you. I've watched a couple before, but now I'm definitely subscribing!

[@gregmartin]

Thanks Whitney - I'm really glad to hear that you're finding the videos helpful. I'll be posting some more 'teaching' videos very soon (so watch this space).

[@nimishajoshi2148]

You are awesome,I am a microbiologist trying to wrap my head around the clinical stuff and this is such a booster!

[@raoufali6373]

Thanks indeed, Greg! It's really helpful what you present in this brief introduction about Research Methods I have gotten more interested in watching more videos of you relating to the subject matter!

[@gregmartin]

+Raouf Ali thanks for the comment. I'm going to create a few more videos soon - so watch this space. Happy day. Greg

[@foreveryoung782]

[@gregmartin]

MeMz Ash thanks for the comment - please feel free to let me know if there are other videos that you'd like me to do.

[@memzash9977]

Thank you sir! ^_^ Actually, Im studying this as part of research course at college, so anything regarding research proposal would be amazing 🙈🙈 Thank you again! :)

[@gregmartin]

MeMz Ash I have a video on how to do a research proposal on my channel - have a look around for it (if you don't find it let me know and I'll send you the link).

[@duongngoccongkhanh4711]

[@gregmartin]

You are most welcome Emmanuel! Glad to be of help.

[@rahafal-rifae7557]

You’re absolutely outstanding teacher, my professor is really uncooperative and always criticising us harshly & never taking in consideration what you did even if you give 10 times more of what he asked he would give you the lowest mark possible. I’m studying research methods on my own now because of his short comings

[@jayEel704]

This was extremely helpful! Thanks for posting!

[@learnwithSoumana]

[@Dellan42]

This video in particular was outstanding for helping my students grasp the difference between qual and quant. Keep it up.

[@gregmartin]

Thanks for the comment. Students do something find the difference between qualitative and quantitative research a little tricky. Glad to be able to help a little.

[@Dellan42]

Of particular use were the example questions, what why where etc. Spot on criteria tools.

[@suzannepenfoldtaylor6176]

I have been asked to teach research methods to a department of non-researchers. Wondering if i should just play your channel during a seminar and sit in the corner. Job done. You have done a fine job here!

+Surya Nigrat Datunsolang Thanks for the comment - I'm honoured that you'd use my video as part of your assignment. I hope that it goes well!! :)

[@SPMResearchwithDrRockBritto]

Awesome video..I am a great fan of Greg Martin..

[@tjmc1122]

Thank you for your informative videos. I'm trying to understand the research methods analyzing an article that is based on a collection of surveys and interviews, participants aged between 12-24yrs, observing how heavily they had been consuming alcohol in the last 30 days, from what I watched on your video, it's case study that's retrospective so it sounds right to me. Thank you Dr Martin.

[@gregmartin]

+tjmc1122 Thanks for the comment. Be careful that you don't confuse survey data with case control studies (not sure if you have). I have a video on case control studies. Essential, they use cases (that have an outcome of interest) and controls (that don't) and data is gathered (usually from a history) regarding their respective 'exposures' - good luck.

[@willd0g]

[@sandisiwemlotshwa714]

great staff, i have a question though. on types of studies, you mentioned the ecological. can you please explain a bit about the ecological fallacy

[@gregmartin]

thanks for the comment Sandisiwe Mlotshwa - if I understand it correctly, the ecological fallacy is making the mistake of assuming that because a relationship between an exposure and an outcome exists at the level of a large group (like at a country level) that the same relationship exist at an individual level (or in smaller group). It is a mistake to assume a causative relationship just because a correlation is observed.

[@bayosalau8054]

@@gregmartin This helps me greatly to understand the concept of ecological fallacy. I have an article to share and discuss with you on this topic. Kindly let me know how I can get it across. Thanks. Als @Sandisiwe, thanks for asking the question.

[@mudknot9000]

Lol @ the closed caption at 2:45. "clicking (unintelligable)" ...I turned on the CC to understand what you said, and the CC didnt know either. haha

[@gregmartin]

haha - I think that what I said was "collecting data in that sense" (sorry about the South African accent)

[@mudknot9000]

No need for apology! The information was still understood, just found that one part humorous. The video was quite helpful!
