In this video, Dr Greg Martin describes how randomized control trials work and how they deal with confounding variables. This is episode three in a series of videos looking at epidemiology, research methods and study design in the context of global health.
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 YouTube 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.

Students often have difficulty classifying quantitative research designs. In quantitative research, designs can be classified into one of three categories: descriptive nonexperimental, quasiexperimental or experimental. To identify which of these designs your study is using follow the steps in this video.

Students often have difficulty classifying quantitative research designs. In quantitative research, designs can be classified into one of three categories: descriptive nonexperimental, quasiexperimental or experimental. To identify which of these designs your study is using follow the steps in this video.
First, ask yourself if the researchers did anything to the participants. More specifically, was there an intervention?
…If the answer is yes, there was an intervention, then the study is either a quasiexperimental or experimental. I will tell you how to decide in a moment.
If the answer is no, the study is descriptive nonexperimental. Sure, you could be more specific in the description of the design, but for the purposes of grouping your research in a literature review this label is often sufficient at an undergraduate level.
Descriptive nonexperimental studies may also be called observational. Some examples of more specific labels include case control, cohort and correlational studies. …
To find out if the design is experimental ask yourself if it is a randomized controlled trial. Randomized controlled trials are considered the gold standard or \”best\” possible design (in quantitative research). You may also hear randomized controlled trails referred to as true experiments. However, in the real world it is difficult to conduct a true randomized controlled trial in many situations, which means that a lot of studies are done that are not classified as randomized controlled trials.
Randomized control trials have three key components: a random sample, a control group and an intervention. If your study is truly a randomized control trial it should say in the abstract and/or the methods section of the article. If it doesn’t say then it is likely that the study is either descriptive nonexperimental or quasiexperimental. You can tell the difference by looking into the methods section further.
…If there is no control group than the study is quasiexperimental. A control group is a group of people that enter the study but do not receive the intervention under study. Instead, they are used for the purpose of comparison.
If the sample was not randomized properly or adequately or even at all then the study is also quasiexperimental. You may also see this type of study being called a nonrandomized trial. …
Sometimes I see students that are confused about the study design because of terms that relate to the length of time the study was conducted or the sampling process. …
Terms like crosssectional and longitudinal tell you how much time the study was conducted over. Cross sectional means that data were collected at one point in time. Longitudinal means that data were collected over a long period of time. These terms alone will not tell you if the study is descriptive nonexperimental, quasiexperimental or experimental. If you use these words to describe your study design in the absence of one of the labels we discussed in this video you will not have given your teacher enough information about the study design to properly classify it.
Other confusing terms often relate to the way samples were collected, like convenience sampling. Convenience sampling means that the sample was readily available or accessible to the researchers. This term will give you the hint that the study does not have a random sample and is therefore not a randomized controlled trial, but you still need to classify it further as descriptive nonexperimental or quasiexperimental.
To decide how to classify the design of a study you are looking at, follow the steps outlined in this video. Ask yourself the following three questions:
Was there an intervention?
Is there a control group?
Was the sample random?

Randomized Controlled Trials (RCTs)


A randomized controlled trial (RCT) is an experimental form of impact evaluation in which the population receiving the programme or policy intervention is chosen at random from the eligible population, and a control group is also chosen at random from the same eligible population. It tests the extent to which specific, planned impacts are being achieved. The distinguishing feature of an RCT is the random assignment of units (e.g. people, schools, villages, etc.) to the intervention or control groups. One of its strengths is that it provides a very powerful response to questions of causality, helping evaluators and programme implementers to know that what is being achieved is as a result of the intervention and not anything else.
This video summarizes the key features of an RCT. For details, please read Brief 7 at http://www.unicefirc.org/KM/IE/
