Answer 1

- Experimental studies are those in which an intervention is done and participants enrolled in a study are randomly assigned to experimental or control group

- Quasi-experimental studies :-

Participants are not randomly assigned to groups

Investigator does not have control over assignment or timing of intervention.

- Descriptive studies are the observational studies which deals with frequency , distribution , surveillance , time trends , geographical patterns .

1) Identify the study :-

1. Descriptive study because in this the researcher is analysing the cardiometabolic risk factors among adults with obesity or overweight in 10 geographical diverse regions from 2012-2013.

2. Experimental study because there is randomly assignment of the patients into control and experimental group .

3. Descriptive study because it's a kind of surveillance

4. Quasi-experimental study because there is no random assignment of subjects . It is done according to convenience.
