In this question we have given, subjects are randomly assigned to four groups.
00:06
Each group is placed on one of the four special diets.
00:11
After six months, the blood pressure of the group are compared to c if the diet has any effect on blood pressure or not.
00:22
So, using this information, we have to answer four questions.
00:28
In a we have asked that classify this study.
00:37
So here we have to check whether it is an experimental or it is an observational.
00:44
So for that first we will understand what is the experimental study and what is the observational study.
00:52
So first we will discuss about experimental study.
01:01
So here, here typically different groups are made and comparison is done after setting parameters and in observational study data from already happening events.
01:51
Are taken and study is done.
02:00
So here in this situation groups are made and the parameter is set as diet to compare.
02:23
Hence we can say that it is experimental study...
