The correct answer to this open question is the following.
Unfortunately, you forgot to attach the options for this question. However, trying to help you we can comment on the following.
A researcher wants to find out if spending an hour outside every day promotes increases in mood and mental health. To study this, the researcher selects individuals in a specific age group and divides them into two groups. One group is told not to spend persistent time outside. The other group is instructed to spend an hour of uninterrupted time outside. This model would best reflect an Experimental design.
Let's remember that in psychology or sociology, experimental design means that the people who participate in the experiment are grouped into different teams or sides
Most of the time, researchers split the participants into two groups because one group is the so-called control group and the experimental group. All the variables are introduced into the experimental group to find the results.
Answer:
to determine the casual relationships between social elements (option b).
Explanation:
When we are talking about qualitative research, we are talking about research that deals less with calculations or even no calculations at all (or we can say that it deal less with numerical values), and this type of research involves more or seek to extract information more from how people behave. Qualitative research can be in form of questionnaires, observations and so on.
And, talking about the quantitative type of research we are talking more about the collection of data that deals more with calculations (numbers).
So, the common goal of qualitative and quantitative research is that of option 'b'; ''to determine the casual relationships between social elements".
It is small only if you are not involved in such an incident. If you are, then it is extremely large.
