This type of quantitative research aims to examine the effects of a treatment dicotomic variable (values 0 or 1) on a certain dependent variable. In this case:
- the treatment variable: living together with the couple before marriage. It is dicotomic because it equals 1 when a couple lived together and 0 when one did not.
- the dependent variable: happiness during the marriage
The aim will be to assess whether there is or not a casual relationship among these two variables. In order to so, control and treatment groups should be observed. The treatment group would contain couples who experienced the treatment, hence (living together before marriage), while the control group would be composed by couples who did not undertake the treatment.

The more the heart muscle fibers are stretched, the harder the heart will squeeze. The heart can compensate for quite some time by squeezing harder. However, squeezing harder can cause the heart muscle to thicken over time.
An overly stretched heart muscle, known as dilated cardiomyopathy, can affect a person’s end-diastolic volume. This condition is often the result of a heart attack.
Also another heart condition that changes end-diastolic volume is cardiac hypertrophy.
When someone is studying how prior exposure affects color preference, they are aware that color preferences are also influenced by ethnic background. They could enhance the sensitivity of their research by focusing on one ethnic group. This method has a problem in that someone would have to use several levels of prior exposure to ensure they were getting an accurate picture of the connection between preference and exposure. Hence, the correct answer is C.
<h3>Understanding Color Preference</h3>
Color preferences are the tendency for a person or a group to prefer particular colors over others, which includes choosing a favorite or a traditional color, in color psychology. Human color preference is influenced by brain receptors, according to research. We typically prefer specific colors based on our surroundings, their value, the weather, and the quantity of light reflected from various things, and we may be interested in one color for a long period of time or lose interest in another. Numerous psychologists believe that because our brain perceives colors with logic, each color affects humans differently.
