study to examine how poeple respond to pictures of faces with different racial features.

The experimental design is when the experimenter isolates and controls all the variables

excpet one, he makes sure that variable is the only one causing the desired effect. The

The independent variable, which is the variable that the researcher is manipulating, is

computer program that he created that will randomly generate the faces as each subject

comes in. In this study the researcher used random assignment as the the subject would

come in the the room. Random assignment is went the experimental and control groups

a non-systematic and randomized way. The way he did this is by not telling his research nor the subjects knew which order they were going in.

The team of researchers that found that the more time students spend interacting

with technology, the less empathy they show towards other by doing a correlation

study. Since many students already use technology a lot this was would be easier to use.
The students increased use of their devices is one variable and their lower empathy

towards other is the second one making a negative correlation. A negative correlation is

a correlation indicating that the variables simultaneous in opposite directions.

The second researcher that tried to determine that the more social support and

a patient has the better the outcome of their disease treatment did this through

Replication.
