This is still a correlation. It is like an "inverse" correlation. The word "negative" is a label that shows the direction of the correlation.
There is a negative correlation between TV viewing and class grades-students who spend more time watching TV tend to have lower grades (or phrased as students with higher grades tend to spend less time watching TV).
Here are some other examples of negative correlations:
1. Education and years in jail-people who have more years of education tend to have fewer years in jail (or phrased as people with more years in jail tend to have fewer years of education)
2. Crying and being held-among babies, those who are held more tend to cry less (or phrased as babies who are held less tend to cry more)
We can also plot the grades and TV viewing data, shown in the table below. The scatterplot below shows the sample data from the table. The line on the scatterplot shows what a negative correlation looks like. Any negative correlation will have a line with that direction.
Participant GPA TV in hours per week #1 3.1 14 #2 2.4 10 #3 2.0 20 #4 3.8 7 #5 2.2 25 #6 3.4 9 #7 2.9 15 #8 3.2 13 #9 3.7 4 #10 3.5 21
In this sample, the correlation is -.63.

How does experimental research differ importantly from correlational research methods?
how does experimental research differ importantly from correlational research methods Correlational Research are predictions and are mostly based on statistics. Whereas Experimental Research is based on experiment and explaination.
Correlational research is useful because it can?
i
What are the two methods of research in psychology?
Experimental and correlational
Correlational research is most useful for purposes of?
Prediction.
This is the type of research that describes the strength and direction of relationships between variables?
Correlational
What are the weaknesses of using correlational research?
Causation cannot be determined... You cannot be certain which is the cause and which is the effect, as the correlational data is only supporting the idea that they are both occurring together.
What type of research study can suggest likely associations but not cause-and-effect relationships?
correlational
A major disadvantage of correlational research is that?
It cannot be used to demonstrate cause and effect relationships.
Classification of research?
Research is classified based on purpose and by method. A research can be done for the purpose of either developing a theory or making a decision. It can be done by historical or correlational research.
What are the advantages of the correlational method?
The advantage of the correlational research method is the ability to prove a positive or negative correlation between two subjects . The disadvantage of this is the unclear interpreation of cause and affect. moletsane
Which research method assesses how well one variable predicts another without specifying a cause and effect relationship between the variables?
Correlational research
What are the three basic research designs?
Three basic research designs are experimental, correlational, and quasi-experimental.Experimental designs have random assignment to conditions. Correlational designs define the relationship between two measured values. Quasi-experimental designs have participants grouped on a variable that isn't manipulated.
