Data indicate that people who prefer to watch televised news programs are less knowledgeable than those who read newspapers and newsmagazines." this statement is an example of a(n):
a. causality.
b. independent variable.
c. correlation.
d. law.

The answer is c. correlation.

Explanation:

Correlation is the relationship between two variables, which may be causal or not. In the example, there is no way to be sure that reading the papers actually makes people more knowledgeable, thus it can't be determined as causality.

Correlations, especially causal, are useful to define future patterns in an investigation.

c. correlation

Explanation:

Correlation means there is an association between two variables , which means there is observable relations between the two.

Correlation can happen in three ways a positive , negative and zero correlation

A positive correlation occurs when both variables increase and decrease all at once , so when one variable decreases this other variable also decreases. For example as the taller the person the heavier they get so height and weight increase at the same time.

A negative correlation occurs when there is an opposite relationship such that when one variable decreases the other one increases. When you climb the mountain the temperature decreases , hence an increase in height (mountain climb)leads to a decrease in temperature.

A zero correlation means no association exist.

In this case above we see a correlation between watching TV and being knowledgeable , the more people watch TV news the less knowledgeable they become which means there is a negative correlation, the more you watch TV news the lesser the knowledge you will have.
