Example of a Strong Negative Correlation A strong negative correlation graph is where the line touches or is very close to every data point, and the line has a negative slope. Example of a Weak Negative CorrelationLesson Summary Register to view this lesson Are you a student or a teacher?
A personnel department plots salary against the results of a motivation survey. The result is a weak negative correlation. A second Scatter Diagram, plotting time in company against motivation, gives a higher correlation. A motivation program is targeted accordingly and results in a steady increase ...

Instead of undertaking the difficult (and maybe impossible) task of establishing causality, most scientific research focuses on the strength of correlations. Correlations can be positive or negative, weak or strong. The statistical correlation coefficient, which ranges from -1 to 1, shows the streng...

Correlation is usually defined as a measure of the linear relationship between two quantitative variables (e.g., height and weight). Often a slightly looser definition is used, whereby correlation simply means that there is some type of relationship betw

Conscious bias, or explicit bias, involves known attitudes about certain groups of people. In contrast, unconscious bias involves attitudes about certain groups of people that are outside of one’s own awareness. Unconscious bias can be more difficult to recognize than conscious bias, and may lead...
A correlation is considered strong if the correlation coefficient has a value close to +1 (positive correlation) or -1 (negative correlation). A coefficient that is close to zero indicates that there is only a weak relationship between the two variables. ...
and the price of oil has generally trended upward over the same period. This is a positive correlation, but the two factors almost certainly have no meaningful relationship. That both the population of Internet users and the price of oil have increased is explainable by a third...
