Introducing Measures of relation
With the help of correlation analysis we can describe the strength of a linear relationship between two variables.
Roughly, we can differentiate the following correlations:
During an evaluation of teachers it is found, that students are more satisfied, when teachers are better qualified, we speak about a correlation between these variables.
If you find out that there is no connection between the measured size of a persons head and his intelligence, we speak of independent variables.
If you find out that a good grade in a mathematics exam usually goes along with a lower grade in a vocabulary quiz, we talk about opposing variables.
