Activity D

Collection of data involving two independent measures and analysis using a test of correlation.

Correlation is a method of data analysis which is a measure of how strongly two variables are related to each other.  

You will need a clear correlational hypothesis and null hypothesis.   It is important that your hypothesis is correlational and not a prediction of difference.

Note that you are looking for a relationship between two independent variables and there is no dependent variable.

You will need to carry out both descriptive and inferential statistics for this activity.  More on statistics.

You are allowed to use software to calculate your statistics.  Some statistical tests can be found here.

You will need to know about the difference between positive, negative and zero correlation, correlation coefficient and limitations of correlation.  More on correlation.
