Abstract:
In this paper we present an exploratory study intended to characterise University students' understanding of correlation and regression. We analyse the solutions to two problems from an intentional sample of 193 students who had previously received a course of descriptive statistics at the University. We study the student's procedures and discuss their difficulties and errors concerning the centre of gravity in the scatter plot, regression lines, correlation coefficient, type of relation between the variables and prediction.
