Three-dimensional graphs are useful for visualizing linear regression. Below are two examples of graphs that I prepared to be displayed during lectures in a statistics course. The first example is a visualization of multiple regression.

A student of Economic Analysis, Jan, volunteered when I asked if anyone could tell Pepsi from Coca-Cola by taste. So, we decided to conduct a test with the whole class during the statistics lecture.

Tomorrow, as part of the Baltic Science Festival, we will once again conduct statistics classes for primary school students entitled “How to weigh a dog using a ruler”. Among the instructors we will have students of Economic Analytics at the Faculty of Management and Economics of Gdańsk Tech Great thanks to Przemysław Biecek for the materials!
