Statistics Exam - Correlation and Linear Regression
This practice exam covers correlation and linear regression - the Correlation calculator, the Linear Regression calculator and the Multiple Linear Regression calculator.
The questions ask which of those tools fits a situation, what each one assumes, how to read the output it prints, and what number it produces. Every solution links the calculator that solves it, so you can reproduce each answer yourself.
Ready for more? The Correlation & Regression Inference exam covers hypothesis testing, confidence intervals and multicollinearity/VIF.

Question types:
- Multiple choice - Choose the correct answer.
- Results - Fill in the results. You should round the final answer to at least 3 decimal places.
Please don't round the results at every step; if you do so, the final result will not be correct.
For example, if the result is 33.56789, you may enter: 33.568, or 33.56789, but you can't enter 33.567 without rounding, or round it to 2 decimal places as 33.57.
If the answer is smaller than 1 (a probability or a p-value), give at least 3 significant digits: for 0.041889 you may enter 0.0419 or 0.041889, but not 0.042.
