Use the slider to choose the number of points you want.
You can drag any of the points around the screen.
- Try to guess the approximate value of the product moment correlation coefficient before revealing it.
- Choose a target value for the correlation coefficient and move the points around to try to achieve this.
- Do you find it easier to guess the correlation coefficient if there are more points?
Try to guess the result of the hypothesis test before clicking the checkbox to show the result of the test. When you have selected "Show hypothesis test" you can vary the significance level of the test, and whether it is one-tailed or two-tailed.
