2 апр. 2023 г. · The hypothesis test lets us decide whether the value of the population correlation coefficient ρ is "close to zero" or "significantly different from zero".

13 дек. 2023 г. · The correlation coefficient, r, tells us about the strength and direction of the linear relationship between X1 and X2.

The Pearson correlation coefficient is used to measure the strength of a linear association between two variables.

12 мар. 2023 г. · The t-test is a statistical test for the correlation coefficient. It can be used when x and y are linearly related, the variables are random variables.

The correlation coefficient is the specific measure that quantifies the strength of the linear relationship between two variables in a correlation analysis.

The correlation coefficient is a statistical measure of the strength of a linear relationship between two variables. Its values can range from -1 to 1.

In this section, we learn how to conduct a hypothesis test for the population correlation coefficient (the greek letter "rho").
