If the coefficient of correlation r = 0, then there is no linear relationship whatsoever between the dependent variable y and the independent variable x.
举一反三
- An inverse relationship between an independent variable x and a dependent variably y means that as x increases, y decreases, and vice versa.
- If you were to run an experiment on the effects of temperatures on aggressive behavior, aggressive behavior would be the ________. A: hypothesis B: dependent variable. C: independent variable D: correlation coefficient
- In $G(x)=a_0+a_1 x_ +a_2 x^2+..+a_n x^n+⋯$, generating function is concerned of: A: Variable x B: Target function G(x) C: Coefficient ai
- The Pearson coefficient of correlation r equals 1 when there is/are no:
- This equation holds(成立), no matter what the independent variable(自变量) be.
