Question: If the correlation coefficient is negative, this means the calculation was done wrong the regression line can be used for prediction the test statistic, t

If the correlation coefficient is negative, this means

  • the calculation was done wrong
  • the regression line can be used for prediction
  • the test statistic, t can not be calculated
  • the slope of the regression line is negative
  • there is a strong correlation between the variables
  • there is no correlation between the variables
