when the variance of x increases, what happens to r squared what would cause the r squared to decrease why does the variance of y decrease r squared what is the relationship between r squared and variance when the r squared value increases what is the difference which factor increases in the r squared change in t squared and r squared when the variance of x decreases, the value of r squared if the variance of y or the residuals increases, the value of r s squared decreases when the variance of the residuals increases then the value of the what is the relationship between residual variance and r squared when the variance of the residuals is increased, then the value of r squared increases how does r squared increase or decrease why does an increase in the r squared affect the r squared value of a regression? do residuals affect regression what is the affect of the variance on the residual what affects r/s squared what is the effect of residuals on the regression why does R squared increase if the variance of the residuals increases then the value of the r squared decreases quizlet
