An assumption of linear regression states that for each value of X, there is a group of Y values that are statistically __________________ and normally distributed about the regression line. ________________________________________

.	For an inverse relationship between two variables, the sign of the correlation coefficient is __________________.

The standard error of the estimate measures the scatter or dispersion of the observed values around a __________________________________________________________

Answer 1

1)The proportion of explained variation is called the Coefficient of determination

2) An assumption of linear regression states that for each value of X, there is a group of Y values that are statistically independent and normally distributed about the regression line.

3) For an inverse relationship between two variables, the sign of the correlation coefficient is negative

4) The standard error of the estimate measures the scatter or dispersion of the observed values around a estimated (predicted) value
