Question

The proportion of explained variation is called the _______________.

If there is absolutely no relationship between two variables, Pearson's r will equal _____.

The _______________ principle is applied when calculating the regression coefficients.

The _________________ of _________________ is expressed as a percent, its value is between 0 and 100%.

In plotting paired data in a scatter diagram, the independent variable is scaled on the __________________.

Answer 1

Solution:

The proportion of explained variation is called the r-squared value.

If there is absolutely no relationship between two variables, Pearson's r will equal 0 (Zero)

The Least Squared principle is applied when calculating the regression coefficients.

The degree of linear relationship is expressed as a percent, its value is between 0 and 100%.

In plotting paired data in a scatter diagram, the independent variable is scaled on the horizontal axis (i.e. X-axis)

Best Luck !
