Post by: Beezus on Mar 3, 2018
Although the correlation coefficient measures the strength of a linear relationship, it does not tell us about the mathematical relationship between the two variables.
  Indicate whether the statement is true or false

Q. 2

If the data points form a straight horizontal or vertical line, there is strong correlation.
  Indicate whether the statement is true or false

Q. 3

The closer the absolute value of r is to one, the better will be the predictions made using the equation of the line of best fit, provided the prediction is made for x values between the smallest value of x and the largest value of x in the observed data.
  Indicate whether the statement is true or false

Q. 4

When both variables from a bivariate set of data are quantitative, the appropriate measure of linear relationship is the coefficient of linear correlation.
  Indicate whether the statement is true or false

Q. 5

If two variables are not linearly correlated, then they are not related.
  Indicate whether the statement is true or false

Q. 6

If there is high positive linear correlation between two variables, then there is a strong relationship between the two variables.
  Indicate whether the statement is true or false
