What is the connection between a scatter plot and a calculation of correlation? (Select all that apply.)
 
  a. Constructing a scatter plot allows the researcher to visualize in advance whether a calculation of linear correlation is likely to reveal a relationship between the variables.
  b. Constructing a scatter plot produces a correlation coefficient, as does calculating correlation.
  c. A calculation of correlation should be performed before constructing a scatter plot, because the calculation is more scientific.
  d. The scatter plot provides a visual representation of the connection between two variables; a correlational calculation provides a quantification of the connection between the same variables.
  e. Just like calculation of correlation, constructing a scatter plot provides a way to quantify explained variance.
