The following data were collected for two related variables x and y.
A scatterplot indicates a non-linear association. The data is linearised using a logx transformation and a least squares line is then fitted. The equation of this line isclosest to:
Is the variable birth weight the independent variable (IV) or the dependent variable (DV)?
(Write your answer as IV or DV only)
A 1/y transformation is used to linearise a scatterplot.The equation of a least squares line fitted to this data is:
1/y = 0.14 + 0.045x
This regression line predicts that, when x = 6, y is closest to:
