Answer.
The given scatterplot represents the relationship between practice and accuracy in playing a piano. Here, the independent variable is plotted on the x-axis and it is the amount of time ( in hours) spent in practising. The dependent variable ( as shown on the y-axis) is measured as the number of piano notes inaccurately played with time.
The graph shows a linear negative correlation between the independent and the dependent variables. This means that the decrease in the number of inaccurate notes played by the participants occurs alongside a simultaneous increase in the amount of practice time.
