Respuesta :
We have to find which of the graph options is best to track the number of books that the students read each week and encourage them to increase them.
Option 1 (scatter plot): in this case, it is not useful in the sense that we can not compare the evolution in time of each student. We can only see the number of books per student for specific weeks.
Option 2 (time series): in this case, the attendance is not a variable of interest, so it is not suitable.
Option 3: A pie chart is only useful to compare proportions and percentages, and not track an evolution of a variable in time.
Option 4: This aggregation of the data in a Pareto only allows to compare the total number of books per week, but the evolution is not clear, as we sort the columns by the number of books instead of time.
Option 5: A time series with weeks in the x-axis and number of books in the y-axis let the teacher clearly see the evolution of books read in time. So this option is the most suitable.
Answer: Option 5 (time series)
