Every year the state department of education gathers statistical information from all schools to award a letter grade showing the school’s academic performance. Each school is given a rating based on the median of the grades. A school principal used a bar graph to send his report. He assigned the horizontal axis to the student’s name and the vertical axis to the grades. Why was this a mistake? Explain what you would have done to send the results in a proper manner and complete.

Respuesta :

A school principal used a bar graph to send his report. He assigned the horizontal axis to the student’s name and the vertical axis to the grades. If the x-axis (the horizontal axis) is the students name and the y-axis (the vertical axis) are the grades. There has to be multiple bar-graphs per student. Otherwise the data would be incomplete.

Answer:

Because there is too much info that the principal put in his bar graph and it would be difficult to read. I would have assigned the grade to the horizontal axis and the number of students who made that grade to the vertical axis, then it would have been easier to read.
