The histogram in the dashboard show how writing scores are spread among students. Most students got marks in the average range, while only few students got very low or very high marks.
The scatter plot shows a strong positive connection between reading marks and writing marks. Students who got high marks in reading also got high marks in writing most of the time.
The regression graph clearly shows an upward line between reading marks and writing marks. This means students with high reading scores usually got high writing scores too. The regression line also proves the positive relationship found in the analysis.
