Here's how to represent the data from each notice in a suitable graph: Step 1: Representing "Walkathon participants by grade" This data compares two categories (Boys and Girls) across different grades. A double bar graph is suitable for this. The horizontal axis (x-axis) would represent the Grades* (Grade 8, Grade 9, Grade 10, Grade 11, Grade 12). The vertical axis (y-axis) would represent the Number of Participants*. For each grade, there would be two adjacent bars: one for boys and one for girls, using different colors or patterns to distinguish them. Step 2: Representing "Times taken by the participants to complete the walkathon" This data shows the frequency of participants within specific time intervals. A histogram is suitable for this type of continuous, grouped data. The horizontal axis (x-axis) would represent the Time taken (minutes)*, with intervals like 0-30, 31-60, 61-90, and 91-120. The vertical axis (y-axis) would represent the Number of Participants* (frequency). The bars in a histogram touch each other to indicate the continuous nature of the data. Step 3: Representing "Walkathon prize winners by grade" This data shows the number of prize winners for each distinct grade. A bar graph (or column graph) is suitable for this. The horizontal axis (x-axis) would represent the Grades* (Grade 8, Grade 9, Grade 10, Grade 11). The vertical axis (y-axis) would represent the Number of Prize Winners*. Each bar would correspond to a grade, showing the count of prize winners for that grade. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
