Represent the data in each notice in a suitable graph.

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.

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.

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.
