Question

a teacher put all her students quiz scores up on the representation below. what was the most common score interval? quiz scores frequency (number of students) points: 40-49, 50-59, 60-69, 70-79, 80-89, 90-99

Explanation:

Step1: Analyze the bar graph

We look at the bar graph where the x - axis represents the frequency (number of students) and the y - axis represents the quiz score intervals.

Step2: Compare the heights of the bars

We compare the heights of each bar corresponding to different score intervals (40 - 49, 50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 99). The bar for the score interval 60 - 69 is the tallest among all the bars, which means it has the highest frequency (number of students). So the most common score interval is 60 - 69.

Answer:

60 - 69
