Mastering Histogram Analysis and Median Calculation

Mr. Maisonette explains how to interpret a histogram displaying test scores for a class. He guides viewers through identifying the number of students in various score ranges, calculating the total number of students, and determining how many scored below a B. The video also covers finding the median score range using the histogram data.

How many students scored between 0 and 59 percent?

• 2 students

• 7 students

• 3 students

• 4 students

How many students scored between 90 and 100 percent?

• 5 students

• 4 students

• 3 students

• 2 students

How many students scored between 80 and 89 percent?

• 6 students

• 8 students

• 7 students

• 5 students

What is the total number of students represented in the histogram?

• 17 students

• 21 students

• 15 students

• 19 students

What is the correct way to calculate the total number of students from the histogram?

• Average the scores of all ranges

• Add the highest and lowest scores

• Multiply the number of ranges by students in one range

• Sum the number of students in each range

How many students earned a grade lower than a B?

• 11 students

• 9 students

• 13 students

• 7 students

Which score range is considered for a grade of B?

• 80 to 89%

• 70 to 79%

• 90 to 100%

• 60 to 69%

In which percentage range does the median score fall?

• 80 to 89%

• 60 to 69%

• 70 to 79%

• 90 to 100%

How is the median position calculated in a set of 19 numbers?

• 19 * 2

• (19 - 1) / 2

• 19 / 2

• (19 + 1) / 2

What is the first step in determining the median score range in a histogram?

• Count the number of ranges

• Determine the position of the median

• Calculate the total number of students

• Identify the highest score
