Cumulative Frequency Practice Problems
Some practice problems on cumulative frequeny are,
Problem 1: Determine the cumulative frequency of the results of a group of students’ physics tests are shown in the table below:
Score | 60 | 70 | 80 | 90 | 100 |
---|---|---|---|---|---|
Frequency | 4 | 8 | 10 | 6 | 2 |
Problem 2: Given a population’s ages and their cumulative frequency distribution:
Age | 20-29 | 30-39 | 40-49 | 50-59 | 60-69 |
---|---|---|---|---|---|
Cumulative Frequency | 15 | 30 | 45 | 60 | 75 |
Calculate the total number of individuals in the population.
Problem 3: The hours that each student in the group studied are shown in the table below. Determine the frequency cumulatively.
Hours | 1-5 | 6-10 | 11-15 | 16-20 | 21-25 |
---|---|---|---|---|---|
Frequency | 6 | 8 | 10 | 5 | 3 |
Problem 4: The following shows the weight of a group of people’s cumulative frequency distribution. Calculate the weighted median.
Weight | 50-59 | 60-69 | 70-79 | 80-89 | 90-99 |
---|---|---|---|---|---|
Cumulative Frequency | 8 | 15 | 23 | 30 | 36 |
Problem 5: A group of students timed how long it took them to finish an exam in minutes. Here is the cumulative frequency:
Time(min) | 0-5 | 6-10 | 11-15 | 16-20 | 21-25 |
---|---|---|---|---|---|
Cumulative Frequency | 10 | 22 | 30 | 40 | 45 |
Determine how many students participated in the quiz overall.
Cumulative Frequency
Cumulative Frequency: In statistics, cumulative frequency is defined as the sum of frequencies distributed across various class intervals. This involves organizing the data and their totals into a table where the frequencies are allocated according to each class interval.
In this article, we will cover a thorough explanation of cumulative frequency, cumulative frequency curve, formula, and a few examples based on it for better understanding.
