Math Problem Statement
In your own words give 10 example of Your are going to collect/gather data (age, height, or weight) then organize those data by making a frequency distribution table and compute for the mean, median, mode and standard deviation
Solution
Certainly! Here are 10 examples of scenarios where you might gather data on age, height, or weight, organize it into a frequency distribution table, and compute key statistics like mean, median, mode, and standard deviation.
1. Classroom Heights
- Measure the height of each student in a classroom, group them by height ranges (e.g., 150-155 cm, 156-160 cm), and calculate the average, most common height, and variability in heights.
2. Sports Team Weights
- Record the weights of players on a sports team, categorize them by ranges (e.g., 60-65 kg, 66-70 kg), and analyze the central tendencies and variability.
3. Ages of Marathon Runners
- Gather the ages of runners in a local marathon, group them into age brackets (e.g., 18-25, 26-35), and compute the mean, median, mode, and standard deviation.
4. Family Member Ages
- Collect ages from several families, divide them into age categories (e.g., 0-10, 11-20), and calculate the central tendencies and age distribution spread.
5. Employee Heights in a Company
- Measure the height of employees in an organization, create ranges (e.g., 160-165 cm, 166-170 cm), and calculate statistical measures like mean height.
6. School Children's Weights
- Record weights of children in a school, organize them by ranges (e.g., 30-35 kg, 36-40 kg), and determine the average weight and variability.
7. Ages in a Community Center
- Collect ages of members at a community center, categorize them by ranges (e.g., 21-30, 31-40), and compute average and typical age.
8. Weight of Baggage on a Flight
- Collect the weights of passengers' checked baggage on a flight, create weight ranges (e.g., 10-15 kg, 16-20 kg), and calculate mean and variance of baggage weight.
9. Patient Heights in a Clinic
- Measure heights of patients visiting a clinic, organize by height categories (e.g., 150-155 cm, 156-160 cm), and analyze average and typical heights.
10. Ages of Conference Attendees
- Gather ages of people attending a conference, sort by age brackets (e.g., 25-30, 31-35), and determine mean, median, mode, and variation in ages.
