To calculate the average height of a group, you need to sum the heights of all individuals in the group and then divide that total by the number of individuals.
Here's a breakdown of the process:
-
Measure Each Individual's Height: Record the height of each person in the group. Make sure all heights are measured in the same unit (e.g., inches, centimeters, feet).
-
Sum the Heights: Add up all the individual heights to get the total height of the group.
-
Count the Number of Individuals: Determine the total number of people in the group.
-
Divide the Total Height by the Number of Individuals: Divide the total height (calculated in step 2) by the number of individuals (calculated in step 3). The result is the average height of the group.
Formula:
Average Height = (Sum of All Heights) / (Number of Individuals)
Example:
Let's say you have a group of five people with the following heights:
- Person 1: 5'8" (68 inches)
- Person 2: 6'0" (72 inches)
- Person 3: 5'6" (66 inches)
- Person 4: 5'10" (70 inches)
- Person 5: 6'2" (74 inches)
- Sum of Heights: 68 + 72 + 66 + 70 + 74 = 350 inches
- Number of Individuals: 5
- Average Height: 350 / 5 = 70 inches
Therefore, the average height of the group is 70 inches (which is 5'10").
Important Considerations:
- Units: Ensure all heights are measured in the same unit before performing the calculations. Convert if necessary.
- Accuracy: The accuracy of the average height depends on the accuracy of the individual height measurements.
