how do you find the mean in math
To find the mean in math, you add up all the numbers in a set of data and divide by the total number of values in the set.
Formula: Mean = (Sum of all values) ÷ (Number of values)
Example: Find the mean of the following set of data: 10, 12, 15, 18, 20
Solution:
1. Add up all values: 10 + 12 + 15 + 18 + 20 = 75
2. Divide by the number of values: 75 ÷ 5 = 15
3. The mean of the set is 15.
how do you find the range
To find the range of a set of data in math, subtract the smallest value from the largest value in the set.
Formula: Range = Largest value - Smallest value
Example: Find the range of the following set of data: 10, 12, 15, 18, 20
Solution:
1. Find the smallest value: 10
2. Find the largest value: 20
3. Subtract the smallest value from the largest value: 20 - 10 = 10
4. The range of the set is 10.
To find the mean in math, follow these step-by-step instructions:
1. Collect the data: Gather the set of numbers for which you want to find the mean. For example, let's say you have the following set of numbers: 5, 8, 12, 6, 10.
2. Add up the numbers: Sum all the numbers in the set. In our example, 5 + 8 + 12 + 6 + 10 = 41.
3. Count the numbers: Determine how many numbers are in the set. In our example, there are 5 numbers in total.
4. Calculate the mean: Divide the sum of the numbers by the count of numbers. In our example, 41 ÷ 5 = 8.2.
5. Interpret the mean: The mean is the average value of the set. In our example, the mean of the set of numbers is 8.2.
