Within the realm of numerical evaluation, figuring out the % distinction between two numbers is a elementary talent that finds purposes in varied fields starting from statistics to engineering. This text goals to offer a complete and easy-to-understand information to calculating the % distinction, equipping readers with the required information to sort out this important job.
The % distinction, often known as relative distinction or relative error, quantifies the magnitude of the distinction between two numbers in relation to their common worth. It’s expressed as a share and is calculated by dividing absolutely the distinction between the 2 numbers by their common after which multiplying by 100.
With this conceptual basis in place, let’s delve into the detailed steps concerned in calculating the % distinction, guaranteeing a radical understanding of the method.
Calculating the % Distinction Between Two Numbers
To calculate the % distinction, comply with these 8 necessary steps:
- Discover absolutely the distinction.
- Discover the common of the 2 numbers.
- Divide absolutely the distinction by the common.
- Multiply the consequence by 100.
- Interpret the % distinction.
- Think about the context.
- Use a calculator or spreadsheet.
- Examine your work.
By following these steps, you’ll be able to precisely calculate the % distinction between two numbers and acquire beneficial insights into the magnitude of their distinction.
Discover absolutely the distinction.
Step one in calculating the % distinction between two numbers is to search out their absolute distinction. Absolutely the distinction is just the distinction between the 2 numbers, with out regard to their indicators. To search out absolutely the distinction, comply with these steps:
- Subtract the smaller quantity from the bigger quantity.
- If the result’s damaging, multiply it by -1 to make it optimistic.
For instance, if the 2 numbers are 10 and 15, absolutely the distinction is:
15 – 10 = 5
If the 2 numbers are -5 and -10, absolutely the distinction is:
| -5 – (-10) | = |-5 + 10| = 5
Upon getting discovered absolutely the distinction, you’ll be able to proceed to the following step of calculating the % distinction.
Discover the common of the 2 numbers.
The following step in calculating the % distinction between two numbers is to search out their common. The common is just the sum of the 2 numbers divided by 2. To search out the common, comply with these steps:
-
Add the 2 numbers collectively.
This offers you the sum of the 2 numbers.
-
Divide the sum by 2.
This offers you the common of the 2 numbers.
For instance, if the 2 numbers are 10 and 15, the common is:
(10 + 15) / 2 = 25 / 2 = 12.5
If the 2 numbers are -5 and -10, the common is:
(-5 + (-10)) / 2 = -15 / 2 = -7.5
Upon getting discovered the common, you’ll be able to proceed to the following step of calculating the % distinction.
Divide absolutely the distinction by the common.
The following step in calculating the % distinction between two numbers is to divide absolutely the distinction by the common. This offers you a worth that represents the relative distinction between the 2 numbers. To divide absolutely the distinction by the common, comply with these steps:
-
Discover absolutely the distinction between the 2 numbers.
This is step one in calculating the % distinction.
-
Discover the common of the 2 numbers.
That is the second step in calculating the % distinction.
-
Divide absolutely the distinction by the common.
This offers you the relative distinction between the 2 numbers.
For instance, if the 2 numbers are 10 and 15, absolutely the distinction is 5 and the common is 12.5. To search out the relative distinction, we divide absolutely the distinction by the common:
5 / 12.5 = 0.4
If the 2 numbers are -5 and -10, absolutely the distinction is 5 and the common is -7.5. To search out the relative distinction, we divide absolutely the distinction by the common:
5 / (-7.5) = -0.67
Upon getting discovered the relative distinction, you’ll be able to proceed to the following step of calculating the % distinction.
Multiply the consequence by 100.
The ultimate step in calculating the % distinction between two numbers is to multiply the relative distinction by 100. This converts the relative distinction to a share. To multiply the relative distinction by 100, comply with these steps:
-
Discover the relative distinction between the 2 numbers.
That is the third step in calculating the % distinction.
-
Multiply the relative distinction by 100.
This converts the relative distinction to a share.
For instance, if the 2 numbers are 10 and 15, the relative distinction is 0.4. To search out the % distinction, we multiply the relative distinction by 100:
0.4 * 100 = 40%
Which means that the 2 numbers differ by 40%.
If the 2 numbers are -5 and -10, the relative distinction is -0.67. To search out the % distinction, we multiply the relative distinction by 100:
-0.67 * 100 = -67%
Which means that the 2 numbers differ by 67%.
Upon getting discovered the % distinction, you’ll be able to interpret the outcomes and draw conclusions.
Interpret the % distinction.
