Calculating the Percent Difference Between Two Numbers: An Elementary Guide


Calculating the Percent Difference Between Two Numbers: An Elementary Guide

Within the realm of numerical evaluation, figuring out the p.c distinction between two numbers is a basic ability that finds functions in varied fields starting from statistics to engineering. This text goals to supply a complete and easy-to-understand information to calculating the p.c distinction, equipping readers with the mandatory data to sort out this important job.

The p.c distinction, also referred to 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 p.c distinction, making certain a radical understanding of the method.

Calculating the % Distinction Between Two Numbers

To calculate the p.c distinction, comply with these 8 essential steps:

  • Discover absolutely the distinction.
  • Discover the typical of the 2 numbers.
  • Divide absolutely the distinction by the typical.
  • Multiply the end result by 100.
  • Interpret the p.c distinction.
  • Contemplate the context.
  • Use a calculator or spreadsheet.
  • Verify your work.

By following these steps, you may precisely calculate the p.c distinction between two numbers and acquire worthwhile insights into the magnitude of their distinction.

Discover absolutely the distinction.

Step one in calculating the p.c distinction between two numbers is to search out their absolute distinction. Absolutely the distinction is solely the distinction between the 2 numbers, with out regard to their indicators. To seek out absolutely the distinction, comply with these steps:

  1. Subtract the smaller quantity from the bigger quantity.
  2. If the result’s destructive, multiply it by -1 to make it constructive.

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

After you have discovered absolutely the distinction, you may proceed to the subsequent step of calculating the p.c distinction.

Discover the typical of the 2 numbers.

The subsequent step in calculating the p.c distinction between two numbers is to search out their common. The common is solely the sum of the 2 numbers divided by 2. To seek out the typical, comply with these steps:

  • Add the 2 numbers collectively.

    This provides you the sum of the 2 numbers.

  • Divide the sum by 2.

    This provides you the typical of the 2 numbers.

For instance, if the 2 numbers are 10 and 15, the typical is:

(10 + 15) / 2 = 25 / 2 = 12.5

If the 2 numbers are -5 and -10, the typical is:

(-5 + (-10)) / 2 = -15 / 2 = -7.5

After you have discovered the typical, you may proceed to the subsequent step of calculating the p.c distinction.

Divide absolutely the distinction by the typical.

The subsequent step in calculating the p.c distinction between two numbers is to divide absolutely the distinction by the typical. This provides you a price that represents the relative distinction between the 2 numbers. To divide absolutely the distinction by the typical, comply with these steps:

  • Discover absolutely the distinction between the 2 numbers.

    This is step one in calculating the p.c distinction.

  • Discover the typical of the 2 numbers.

    That is the second step in calculating the p.c distinction.

  • Divide absolutely the distinction by the typical.

    This provides 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 typical is 12.5. To seek out the relative distinction, we divide absolutely the distinction by the typical:

5 / 12.5 = 0.4

If the 2 numbers are -5 and -10, absolutely the distinction is 5 and the typical is -7.5. To seek out the relative distinction, we divide absolutely the distinction by the typical:

5 / (-7.5) = -0.67

After you have discovered the relative distinction, you may proceed to the subsequent step of calculating the p.c distinction.

Multiply the end result by 100.

The ultimate step in calculating the p.c 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 p.c 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 seek out the p.c 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 seek out the p.c distinction, we multiply the relative distinction by 100:

-0.67 * 100 = -67%

Which means that the 2 numbers differ by 67%.

After you have discovered the p.c distinction, you may interpret the outcomes and draw conclusions.

Interpret the p.c distinction.
