Question

What is the difference between the percent change and percent error formulas?

1) The percent change formula divides by the original amount, while the percent error formula divides by the actual amount.
2) The percent change formula divides by the actual amount, while the percent error formula divides by the original amount.
3) The percent change formula multiplies by the original amount, while the percent error formula multiplies by the actual amount.
4) The percent change formula multiplies by the actual amount, while the percent error formula multiplies by the original amount.

Answer 1

The percent change formula divides by the original amount, while the percent error formula divides by the actual amount.

Step-by-step explanation:

The difference between the percent change and percent error formulas is that the percent change formula divides by the original amount, while the percent error formula divides by the actual amount.

For example, the percent change formula calculates the percentage increase or decrease from the original value, by dividing the change in quantity by the original amount.

On the other hand, the percent error formula calculates the percentage difference between the experimental value and the accepted value, by dividing the difference by the accepted value.
