Input Data :
`V_1` = 100
`V_2` = 250
Find the percent difference between two values.
Percentage difference calculator uses two values, $Y_1$ and $Y_2$, either both positive or both negative real numbers,
and calculate the percent difference between these numbers. It is an online mathematical tool requires two real numbers and finds the percentage difference between two real numbers
in order to determine how close they are, relative to average (arithmetic mean) of these numbers.
It is necessary to follow the next steps:
The percent difference between two real numbers is percent that determines how close they are relative to average of these numbers. There are other formulas for the percent difference. For instance, the percent difference between two numbers $Y_1$ and $Y_2$ can also be calculated in the following ways:
A percent difference between two numbers $Y_1$ and $Y_2$ is the absolute value of the difference between two numbers, divided by the average of these numbers, and multiplied by $100\%$. This means,
The percent difference is useful in comparing number values that are relatively close to one another. In some experiments, results are compared, in order to derive prediction. This comparison uses a different type of analysis, percent difference or percent error. When we compare two experimental quantities, $Y_1$ and $Y_2$, neither of which can be considered the correct value, instead of these values we will use the percent difference.
Pracrice Problem 1: Find the percentage difference between $3$ and $17$.
Pracrice Problem 2: Two groups of mathematicians are participating in the mathematical congress. A group of geometers has $235$ people, while the group of statisticians has $218$ people. Find the percent difference in the number of these groups.
The percentage difference calculator, formula, example calculation (work with steps), real world problems and practice problems would be very useful for grade school students (K-12 education) to learn how to find how much percent difference between two numbers or quantities. This concept can be useful in manufacturing, economics, statistics, etc.
