The formula to calculate the Difference in Proportions is:
\[ D = P1 - P2 \]
Where:
A Difference in Proportions is a statistical tool used to compare the proportions or percentages of a specific characteristic between two or more groups. It is often used in hypothesis testing to determine if there is a significant difference between the groups. For example, it can be used to compare the proportion of males and females who prefer a particular product or the proportion of people in different age groups who vote for a particular candidate. The difference is calculated by subtracting the proportion in one group from the proportion in another group.
Let's assume the following values:
Using the formula to calculate the Difference in Proportions:
\[ D = 0.6 - 0.4 = 0.2 \]
The Difference in Proportions (D) is 0.2.
