In a survey of road accidents in Durban, South Africa, it was discovered that during the rainy season of 2006, eighty percent (80%) of car accidents involved men. Example 2 shows how similar calculations can be done. To illustrate this, imagine if the government increases taxes from 4% to 6%, that’s a 50 percent tax increase but a 2-percentage point tax increase. However, using one in place of the other can give the information being conveyed a completely different meaning. In texts and even in presentations, percentage and percentage points are often interchanged. In the example above, we can say that there was an increase in the success rate by 25 pp.ĭistinguishing Between Percentage and Percentage Point Step 3: Add your unit (percentage points): The difference in exam success rates between 20 is 25 percentage points. Step 2: Subtract the smaller percentage from the larger percentageĬhange in exam success rates = 65 - 40 = 25 Step 1: Highlight the percentages you need to compare. To calculate the percentage point, follow these steps: What is the change in the examination success rates between 20? In 2019, in the same school, sixty-five percent (65%) of students passed the same examinations, and in 2020, 69% were successful. Andrew’s Catholic Boys’ School, forty percent (40%) of students passed the A levels mock examinations that were administered by the state. Some examples to illustrate the percentage point calculations are given below: Example 1
Many statisticians and analysts prefer the use of percentage points to percentages when comparing amounts. Percentage point is used in a wide range of applications, ranging from probability studies to fault/ risk analysis to descriptive statistics to investment predictions.

Percentage point, on the other hand, is a unit of measurement that represents the difference between two percentages.Percentage point is often represented as "pp" or "p.p." In other books, it is written in full as “percentage points” or “percent points” to avoid confusing it with “pages.” Understanding Percentage Point Percentages are similar to ratios, but they're expressed as a fraction of 100. Ratios express the quantitative relationship between values by showing how many times one is contained in another. Some of these metrics include ratios, percentages, and percentage points. In mathematics, there are various metrics used to simplify or explain events or outcomes - especially those that involve changes or comparison.
