Ask the master what is the difference between rising by 1 and rising by 1 percentage point

This is the difference between written and spoken language, both of which refer to an increase of 1% from the original to 101%. Meet Lu Shuxiang.

The official website shall prevail.

1% is a percentage, and 1 percentage point is a percentile.

For example, the illiteracy rate was 10 per cent last year, and if it becomes 11 per cent this year, it will increase by 1 percentage point. Of course, it can be said that there has been an increase of 1%, but then there is a difference in whether it will increase from 10% to 11% relative to the total population, or 1% relative to the 10% illiterate population, and if it is the latter, it should be this year.

So, in this case, when the value described is itself in percentages, it is usually said that "one percentage point has increased". In other words, "1 percentage point" is generally used to describe the increase or decrease in the percentage value itself.

To put it simply, a percentage point is the percentage of the same number that increases by two other numbers relative to that number, and the difference between them is the percentage point.

percentages" and "percentiles".

A percentage is a fraction with a hundred as the denominator, which is represented by " " in mathematics and "how many percent" is generally written in essays. A percentage, unlike a multiple, can represent both an increase in quantity and a decrease in quantity.

When using percentages, you should also pay attention to the precision of the concept. For example, "20 more than in the past", that is, it used to be 100, and now it is "120"; "20 lower than in the past", i.e. 100 in the past, 80 now; "Reduced to 20", i.e. 100, now "20".

When using percentages, it should also be noted that some numbers can only reach 100% at most, such as product qualification rate, seed germination rate, etc.; Some percentages can only be less than 100, such as grain flour yield; Some percentages can exceed 100, such as the completion of product yield plans.

Extended Material: Common Fallacies About Percentages:

1. Percentages often represent a proportional relationship, but percentages can sometimes exceed 100%.

2. The nutrient reference value in the nutrient facts table on the food packaging box does not indicate the percentage of the substance in the food, but the proportion of the amount of the substance in the food to the per capita normal daily intake, which also explains why the sum of the percentages in the nutrition facts table is often not equal to 100%.

For example, assuming that a normal person should consume an average of 60 grams of fat per day, then a food containing 6 grams of fat per 100 grams should be marked with 10% instead of 6% in the nutrition facts list.

3. The survival rate, germination rate, attendance rate, oil yield, score rate, etc. indicate that the percentage of individuals in the total will not exceed 100% (maximum 100%)

4. Percentages have different meanings in different situations. For example, the sentence "'The probability of precipitation tonight is 20%" indicates that there is a 20% probability of rain (snow) tonight, but it does not mean that it will rain (snow) 20% of the time tonight.
