Common fallacies
1 and percentage are often proportional, but sometimes the percentage can exceed 100%.
For example, 20 13, the growth rate of WeChat usage reached 203%.
2. The nutritional reference value in the nutrient composition table on the food packaging box does not refer to the percentage of the substance in the food, but refers to the ratio of the content of the substance in the food to the average daily intake, which also explains why the sum of the percentages in the nutrient composition table is often not equal to 100%.
For example, if a normal person consumes 60 grams of fat every day, then a food containing 6 grams of fat per 100 grams should be marked as 10% instead of 6% in the nutrient composition table.
3. The percentage of individuals such as survival rate, germination rate, attendance rate, oil yield and scoring rate in the total amount will not exceed 100% (maximum 100%).
4. Percentage has different meanings in different situations. For example, the phrase "the probability of rain tonight is 20%" means that the probability of rain (snow) tonight is 20%, but it doesn't mean that it will rain (snow) 20% of the time tonight.
