4. Indicate the ability of something or the probability of having certain properties, such as: oil yield = oil quality/total physical quality × 100%, germination rate = germination number/total number of seeds × 100%.
Extended data
Percentages can unify the basis of two survey results with different capacities and facilitate comparison. When using, we should first standardize the capacity of the category. If the sum of all data is 100 and the proportion of each category remains the same, the sum of all percentages should be 100.
Secondly, percentages are usually used for real numbers with cardinality greater than 100. When the cardinality is less than 100, it should be expressed in actual quantity in principle. Because of its intuitive display and simple calculation, percentage method has become the most basic and commonly used method to display and compare data distribution patterns in social investigation and communication research.
