Used to calculate relative changes or relative differences. For example, compare the sales growth rate between this year and last year, or compare the profit rate between different products. In statistical tables, percentages are usually expressed in the form of percent sign (%), which can compare the relationship between different data more intuitively. The percentage is calculated by multiplying the decimal or fraction by 100, and then adding the percent sign. For example, 0.25 can be expressed as 25%, and 5/2 can be expressed as 200%.
In a word, the application of percentage in statistical tables can help us to understand the data more intuitively, compare the relationships between different data and calculate the relative changes or differences. Percent is a mathematical symbol indicating proportion or ratio, which is widely used in our daily life, study and work. Percentages can be used to compare the proportion or quantity of different things or people, express the scale or degree of things, and calculate the relative changes or differences.

Percentage is also widely used in various fields.
For example, in the financial field, percentage is used to indicate the degree of change of stock price and the return on investment. In the medical field, percentage is used to indicate the incidence rate, cure rate and other indicators; In the field of social science, percentage is used to express the proportion of population, employment rate and other indicators. By using percentages, it is more convenient to compare and analyze, so as to better understand the relationship and changing trend between different things.
In a word, percentage is a very useful mathematical symbol, which is widely used in our daily life, study and work. By using percentages, we can understand the data more intuitively, compare the relationships between different data, and calculate the relative changes or differences. Percentages are widely used in various fields, which can help us better understand and analyze problems and make more informed decisions.
