What is a Statistical Proportion and it's importance?

In Statistics, some particular numerical ratios which connects some important variables or parameters associated with the given data or distribution are called statistical proportions. Comparison of multiple data is the main advantage of these proportions. In statistical data analysis various proportions has a wide applications. For example, at the time of comparing two different data, comparing the performance of a company with last year performance, comparing the quality of one set of products to the next set of products, etc if we compare a fixed proportion of each group of data, we can take many useful conclusions.
