1 : harmonious relation of parts to each other or to the whole : balance, symmetry. 2a : proper or equal share each did her proportion of the work. b : quota, percentage. 3 : the relation of one part to another or to the whole with respect to magnitude, quantity, or degree : ratio.

How do you do proportions in statistics?

p′ = x / n where x represents the number of successes and n represents the sample size. The variable p′ is the sample proportion and serves as the point estimate for the true population proportion. The variable p′ has a binomial distribution that can be approximated with the normal distribution shown here.

What is a proportion percentage?

A percent proportion is an equation where a percent is equal to an equivalent ratio. For example, 60%=60100 60% = 60 100 and we can simplify 60100=35 60 100 = 3 5 . Since the equation 60100=35 60 100 = 3 5 shows a percent equal to an equivalent ratio, we call it a percent proportion.
