# Sample Proportions

In this post, we understand the concept of the sample proportion \hat{p} as a random variable whose value varies between samples, and the formulas for the mean p and standard deviation \sqrt{p(1-p)/n} of the sample proportion \hat{p} . This syllabus dot point is a part of the VCE Maths Methods topic Probability and Statistics.
