WebMar 26, 2024 · The p hat is a symbol which stands for sample proportion. In equations, it is represented as a lower-case p with a small caret above it. To understand what the p hat symbol represents and how it is used, the difference between a population and a sample must first be understood. In the study of statistics, the word “population” refers to the ... WebIn statistics and probability theory the Greek small letter mu μ is used to denote a population mean or expected value. For example, the expected value of the mean under the null hypothesis would be denoted by μ 0 while the expected value of the alternative hypothesis will be denoted by μ 1. The observed value of mu will be simply μ.
WebThe population means is the mean or average of all values in the given population. It is calculated by the sum of all values in the population, denoted by the summation of X divided by the number of population values denoted by N. It arrives by summing up all the observations in the group and dividing the summation by the number of observations.
