WebbIt is a crucial consideration in inferential statistics where you use a sample to estimate the properties of an entire population. For example, you gather a random sample of adult women in the United States, measure their heights, and obtain an average of 5’ 4” (1.63m). The sample mean (x̄) estimates the population mean (μ). WebbIn this article, you will learn about errors in hypothesis testing, their causes and how to balance them. Hypothesis Testing. Before we can talk about hypothesis testing and the errors that can occur, you should first know what a hypothesis is.
