Requirements for hypothesis testing
WebThis process, called hypothesis testing, consists of four steps. State the hypotheses. This involves stating the null and alternative hypotheses. The hypotheses are stated in such a way that they are mutually exclusive. That is, if one is true, the other must be false. Formulate an analysis plan. After developing your initial research hypothesis (the prediction that you want to investigate), it is important to restate it as a null (Ho) and alternate (Ha) hypothesis so that you can test it mathematically. The alternate hypothesis is usually your initial hypothesis that predicts a relationship between variables. The null … See more For a statistical test to be valid, it is important to perform samplingand collect data in a way that is designed to test your hypothesis. If your data are not … See more There are a variety of statistical tests available, but they are all based on the comparison of within-group variance (how spread out the data is within a category) … See more Based on the outcome of your statistical test, you will have to decide whether to reject or fail to reject your null hypothesis.

Null hypothesis (H 0): The population mean equals a hypothesized value (µ = µ 0).; Alternative hypothesis (H A): The population mean DOES NOT equal a hypothesized value (µ ≠ µ 0).; When the p-value is less or equal to your significance level (e.g., 0.05), reject the null hypothesis. The difference between your sample mean and …
WebThe critical value for conducting the left-tailed test H0 : μ = 3 versus HA : μ < 3 is the t -value, denoted -t( α, n - 1) , such that the probability to the left of it is α. It can be shown using either statistical software or a t -table that the critical value -t0.05,14 is -1.7613. That is, we would reject the null hypothesis H0 : μ = 3 ...
WebAug 5, 2024 · Student’s t-tests are commonly used in inferential statistics for testing a hypothesis on the basis of a difference between sample means.
