We typically want to know if the slope coefficient, b 1, is statistically significant. To determine if b 1 is statistically significant, we can perform a t-test with the following test statistic: t = b 1 / se(b 1) where:

Nettet10. nov. 2024 · T-tests are hypothesis tests that assess the means of one or two groups. Hypothesis tests use sample data to infer properties of entire populations. To be able to use a t-test, you need to obtain a random sample from your target populations. Depending on the t-test and how you configure it, the test can determine whether:
NettetA One Sample T-Test is a statistical test used to evaluate the null hypothesis that the mean m of a sample dataset of independent observations is equal to the true mean μ of the population from which the data is sampled. In other words, our null hypothesis is that m = μ Formula for this test is below- halley eadNettet10. okt. 2024 · Linear Regression T Test – Lesson & Examples (Video) 1 hr.
