WebLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833.

WebCritical value may refer to: In differential topology, a critical value of a differentiable function ƒ : M → N between differentiable manifolds is the image (value of) ƒ(x) in N of a critical point x in M. In statistical hypothesis testing, the critical values of a statistical test are the boundaries of the acceptance region of the test. WebSep 9, 2024 · Common Values for z α/2. The following table displays the most common critical values for different values of α: The way to interpret this table is as follows: For a test using a 90% confidence level (e.g. α = 0.1), the z critical value is 1.645. For a test using a 95% confidence level (e.g. α = 0.05), the z critical value is 1.96. WebJul 8, 2024 · The following table shows formulas for the components of the most common confidence intervals and keys for when to use them.
