The common table chi alpha
WebThe hypothesized pattern = the null hypothesis. p < alpha => rejected. Analysis: o Calculate a Chi-square (χ2) value o Chi-square table => p-value o p < alpha is statistically significant o observed data ≠ the hypothesized pattern o Chi-square = 0 o observed data = the hypothesized pattern. o Large values indicate deviations from this

The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: 1. The degrees of freedom for the Chi-Square test 2.

WebApr 1, 2024 · When reporting chi-square values in a table, include the degrees of freedom in parentheses: chi-square (df). The abbreviation for degrees of freedom (df) does not need to be expanded; it should be italicized (AMA glossary of statistical terms, section 19.5). Examples: In text: χ 2 4 =0.3. In table: Chi-square (df) --> 0.3 (4)
