Pearson r level of significance

WebDec 15, 2024 · Pearson’s Correlation Table The table contains critical values for two-tail tests. For one-tail tests, multiply α by 2. If the calculated Pearson’s correlation coefficient is greater than the critical value from the table, then reject the null hypothesis that there is no correlation, i.e. the correlation coefficient is zero. WebIf r< negative critical value or r> positive critical value, then ris significant. Since r = 0.801 and 0.801 > 0.632, ris significant and the line may be used for prediction. If you view this …

WebThis is because the 0.05 level of significance is less stringent than the 0.62 level. However, if the critical value at the 0.01 level of significance is 0.62, then the value that was obtained would not be considered statistically significant because it is lower than 0.62. This is because the 0.62 threshold represents statistical significance.
