How do you find the critical value of a Pearson correlation?
Consult the table for the critical value of v = (n – 2) degrees of freedom, where n = number of paired observations. For example, with n = 28, v = 28 – 2 = 26, and the critical value is 0.374 at a = 0.05 significance level.
What is critical value in Pearson r table?

What is Pearson correlation table?
The table contains critical values for two-tail tests. 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. …

What is z score in statistics?
A Z Score, also called as the Standard Score, is a measurement of how many standard deviations below or above the population mean a raw score is. Meaning in simple terms, it is Z Score that gives you an idea of a value’s relationship to the mean and how far from the mean a data point is.
What is Pearson’s correlation table used for?
The Pearson’s Correlation Table, which contains a table of critical values of the Pearson’s correlation coefficient. Used for hypothesis testing of Pearson’s r.
How do you map a z score across a Z table?
To map a Z score across a Z Table, it goes without saying that the first thing you need is the Z Score itself. In the above example, we derive that Eric’s Z-score is 0.56. Once you have the Z Score, the next step is choosing between the two tables.
How do you find the second decimal from Eric’s Z score?
Since Eric’s Z score value is positive, we will use the Z-table with positive values (Table 1.2). Find the corresponding value for the first two digits on the y axis (0.5 based on Eric’s Z score). Once you have that, go alongside the X axis to find the value for the second decimal (0.06 based on Eric’s Z score). We get the number 0.7123.
