Significance test for correlation coefficient
Did you know?
WebAs much as the correlation coefficient is closer to +1 or -1, it indicates positive (+1) or negative (-1) correlation between the arrays. Positive correlation means that if the values in one array are increasing, the values in the other array increase as well. A correlation coefficient that is closer to 0, indicates no or weak correlation. WebAt this point you will probably be sorely tempted to do a one-tailed test instead of the two-tailed one. Rather than asking "is the difference between the two correlations significant" you would want to ask "is the correlation between sleep and credits (r =.48) significantly higher than the correlation between coffee and sleep (r =.22)?"
