WebEntering table B at 15 – 2 = 13 degrees of freedom we find that at t = 5.72, P < 0.001 so the correlation coefficient may be regarded as highly significant. Thus (as could be seen immediately from the scatter plot) we have a very strong correlation between dead space and height which is most unlikely to have arisen by chance. Web11 Apr 2024 · To recap, we took our A/B test result of $7.7 per visitor and decided that this value is unlikely to occur if, in reality, both Test and Control populations have identical means. More formally, our p-value of 0.02 is less than our significance level of 0.05 and so we reject the null hypothesis.
