How do you figure out the p value
WebPause the video and try to figure that out. So let's first of all remind ourselves what a p-value even is. You could view it as the probability of getting a sample proportion at least this large if you assume that the null hypothesis is true.

WebOct 16, 2014 · If the value from the first calculation is stored in cell A1, we can write: =tdist (A1, 17, 2) Which gives a result of p = 0.059. Should you ever want to calculate a critical value for a Pearson correlation, the process is reversed. You first calculate the critical value for t, and then you convert this into r.
WebIn general, when comparing two means, the t-test is used. Note from the results given above by ericp, that the conclusion from either test is the same. The two groups differ significantly. In scientific reports, p-value is reported to 2 decimal places. So using either the z or t test, you would report a significant difference "with p < .01".
