The Q statistic is 19.3179, as compared with an expected value of 4. The p-value is 0.0007 . This p-value meets the criterion for statistical significance. It seems clear that there is substantial dispersion, and probably more than we would expect based on random differences. There probably is real variance among the effects.

We would be trying to find a value of z* such that. P(z < -z* or z > z*) = .05. Since the standard normal distribution is symmetric, the most extreme 5% would be equally divided between the high side and the low side of the distribution, resulting in an area of .025 for each of the tails of the z curve. ... Convert z* back to x* for by . x ...
