Nope!
- AstralStorm 11y agoIndeed, what it might have meant is "strictly on the basis of p-values" or confidence intervals. Still, that is very risky, p-values attained using different tests cannot be compared. Not to the point, p-values have no meaning if you do not have a control group, because you do not have access to a population that might be under the null hypothesis. P-values are sometimes computed against a non-null hypotheses, e.g. null test is giving people $5 not nothing, while the main gives $100. This is not valid. Or against the same subgroup, which might not really be representative.
- nonbel 11y agoI don't think your point is the same as mine. The p-value only tells you how likely it is to see a deviation at least as extreme as the data you plugged into the equation, if the model you are testing were true. That's it.
