Statistical Significance must Go!!! (P value arbitariness) do they correlate with the clinical significance?
A New Year's resolution for all of us:
Let's make 2018 the year in which scientific journals said goodbye to statistical significance. We just won't type "statistically significant" in our papers, even if asked by clueless reviewers and editors. Simple way for editors to improve science: If your journal still uses “statistical significance” in 2018, retire your statistical consultan. https://twitter.com/i/moments/864222884000129025 [taken from JiSC MAILserve]
Statistically significant may not be significant in real world. For example if drug A causes reduction in flu symptoms by 5.5 days over drug B which causes reduction of flu symptoms by 5.3 days is statistically significant with p <0.01

The Futility of Significance (Statistical, that is)
A wonderful surprise arrived in my gmail inbox this morning. A message from Neil Thomason, a dear colleague of mine, who sends me interesting things to read from time to time. It’s not that much of the time the things Neil sends me aren’t that interesting. It’s just that the interesting things he does send me only come from time to time.
Last time he sent me something, it was this Many Labs paper on replications available at the Open Science Forum. Clearly, Neil was impressed. Ten of 13 classic effects were well replicated, one was so-so, and two were not replicated. Neil must have thought I was having a bad day when I clearly was not sharing in the joy. The main reason for that has to do with the fact that effects and explanations of effects are seldom properly decoupled. As a result, a replication of a classic effect is often communicated as a replication of the explanation of the effect. But of course an effect can be highly replicable yet explained in an entirely improper manner. I believe that the authors of the Many Labs paper fell into that trap of not adequately separating the effects they replicated from the standard interpretations given to them. I went on in my reply at some length about the inherent dangers of doing so (and I should blog about this in a separate post at some point in the future).
I confess that I was disappointed not to get a reply from Neil since I thought my comments posed a thoughtful reply to his exuberant reaction. I thought those comments would spark a lively discussion of the issue, perhaps leading us toward some sound principles to guide similar future endeavours. Neil is after all a philosopher of science.
At any rate, nearly 3 months later, this morning, I got a message from him. Just this link to a blog post by Matthew Hankins entitled “Still Not Significant.” I really enjoyed the post, which deals with the many creative ways researchers find to describe their results when their statistical significance values are at or greater than the magical p < 0.05 level. I encourage you to read the post, but just in case you’re too busy or lazy to do so, I’ve reproduced the list of circumlocutory expressions quoted there. I warn you, the list is long, but also entertaining:

One blogger even went so far as to implement the list in R so that when a significance level between .05-.12 is registered, it randomly selects one of those “p excuses” to describe the result.
Hankins’ advice is not to waffle: if your p value is below 0.05 (or presumably whatever you set your alpha level to), your result is significant. If it’s at or over that value, it’s not significant. No “marginal” in betweens or creative expressions such as “very closely brushed the limit of statistical significance (p=0.051).” By the way, does anyone not see a counterfactual thinking study here just waiting to be exploited? (Recall “The loser that almost won” by Kahneman and Varey 1990).
In a related blog post, Hankins shows this wonderful figure he generated from Google Scholar search results.
It certainly makes a point. We have a problem when p = 0.10 is described as marginally significant more frequently than values between 0.050 and 0.094.
And Hankins’ comments in the figure essentially capture the psychology of significance test reporting.
But something about the advice just doesn’t make sense to me. Hankins, like most of us, realizes that the 0.05 level is arbitrary. How could it be, then, that it makes sense to describe one’s results as significant when p is just below that arbitrary value — say 0.049 — while an ever so slightly different result — say 0.050 — ought to be instead labelled not significant.
Is this not the path to madness?
Perhaps the use of “marginally significant” is also partly an attempt by researchers to cope with the craziness of an arbitrary cutoff that defines whether they are to claim their results are “significant” or not.
Marginality at least allows a grey zone around the point of insanity to be defined. The problem is not the grey zone, but rather the use of the arbitrary cutoff.
As I noted in my reply to Neil, although more journal editors and reviewers are calling for effect sizes, most still expect some significance testing to accompany that.
Perhaps it would be wiser to stop calling the p values we standardly report “significance” values, and instead call them what they are: the probability of data given the null hypothesis is true.
Doing that would have two immediately beneficial effects. First, it would correctly define those values, which are often misinterpreted as 1 – the probability of the experimenter’s hypothesis being true, given the data. For instance, one commenter states “All a p-value of 0.05 means is there’s a 95% chance that the hypothesis was indeed working.” Second, it would get us away from the arbitrariness of p < 0.05.
In the end, the circumlocution researchers use in describing the results of their significance tests may not be excusable, but it is understandable not only as a tactical maneuver to keep studies out of the unpublished file drawer, but also as a means of coping with the senseless arbitrariness of a point that separates a continuum into two alternatives: significant or not.
