No, it is not true that “any sample size less than 21 is statistically irrelevant.” In general, a result has greater “statistical power” as we increase sample size, but also as we increase effect size. You’re looking at games-played (I think) and concluding that’s not a big enough sample. But you could also (as I am) look at the number of players, which in this case is more than 20 if you consider only Kings players, and more than 600 if you look at NHL players. And the effect size (winning more than 7 out of 10 games) is sufficiently big that a smaller sample size may still yield a significant result.

There is one player who has played more than 20 games and who has a W% of greater than .700. There are two who have played more than 10 games. There are four who have played more than 5 games. The question is what criterion do you accept for “statistical significance.” One might apply a 1/1000, 1/100, 1/20 or 1/5 threshold, depending on context.

If Quick started 15 games and his record was 0-15, no one would say that was statistically insignificant. Even though you might choose to define sample size as “15 games played.” I could define the sample size as “60 goaltenders in one season.” In any case, the chance of Quick randomly losing 15 games in a row is very tiny (.00003). So you would say that this result is significant since by occurring once in 100 years with merely a few hundred goalies (as opposed to the odds of it occurring randomly: 3/100000) it has far exceeded the significance criterion.

]]>The problem isn’t coaching. The problem is the players…Sturm has been hurt, so you can’t really bash him for his play. when healthy, he’s always been a top 6 forward.

Poni hasn’t done much over the course of the season..He has had a few games where you see the skill and what could be…just not enough. He’s played 33 games and has 8 points. Not sure where you’re seeing the goals he’s scored, but it hasn’t been for us.

Seniority? when you’re battling for your playoff lives, you can take seniority and throw it out the window. It’s all about earning your playing time.
