Here's a little surprise. We hear all the time how Morne can't tackle. So what do we find if we look at all the games Morne and Lambie played at flyhalf in the S15?
Well we find Morne makes a total of 121 tackles for an average of 8.06 tackles per game. Lambie makes 103 tackles for an average of 7.3 per game.
And in terms of success rate, Lambie scores a very admirable 90.3% success rate. And Morne? Why he has exactly the same 90.3% success rate.
Here ends Myth Number O ne.
Another misleading use of stats - what was the made and missed tackle ratio - which is of essence in evaluating real value in this case. Morne made the same percentage of missed tackles as Lambie - but the massive myth you created of Morne being so much superior ends here.
The only thing Morne was really superior in was his goal kicking percentage of 79% against the 75% of Lambie. But even here the 50% success rate of Morne in the pressure semi-final game of the Bulls contributed massively to the loss of the game by the Bulls. Here we must add the miserable relieving kick of Morne as a defensive matter - which ended up as a try for the Br umbies - the final nail in the coffin of the Bulls.
The latter info is not a myth - it is reality.

Sorry - but I think it was clear in this case. Mozart said that Morne made 121 tackles as against the 103 of Lambie. He gave the success rate as 90.3% in both cases. Lets accept the said scenario as correct.
So for a 90,3% success rate it means statistically that Lambie missed 10 tackles as against the 14 missed by Steyn - really an insignificant number in the series as a whole and is not really of major statistical or practical value in this case. It does not prove anything as a major difference between the two players - a difference Mozart tries to assign as of particular value to Steyn as being superior to Lambie.
Let me make things plainer for you OOM.
1) The null hypothesis is Lambie is a better tackler than Morne. That's what you and Dave have been claiming over and over. This test just deals with that issue. The sample size at 14 plus games is very adequate....so we can have some confidence in the data.
2) The results show that their success rate is exactly the same at 90.3% of their attempted tackles made. A very high number.
The only significant difference is Morne attempts 8.93 tackles a game and makes 8.06......Lambie attempts 8.14 tackles a game and makes 7.3. To me over a long season of tackling, that difference, of 11.5% more tackles per game by Morne than Lambie, looks significant.
So the null hypothesis is defeated....if we wanted to do more work and calculate variances in tackling success and tackles attempted, a confidence level for this statement could also be calculated....but it will be well north of 90%. The null hypothesis is toast.
The numbers do not prove that Lambie is a better tackler than Morne. That's all.
