Improvements for tennis stats; federer vs nadal 2017 si.com

I was thinking about this year’s tennis events, and I would argue that 2017 could one day be remembered as the most important year in men’s tennis history file recovery software for windows 7 32 bit. If Federer hadn’t beaten Nadal in Australia and hadn’t later won Wimbledon, both Federer and Nadal would have 17 Slams at this point. The GOAT debate would be at its peak, and this scenario would reshape the whole discussion for years to come. I reckon Federer beating Nadal in Australia may be regarded as the most important match in tennis history and the defining match in their careers free download formatted data recovery software full version. Your thoughts?

• I’m with you on your second point best file recovery software mac free. The last half hour of the 2017 Australian Open men’s final might well be the single most important interval in the history of men’s tennis.

There’s a tennis match statistic that I would be interested in seeing: What percentage of points in which a receiver has gained neutrality do they win?


Admittedly, "gaining neutrality" in a point is subjective to some extent, but it’s always seemed to me that even when a point appears neutral, the server still has an advantage and wins more of the points. I’d like to see if this is true with real statistics, but if so, then this is a mental side of the receiving game that players could work on by trying to adjust their expectation in these points.

I’ve been reading your articles and Mailbag for a while, but writing for the first time free download sim card data recovery software full version. This is in response to the reader’s Oct. 11 comments on the use of statistics in tennis formatted data recovery software freeware. I would love to see it in next week’s Mailbag. If you do decide to use it, please feel free to edit it for length.

The reader raised the issue of lack of significance testing when reporting statistics in tennis excel file recovery software full version free download. He also seems to imply that lack of significance tests is the difference between descriptive and inferential statistics.

Two points here. Even descriptive statistics, such as cross-tabulations, can require significance tests. Second and more importantly, he misses the point of significance testing.

Their main purpose is to establish that the patterns witnessed in data are not simply true for the small sample being analyzed but can be generalized to the entire population from which the sample has been collected data recovery software for laptop free download. So if you do a survey of 5,000 or 10,000 or even 1 million randomly selected people in a country with a population of 320 million, significance tests allow you to say more confidently that your findings are true not just for those small numbers you sampled but for the whole country.

But significance testing has little meaning if you are analyzing not a sample but the entire population. In such analyses, the patterns you find are obviously true for the population as a whole.

That is what mostly happens in data-based tennis articles—or at least the ones I have come across on the ATP/WTA websites and a few other places. Analysts don’t use small samples of data about a player ease data recovery software free download. They use ALL of the data related to whatever aspect of his/her game they are analyzing. They can be perfectly confident of the reliability of their findings—way more than if they were using small samples along with reliability tests.

The reader also brings up the issue of correlation versus causation. The difference between them is not statistical but explanatory. Even regression analysis does not imply causal relationships per se, as Ross seems to suggest. Correlations can indicate causal relations too if you can meaningfully explain how one thing leads to another. So a correlation between the increase in Federer’s backhand speed, or the number of times he hits it down the line, and the increase in the proportion of points he wins against Nadal can very well indicate a causal relationship.
