Men's 2008 Olympic (Indoor) Pool Play

I've added a chart (on which you can click to enlarge) providing a statistical summary of the just-concluded men's indoor Olympic pool play, to go along with the one for women's pool play (entry immediately below). Complicating matters, there was a three-way tie for first place in men's Group B. Looking at Group A, hitting and blocking appeared to be the key performance indicators. The higher a team finished in the win-loss standings, the better it tended to do in hitting and blocking (deviations from a perfect one-to-one relationship are shown in color fonts). It should also be acknowledged that the meanings of some of the statistics are ambiguous. One example is digging. As I noted in a posting last October, the AVCA definition of a dig is "when a defensive player keeps a bona fide attack in play with a pass." Digging an opponent's spike attempt is good, but it may reflect some weakness in the defensive team's blocking, as balls would be

Women's 2008 Olympic (Indoor) Pool Play

With pool play now complete in the Olympic women's (indoor) volleyball competion, I've created a table (below) to let readers see how the final standings in each of the two pools (first through sixth place) track with how the teams have ranked thus far (before medal play) in six statistical performance areas . (You can click on the table to enlarge it.) A perfect correlation is represented by all of the numerals appearing in black font, such as Group B's rankings on hitting percentage. Brazil, which finished first in its pool with a 5-0 record, also had the highest team hitting percentage in the pool; Italy (4-1), which finished second in the pool, also had the second-highest hitting percentage; the trend continued all the way down to sixth-place finisher Algeria, which was also sixth in hitting percentage. Discrepancies are shown in color fonts (the specific colors don't really mean anything, they're just used to draw attention to the numbers). For Group A

NBC Olympics Website for Volleyball Stats

The NBC Olympics website is now providing extensive (indoor) volleyball statistics -- hitting, blocking, serving, digging, setting, and receiving. Further, hitting percentage is now being calculated correctly (subtracting errors from successful kills, before dividing by attempts). Clicking here leads you to men's statistics at the team level, but from that page you can click on a heading to get to women's statistics, as well as varying whether you get team or individual statistics. Pool play ends this weekend for both men and women; upon conclusion of this stage of the competition, I'll present some analyses of how the pool winners did in the various statistical categories. Statistics are available in a similar format for men's and women's beach volleyball , but there seem to be a lot of holes in the numerical information provided. There's already been a lot of excitement for the U.S. teams in the sand, as the legendary women's duo of Misty May-Treano

NBC Olympic Announcers Sunderland and Barnett Informative on Strategy and Stats

NBC's late-night Tuesday/early-morning Wednesday Olympic coverage featured a women's (indoor) volleyball match between the U.S. and Venezuela, ultimately won 3-1 by the Americans. Thus far, I've found announcers Paul Sunderland (a member of the 1984 U.S. men's gold-medal team ) and Kevin Barnett (an Olympian of more recent vintage ) to be informative on strategy and statistics. As Game 4 got underway, Barnett (I believe, rather than Sunderland) asserted that U.S. blocking (7 in Game 3 alone) and Venezuela's poor serving (1 ace compared to 12 errors, through three games) were the "dictating statistics of this match." According to the final box score , the Americans indeed outperformed the Venezuelans in blocking, 16 to 6. Jen Joines , who entered the match in a substitute role for the U.S., was singled out for accolades by the announcers. The announcers also stressed the importance of playing "in system." By this, they mean consisent, qual

Following Statistical Aspects of the 2008 Summer Olympic (Indoor) Volleyball Competitions

With the Summer Olympics underway in Beijing, I would like to welcome everyone to VolleyMetrics, where I'll be presenting statistical analyses of several of the volleyball matches and taking comments from interested viewers. Before starting, I would like to offer condolences to the Bachman and McCutcheon families for the tragic attack that took place earlier. First, for results and boxscores of (indoor) volleyball, you can go to the following link (I may add in some postings on beach volleyball, I'm not sure): As some of you may have seen this morning on television in the U.S., the American women opened up with a 3-1 victory over Japan. The boxscore for this match is available here . Two of the major topics I have emphasized on this blog are hitting percentage and defending against opponents' hitting via blocking and digging . If you look at the boxscores provided through the NBC Olympics website, you&
