Volleyball Stats No Easy Feat To Calculate


PHS volleyball coach Arnold Stonebrink methodically relies on statistics to monitor progress of the team and individual players. Checking team service percentages as well as individual player percentages helps coaches evaluate each player and her effectiveness.

There are several statistics involved in determining a serve percentage. Those statistics are compiled from charts kept by managers or assistants during the games.

A good chart lists each player by name and number, and records the number of service attempts, aces, errors and zero serves by each player. Aces are in-bound serves not returned by opponents, errors are not in-bounds and zero serves are in play after the serve.

Then coaches choose the statistic they want to compute. Assume Coach Stonebrink is tracking an individual’s service progress. She has 12 service attempts with four aces, one error and the rest are zero serves.

Using that information, he calculates the ace percentage by using the formula (Aces - Errors) / Total Attempts. The player has a 25 percent ace percentage, also called ace efficiency.

Next calculate each player’s serving percentage by using the formulas: (Total Attempts - Service Efficiency) / Total Attempts. Fill in the Lady Longhorn player’s variables: (12 - 0.25) / 12 = 97.9 percent.

Which means she will get the ball in play at least nine of 10 times.

Make like Robin Hood

A golden opportunity for family fun and healthy competition takes place tomorrow, Sept. 24 at the Tonto Rim Sports Club Jim Jones Shooting Range where the second “Shoot for the Rim” archery tournament will be held.

Registration opens at 7 a.m. and scores must be turned in by 2 p.m. Because a registration deadline has passed, the fees now range from $15 to $30.

Children under 14 shoot for free.

For the shoot, two different, 14 target courses, or 28 3-D targets, will be in use.

Also on the agenda is a Clout Shoot and several other games including tic-tac-toe, poker and a William Tell event in which entrants will try to shoot an apple off the head of a dummy.

Event organizer Les Conner also promises the event will include “awards, novelties, door prizes and tons of outdoor family fun.”

He also emphasizes that the tournament is a family affair and the focus will be on having fun.

“There are enough really competitive shoots, this one is for fun, but we will have awards,” he said.

Newbie’s will find the archery tournament unique in that archers, instead of shooting stationary at bull’s-eye targets, walk an outdoor course firing arrows at McKenzie life-sized 3-D foam targets of bear, deer and mountain lions.

3-D archery is a spin off of field archery that is popular among hunters because it re-creates a hunting environment with competitors shooting from unmarked distances.

Although one of the goals is hunting practice, hunting broad heads are not used because they would tear up the foam targets. Normal target or field tips are commonly used.

For the upcoming tournament, participants will compete in one of four age groups and in four separate classes based on bow types and sight.

The age groups are: Adult (18-years-plus), Youth (14-17 years), Cub (9-13 years) and Pee Wee (8 and under).

The classes include:

• Open — Archers may use any bow, sight or stabilizer.

• Release — Entrants can use any bow but with fixed pins, no scopes, 12-inch maximum stabilizers and any release.

• Fingers — Requirements include any bows, fixed pins, no scopes, 12-inch maximum stabilizers and shooting with fingers.

• Traditional — Any recurve or longbow with no sights.
