"Plus-minus" nghĩa là gì?

Đôi khi cho chắc cú, 1+1 tôi cũng phải tính máy tính. Photo by Kaboompics .com from Pexels

"Plus-minus" hoặc "plus or minus" = cộng-trừ -> nhiều hơn hoặc ít hơn, đại khái, ưu điểm/khuyết điểm. Đây còn là phương pháp tính toán sự hiệu quả của một cầu thủ chơi khúc côn cầu.

Ví dụ
The Hill-HarrisX poll was conducted online among 1,001 registered voters between March 8-9. It has a margin of error (biên sai số) of plus or minus 3.1 percentage points.

A strange thing is taking place on one of the two best teams in the Western Conference. Colorado Avalanche defenceman (cầu thủ phòng thủ) Ryan Graves is – and I believe I have this right – plus-one million on the NHL season to date.

A majority of Democrats (Đảng Dân chủ) say a primary would be better (64%), as do a plurality (đa số) of Republicans (Đảng Cộng hòa) (43%). The poll, conducted by Selzer & Co., interviewed 800 Iowa adults and had a margin of error of plus or minus 3.5 percentage points.

Andre Iguodala is still getting settled (ổn định) into his new team and role with the Miami Heat. The 36-year-old wing has only played seven games this season and as a result, the former All-Star’s -5.4 plus/minus stat from this season leaves much to be desired (mong muốn).
