 note = {This study investigated the relationship between game outcomes and shot conditions by
operationally defining the difficulty of shots from a statistical viewpoint. The subjects were nationwide
elite female university basketball players. Nine shooting conditions for all shots performed in 12 games
after the quarter finals of the 66th All-Japan Collegiate Basketball Championship were observed and
checked, specifically 1) remaining seconds of the shot clock, 2) shooting methods, 3) shooting area, 4)
shooting direction, 5) play leading to a shot, 6) number of dribbles, 7) actions of players before a shot,
8) condition of offensive players facing defensive players, and 9) block shots. Logistic regression analysis
was conducted with the shot outcomes as the dependent variable and the seven items related to the
shots as independent variables.
The “difficulty of a shot” was operationally defined as the residual between the estimate from the
regressions and the actual outcome. The relationship between the prediction computed of shots for each
team and the rate of successful shots were investigated after categorizing the teams by wins and losses.
Based on regression coefficients, the average prediction computed of all shots was 0.397 (SD=0.151).
The prediction computed of all shots by wins and losses was 0.396 (SD=0.153) for winning teams and
0.398 (SD=0.149) for losing teams. Moreover, the total rate of successful shots was 39.8%, which of
winning teams was 41.2%, and that of losing teams 38.2%. No significant difference was detected in
the prediction computed of a shot and the success rate of shots. Significant relationship between the
prediction computed of shots and the success rate of shots was observed since the correlation coefficient
was 0.592 for winning teams.},
