"生態学的な植物調査では，植物の枯死や消失が生じうるため，0値や欠測値は珍しくない。2019年に行われた信州大学農学部の学生実習での立木調査において，多くの0値が記録された。これらの0値について，本研究では，調査票の表現を精査して生育状態を推定した。さらに，不明確な0値の生じた原因について，仕事量（調査本数）と調査の複雑さまたは単調さ（立木の生育状態の順序パターン）に注目して分析を行った。立木調査では計243本のうち82本が枯死または消失しており，さらにそのうち13本についての調査票の記録が不明確な0値であった。こうした0値は7つの学生グループのうち3グループで記録され，様々な表現が用いられていた。調査本数，立木の生育状態の順序パターン（連の数と長さ，i 番目とi+1番目の生育状態の関連性）と，不明確な0値との相関はほとんど認められなかった。よって，不明確な0値の発生には立木とは関わりのない要因が影響したと推測された。その要因としてグループ内の学生間のコミュニケーション不足が挙げられ，グループ分けの方法の改善や，0値のときの明確な表現についての指示が必要と考えられた。", "subitem_description_type":
