a correlation in which large values of one variable are associated with small values of the other; the correlation coefficient is between 0 and -1

ある変数の大きな値が別の変数の小さな値と関連付けられる相関関係であり、相関係数が0から-1の範囲にある

a correlation in which large values of one variable are associated with large values of the other and small with small; the correlation coefficient is between 0 and +1

大きな値を持つ一つの変数がもう一つの大きな値と関連し、小さな値が小さな値と関連する相関関係。相関係数は0から+1の間にある

a correlation between two variables (e.g., between the number of electric motors in the home and grades at school) that does not result from any direct relation between them (buying electric motors will not raise grades) but from their relation to other variables

2つの変数（例えば、家の中の電動モーターの数と学校の成績）の間に直接的な関係はないが、他の変数との関係から生じる相関関係のこと。

a correlation between two variables when the effects of one or more related variables are removed

一つ以上の関連する変数の影響を取り除いたときに二つの変数の間に見られる相関関係

any correlation in which the rates of change of the variables is not constant

変数の変化率が一定でない相関関係

the use of statistical correlation to evaluate the strength of the relations between variables

統計的な相関関係を用いて変数間の関係の強度を評価すること
