查询词典 distributed

In a scatter diagram, when the dots are distributed roughly along an ascending tendency, there is a positive correlation between the two sets of data. On the contrary, when the dots are distributed rough along a descending tendency, there is a negative correlation. However, when the dots scatter irregularly without a pattern, there is no obvious correlation.
