A graph in which paired values for two variables are plotted as individual points.
Revise: Data AnalysisA scatter diagram investigates a possible relationship between two numerical variables. Each individual or location contributes one point whose horizontal and vertical coordinates are its paired measurements. The points are not joined in sequence.
Describe a scatter diagram precisely: positive correlation, negative correlation or no correlation. Refer to both named variables when explaining the trend.
Describe a scatter diagram with the words positive correlation, negative correlation or no correlation, then refer to the pattern of points.
