• Intersections : Do we observe any important intersections or overlaps between
variables, crossover points that indicate a significant change in relationship?
Using a line chart is a perfectly suitable method to observe patterns and
trends, as we see below:
Relationships and connections:
• Exceptions : Can we identify any significant values that sit outside of the
norm, such as outliers that change the dynamics of a given variable's range?
• Correlations : Is there evidence of strong or weak correlations between
variable combinations?
• Associations : Can we identify any important connections between different
combinations of variables or values?
• Clusters and gaps : Where is there evidence of data being "bunched"? Where
are there gaps in values and data points?
