Key characteristics of a distribution "SOCS"

• Shape (Distribution)
• Outliers
• Center
• Spread (Variation)

The tree quartiles partition the data into four equally sized counts or segments.

• Minimum
• Q1
• Median
• Q3
• Maximum

The fence rule is used to fine outliers:

• Lower fence =
• Upper fence =

• Mode -- the most frequently occurring value
  • The largest bar on a bar chart or largest slice on a pie chart
  • Uni/Bi/Multi-modal -- there are multiple (nearly equal) frequently occurring values
• Distribution -- what are the possible values this variable can take and how often does it do so?
