Why this is mistaken
Pair center with ordered values or a plot and a spread measure. Juniper Year 2's mean of 29.375 days hides a 26.5-day median, a dense 18–35-day cluster, and a 78-day tail observation.
Where to watch
When this mistake may appear
- A dashboard displays one average.
- Two groups have similar means.
Check your work
Your work may contain this mistake if:
- Ignores Juniper's 78-day observation.
- Calls equal means equivalent performance without comparing spread or shape.
