Common Misconceptions in Data Analysis

Misconception	Correction
Patterns and trends are the same thing.	Patterns are repeating data. Trends show a general direction of change over time.
Data analysis is just making graphs.	It involves organizing, reviewing, and interpreting data to draw conclusions.
A trend must always be increasing.	A trend can show an increase, a decrease, or even stability over time.
