Definition
Trend Analysis is a method for identifying the direction and character of changes occurring in data over time.
Human Explanation
It helps determine whether observed values generally rise, fall or remain at a similar level over a defined period.
Why it Matters
Recognising trends supports Forecasting and helps organisations assess changes in operations or their environment.
Conceptual Boundary
Trend Analysis describes the direction and pattern of change, but does not by itself explain causes or prove that the observed trend will continue.
Practical Perspective
Trend Analysis is often an early step in strategic planning and Forecasting. The selected time range, data frequency, seasonality and structural changes can materially alter the apparent trend.
Common Analytical Sequence
Time Series: How are observations organised over time?
Trend Analysis: What direction or pattern is visible?
Forecasting: What may happen next?
