Question: 1 / 400

In data analysis, what signifies a trend in response measure graphs?

A series of data points with no observable pattern

A consistent increase or decrease over time

A trend in response measure graphs is indicated by a consistent increase or decrease over time. This reflects a predictable pattern or direction in the data collected, demonstrating that the behavior being measured is changing in a systematic way.

When professionals analyze behavior, trends help them understand the effectiveness of an intervention or the natural progression of behavior without external influences. A consistent increase suggests that the behavior is being reinforced effectively, while a consistent decrease may indicate that the behavior is being diminished or that interventions are less effective. Observing trends allows behavior analysts to make informed decisions about treatment and adjustments needed to optimize outcomes.
