What is a time-series measurement design?

1. A method that uses only one group at one point in time

2. A design that observes a single subject over time with multiple measurements

3. A technique that compares two different groups at the same time

4. A method focused solely on qualitative data

The correct answer is: A design that observes a single subject over time with multiple measurements

A time-series measurement design is characterized by observing a single subject or group over an extended period, while collecting multiple measurements at various time points. This approach allows researchers to track changes over time, identify trends, and analyze the impact of interventions or variables on a subject's or group's behavior or responses. By employing multiple measurements, the design can provide a richer dataset, enabling the researcher to capture fluctuations and patterns that may not be evident through a single measurement, thus offering insights into the dynamics of change. This method is particularly valuable in fields such as psychology, education, and health research, where understanding temporal patterns is crucial for developing effective strategies and interventions.
