Final answer:
Collecting physiological data during music therapy interventions typically yields quantitative data, whether it's quantitative continuous data like duration or quantitative discrete data like the number of sessions. Qualitative data is used for understanding personal experiences and is often collected through methods like participant observation, especially when studying thought processes or experiences that cannot be directly observed.
Step-by-step explanation:
Collecting data about physiological responses to music therapy (MT) interventions would most likely yield quantitative data. This type of data is numerical and can be measured in a precise manner. For example, when recording the duration of a music therapy session, the amount of time spent would be considered quantitative continuous data since it is measurable over a continuous range. Likewise, if noting the number of times per week MT sessions occurs, this would be quantitative discrete data as it refers to a count of discrete events. Symbolic interactionists are more inclined to use participant observation as a research technique, focusing on qualitative data. Qualitative data, which is nonnumerical, such as language or impressions, is important, especially when considering personal experiences.
When examining the validity and reliability of measurements in research, these terms pertain to the quality of the data. Reliable measurements are those that yield consistent results, while valid measurements accurately reflect the concept being studied. Using secondary data is a method of research considered to be nonreactive because it doesn’t involve direct contact with the research subjects. When looking for trends in data, one is most likely using analytical intelligence to discern patterns and make sense of the information collected.
