Which of the following is NOT a method of property data collection?

Qualitative Analysis is correctly identified as not a method of property data collection because it refers to a research approach focused on understanding and interpreting non-numerical data, such as opinions, experiences, and motivations. In the context of property evaluation, qualitative analysis is more about analyzing the underlying characteristics and themes of data collected through other methods rather than being a primary means of collecting raw data itself.

On the other hand, field surveys, case studies, and random sampling are all recognized methods used to gather property data. Field surveys involve direct observation and measurement of property characteristics, facilitating accurate data collection in real-world environments. Case studies provide in-depth insights into specific properties or market situations, utilizing collected data to draw conclusions about trends or patterns. Random sampling is a statistical technique that ensures various properties are selected randomly for data collection, thereby enabling the evaluator to infer broader trends across a population from the sample.
