Final answer:
The two types of data gathered during the evaluation phase are quantitative research data, which is numerical and can be statistically analyzed, and qualitative research data, which is descriptive and provides insights into behavior and motives.
Step-by-step explanation:
The two types of data typically gathered during the evaluation phase are quantitative research data and qualitative research data. Quantitative data consist of information that can be measured and counted, often presented in numerical form and capable of being processed through statistical analysis.
For example, when evaluating a program or survey responses, quantitative data might include demographics such as race, age, and sex, allowing researchers to identify patterns or statistical correlations within a population. An example of quantitative data in practice could be discovering that 20 percent of prisoners are above the age of 50.
On the other hand, qualitative data includes descriptive information that provides deeper insight into the 'why' and 'how' of human behavior. This type of data might come from in-depth interviews, focus groups, or content analysis, and offers rich detail that helps explain quantitative findings, such as why prisoners may take advantage of educational opportunities.
Therefore, the combination of both types of data provides a comprehensive understanding of the subject being studied and supports both reliability and validity in research findings.
