Needs assessment is a process of identifying and prioritizing the needs of a population or community. It is not a type of program evaluation, which is a systematic and objective process for determining the effectiveness of a program.

Process evaluation is a type of program evaluation that focuses on assessing the implementation of a program. The purpose of process evaluation is to identify the strengths and weaknesses of a program, assess its efficiency, and determine whether it is being implemented as intended.

Experimental design is a method of research that involves manipulating one or more independent variables to observe the effect on a dependent variable. It is not a method of data collection, which is the process of gathering information about a program.

Outcome evaluation assesses the effects of a program on the participants, while impact evaluation assesses the effects of a program on the community. Outcome evaluation is typically more quantitative, while impact evaluation is typically more qualitative.

Stakeholder involvement is important in program evaluation because it ensures that the evaluation is relevant and useful, helps to build support for the program, and can help to identify potential problems with the program.

Policymakers are not typically considered stakeholders in program evaluation, as they are not directly involved in the implementation or operation of the program.

A logic model is a visual representation of a program's theory of change. It identifies the program's goals and objectives, and it provides a plan for implementing the program.

Meta-analysis is a statistical method that is used to combine the results of multiple studies. It is not a type of data analysis method in program evaluation, which typically involves descriptive statistics, inferential statistics, and qualitative analysis.

The purpose of a program evaluation report is to communicate the findings of the evaluation to stakeholders, make recommendations for improving the program, and hold the program accountable for its results.

Mixed methods design is not a type of program evaluation design. It is a research design that involves collecting and analyzing both quantitative and qualitative data.

Formative evaluation is conducted during the planning and implementation stages of a program, while summative evaluation is conducted at the end of a program. Formative evaluation is used to improve the program, while summative evaluation is used to make decisions about the program. Formative evaluation is typically more qualitative, while summative evaluation is typically more quantitative.

Experimenter bias is not a type of bias in program evaluation. It is a type of bias that can occur in experimental research when the experimenter influences the results of the study.

The purpose of ethical guidelines in program evaluation is to protect the rights of participants in the evaluation, ensure that the evaluation is conducted in a fair and unbiased manner, and promote the use of evidence-based decision-making.

Feasibility is not a type of program evaluation standard. It is a factor that is considered when designing and conducting an evaluation.

Theory provides a framework for understanding the program and its effects. It can be used to develop hypotheses about the program's effects and to design the evaluation.
