When a research inference based on a sample holds true for the universe, it is called:

When a research inference based on a sample holds true for the universe, it is called: 1. Abstraction 2. Verifiability 3. Generalization 4. Replicability

The correct answer is 3. generalization.

Generalization is the process of inferring from a sample to a population. When a research inference based on a sample holds true for the universe, it means that the inference can be generalized to the entire population.

Abstraction is the process of simplifying a complex idea into a more general one. Verifiability is the ability to test a claim to see if it is true. Replicability is the ability to reproduce a research study and get the same results.

Here are some examples of generalizations:

• A researcher finds that a new drug is effective in reducing cholesterol levels in a sample of patients. The researcher can generalize this finding to the population of all patients with high cholesterol.
• A researcher finds that a new educational program is effective in improving student achievement in a sample of schools. The researcher can generalize this finding to the population of all schools.
