Research provides us with a variety of information that helps us understand the world around us. Here are some key types of information research gives us:

- Quantitative Information: This is numerical data that can be measured and analyzed statistically. Examples include measurements of height, weight, blood pressure, and IQ scores.

- Qualitative Information: This is non-numerical data collected through observations, interviews, and other subjective methods. Examples include descriptions of emotions, attitudes, beliefs, and behaviors.

- Primary Information: This is information collected directly from the source, such as through experiments, surveys, and interviews. It's generally considered more reliable than secondary information.

- Secondary Information: This is information gathered from existing sources like books, articles, and databases. While useful, it's important to verify its accuracy and reliability.

- Empirical Information: This is information based on observation or experience rather than theory or speculation. It's typically considered more reliable than non-empirical information.

- Theoretical Information: This is information based on theories or hypotheses. It can be helpful in developing new ideas and concepts but needs to be tested empirically to verify its accuracy.

Research helps us:

- Formulate research questions: By understanding the current state of knowledge, research helps us identify gaps and formulate relevant research questions.

- Design studies: Research provides the theoretical framework, concepts, and methods necessary to design effective studies.

- Collect data: Research guides us on what types of data to collect, how to collect them, and how to ensure data quality.

- Analyze results: Research equips us with the statistical tests and techniques needed to analyze data and draw valid conclusions.

- Draw conclusions: Research helps us interpret findings in light of existing knowledge and make informed recommendations for future research.
