Study Notes

Quantitative Methods (QM)

Definition: QM emphasizes objective measurements and the statistical, mathematical, or numerical analysis of data. Data is typically collected through polls, questionnaires, surveys, or by manipulating pre-existing statistical data using computational techniques.
Purpose: QM focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon.
Common Uses:
- Survey Research
- Correlational Research
- Experimental Research

Qualitative Research

Definition: A market research method that focuses on obtaining data through open-ended and conversational communication.
Purpose: To understand "what" people think and "why" they think so.
Common Uses:
- One on One Interview
- Case Study Research
- Focus Groups
- Record Keeping
- Ethnographic Research
- Process of Observation

QM Scope

Typically involves designing experiments or surveys, gathering measurable data, and analyzing this data using mathematical models to draw conclusions or make predictions.
Valuable for their precision and ability to handle large volumes of data, making them crucial for informed decision-making and validating theories.

Significance of QM

Objective Analysis: Provides a framework for obtaining objective data that can be universally measured and analyzed, reducing the influence of personal biases and subjectivity in interpreting results.
Generalizability: Using statistical methods to analyze data from a sample, quantitative research allows for conclusions that can be generalized to a larger population.
Predictive Capabilities: Involves developing models to predict outcomes based on measurable variables. This is essential in fields like weather forecasting, finance, and logistics.
Replicability: The structured nature of quantitative research, emphasizing precise measurement and replicable procedures, ensures that studies can be repeated. This is key to verifying results and building on existing knowledge.
Statistical Validity: Uses statistical tools to validate hypotheses. Provides a robust framework for testing theories and establishing facts with a known degree of accuracy.
Decision Making: Used to make informed decisions in business and policy-making. For example, analyzing customer data to optimize strategies and meet market demands.

Categories of QM

Surveys and Questionnaires:
- Purpose: To collect data from a large group of people efficiently.
- Method: Standardized questions are used, ensuring consistency and comparability of responses.
- Application: Common in market research, sociology, and health studies to gauge public opinion, satisfaction, or behaviors.
Experiments:
- Purpose: To determine cause-and-effect relationships by manipulating variables.
- Method: Participants are typically divided into control and experimental groups to test the impact of specific changes.
- Application: Widely used in scientific research, psychology, and medicine, such as testing new drugs or psychological interventions.
Longitudinal Studies:
- Purpose: To track changes over time.
- Method: Data is collected from the same subjects repeatedly over a prolonged period.
- Application: Useful in developmental psychology, education, and health sciences to study changes across the lifespan or the effects of long-term interventions.
Secondary Data Analysis:
- Purpose: To analyze existing data collected for other research purposes.
- Method: Involves the statistical analysis of data from government databases, historical records, or previous research studies.
- Application: Economists, historians, and policy analysts often use this method to conduct large-scale studies without requiring direct data collection.

Attributes of QM

Structured Tools: QM relies on structured tools such as surveys, polls, or questionnaires to gather quantitative data. These structured methods help collect in-depth and actionable numerical data.
Sample Size: QM is conducted on a significant sample size representing the target market. Appropriate sampling methods are essential to ensure the reliability of the results.
Close-ended Questions: Close-ended questions, specifically designed to align with research objectives, are a cornerstone of quantitative research. These questions facilitate the collection of quantitative data.
Prior Studies: Before collecting data, researchers often delve into previous studies related to the research topic. This preliminary research helps frame the study effectively and ensures the data collection process is well-informed.
Quantitative Data: Typically, quantitative data is represented using tables, charts, graphs, or other numerical forms. This visual representation aids in understanding the collected data and is essential for data analysis.
Generalization of Results: One of the strengths of quantitative research is its ability to generalize results to the entire population. The findings derived from a sample can be extrapolated to make informed decisions and take appropriate actions for improvement.

Implementation of QM

Business and Economics:
- Market Research: QM is used to understand market trends, consumer preferences, and buying behaviours.
- Financial Analysis: QM is used to predict market movements, assess investment risks, and evaluate economic policies.
- Real-Time Code: QM is crucial for proving that code will execute on time without missing its window of response, regardless of the decision paths taken in the code or interrupts handled.
Healthcare: Used in clinical trials, disease surveillance, and healthcare resource allocation.
Social Sciences: To study social trends, public opinion, and social inequalities.
Education: To measure student learning outcomes, evaluate teaching methods, and analyze school effectiveness.
Science and Engineering: To conduct experiments, analyze data, and develop new technologies.
Environment and Geography: To study environmental impacts, monitor climate change, and manage natural resources.
Information Technology: To analyze user behaviour, optimize system performance, and develop data-driven solutions.

Benefits of QM

Collect Reliable and Accurate Data: QM is a powerful method for collecting reliable and accurate data. Since data is collected, analyzed, and presented in numbers, the results are incredibly reliable and objective.
Quick Data Collection: Quantitative research involves studying a group of people representing a larger population. Researchers use a survey or another quantitative research method to efficiently gather information from these participants, making the process of analyzing the data and identifying patterns faster.
Wider Scope of Data Analysis: Offers an extensive range of data collection and analysis due to its utilization of statistical methods. Researchers can delve into a broader spectrum of variables and relationships within the data, enabling a more thorough comprehension of the subject.
Eliminate Bias: QM eliminates bias, as the findings are presented in numerical form. This objectivity makes the results fair and reliable, reducing the potential for researcher bias or subjectivity.
Cost-Effective: QM can be more cost-effective than qualitative research, especially when collecting data from a large sample.
