• Paul Felix Lazrsfeld - founder of modern research surveys and contextual analysis
• Practical research involves observation, collection, documentation, analysis, interpretation, and communication of results
• Qualitative research focuses on the dynamic behavior of customers, systems, and trends affecting sales, production, and marketing
• Quantitative research describes, measures, quantifies, makes hypotheses, and tests relationships and variables relating to sales, production, and marketing
• Characteristics of good research include being empirical, logical, analytical, critical, replicable, innovative, and ethical
• Replication in research involves an independent group of researchers copying someone else's work to arrive at the same results, strengthening the validity of the results
• The value of research includes reducing risk, providing better references for decision-making, and benefiting education, business, society, and the economy
• Quantitative research collects numerical data, applies statistical analysis, and involves a sample size determined before data collection
• Quantitative research designs include experimental and non-experimental designs
• Experimental research determines cause-and-effect relationships by manipulating the independent variable and measuring the outcome through the dependent variable
• In experimental research, there are two groups: the experimental or treatment group and the control group
• Types of experimental research designs include true experimental and quasi-experimental designs
• Non-experimental research describes collected data about a subject and determines relationships or connections without manipulating an independent variable or random assignments
