1. errors and biases in consumer research

Consumer research is a process of collecting and analyzing consumer-related data to obtain consumer information and insights. Consumer research can use different methods, such as questionnaires, in-depth interviews, focus groups, experiments, observations, etc. The purpose of consumer research is to help companies better understand consumer behavior, attitudes, motivations, needs, preferences, satisfaction and loyalty, so as to develop more effective marketing strategies, such as product development, pricing, distribution, promotion and brand management.

However, the results of consumer research are not always accurate and reliable, and there may be various errors and deviations that affect the quality and value of the research. Error refers to the difference between the research results and the real situation, and deviation refers to the systematic deviation between the research results and the real situation. Errors and deviations may come from the design of the survey, data collection, data analysis and data presentation, which may involve the objectives, scope, methods, samples, tools, technology, personnel, time, cost and other factors of the survey.

Depending on the source and nature of errors and biases, errors and biases in consumer research can be classified into the following types:

Sampling error: refers to the error caused by the research sample is not fully representative of the population, such as sample size, selection, stratification, weight, etc.

Non-sampling error: refers to errors other than sampling error, such as missing data, errors, anomalies, etc.

Measurement error: refers to errors caused by inappropriate or inaccurate research tools or techniques, such as questionnaire design, coding, testing, revision, etc.

Response error: refers to the error caused by the non-cooperation or dishonesty of the research object or personnel, such as refusal to participate, random answer, social expectation, recall deviation, etc.

Analytical error: refers to the error caused by improper or incorrect data processing or interpretation, such as data cleaning, conversion, statistics, modeling, inference, etc.

Presentation error: refers to errors caused by unclear or inaccurate presentation or communication of data, such as data visualization, reporting, communication, etc.

These errors and deviations may affect each other and overlap each other, resulting in distortion and failure of research results, leading to wrong decisions and even serious losses. Therefore, the quality assurance of consumer research is very important, and various methods are needed to control and reduce errors and deviations and improve the accuracy and credibility of the research.

Quality Assurance Methods for 2. Consumer Research

The quality assurance method of consumer research can be carried out from the design of the survey, the collection of data, the analysis of the data and the presentation of the data, as follows:
