Intro to Marketing Research: Qualitative Research - Focus Groups, Group Size Moderator Discussion Guide Advantages/Disadvantages Online Focus Groups

What It Is

A focus group is a qualitative research method that involves a small, diverse group of people discussing a specific topic or product in a controlled environment. This method is uniquely associated with the famous study conducted by Ernest Dichter, a renowned market researcher, who used focus groups to understand consumer attitudes towards cigarettes in the 1950s. Dichter's study led to significant changes in the marketing strategy of cigarette brands, highlighting the importance of understanding consumer behavior and attitudes. This matters for marketing decision-making as it helps businesses tailor their products and services to meet the needs and preferences of their target audience.

• Moderator: A trained researcher who facilitates the focus group discussion, ensures the discussion stays on track, and takes notes.
• Discussion Guide: A set of questions and topics that the moderator uses to guide the focus group discussion.
• Exploratory Research: A type of research that aims to generate new ideas and gain a deeper understanding of a topic or problem.
• Qualitative Research: A type of research that focuses on gathering non-numerical data, such as opinions, attitudes, and behaviors.
• Group Size: Typically 6-12 participants, although some studies use smaller or larger groups.
• Homogeneous Group: A group of people with similar characteristics, such as age, sex, or occupation.
• Heterogeneous Group: A group of people with diverse characteristics, such as age, sex, or occupation.
• Cronbach's Alpha: A statistical measure of the reliability of a scale or instrument.
• Validity: The extent to which a measure accurately measures what it is supposed to measure.
• Reliability: The extent to which a measure produces consistent results.
• Type I Error: The probability of rejecting a true null hypothesis.
• Type II Error: The probability of failing to reject a false null hypothesis.
• Sampling Bias: A type of bias that occurs when the sample is not representative of the population.
• Non-Probability Sampling: A type of sampling method where participants are selected based on convenience or availability.

Common Misunderstandings

• Misunderstanding: Focus groups are only used for exploratory research.
• Correction: Focus groups can be used for both exploratory and descriptive research, depending on the research objectives.
• Misunderstanding: Focus groups are only used for qualitative research.
• Correction: Focus groups can be used in conjunction with quantitative research methods, such as surveys or experiments.
