Regression analysis plays a vital role in contemporary market research, offering a powerful tool for making accurate forecasts and addressing intricate interdependencies within challenges and decisions. It enables us to predict user behavior and gain valuable insights for optimising business strategies. This article aims to elucidate the concept of regression analysis, delve into its working principles, and explore its applications in the field of market research.
Regression analysis serves as a statistical method and acts as a translator within the realm of market research, enabling the conversion of ambiguous or complex data into concise and understandable information.
By investigating the relationship between two or more variables, regression analysis sheds light on crucial interactions, such as the correlation between user behavior and screen time in smartphone applications.
Regression analysis serves multiple purposes.
Regression analysis traces its roots back to the late 19th century when it was pioneered by the renowned British statistician, Sir Francis Galton. Galton explored variables within human genetics and introduced the concept of regression.
By examining the relationship between parental height and the height of their offspring, Galton laid the foundation for linear regression analysis. Since then, this methodology has found extensive applications not only in market research but also in diverse fields such as psychology, sociology, medicine, and economics.

Regression analysis encompasses various regression models, each serving specific purposes depending on the research objectives and data availability.
Employing a combination of these techniques allows for in-depth insights into complex phenomena. Here are the key regression models:
The classic model examines the relationship between a dependent variable and a single independent variable, revealing their association. For instance, it can explore how daily coffee consumption (independent variable) impacts daily energy levels (dependent variable).
Expanding upon simple linear regression, this model incorporates multiple independent variables, such as price, advertising, competition, or sales figures. In the context of energy levels, variables like sleep duration and exercise can be added alongside coffee consumption.
When the relationship between variables deviates from a straight line, non-linear regression comes into play. This is particularly useful for phenomena like exponential growth in app downloads or user numbers, where traditional linear models may not be suitable.
For complex correlations or patterns characterised by ups and downs, quadratic regression is utilised.
It fits data that follows non-linear trends, such as seasonal sales fluctuations. For instance, it can help determine market saturation points, where growth typically plateaus after an initial rapid expansion.
Hierarchical regression allows the researcher to control the order of variables in a model, enabling the assessment of each independent variable's contribution to predicting the dependent variable.
For example, in demographic-based analyses, variables like age, gender or education levels may be weighted differently.
This model examines the probabilities of outcomes with more than two variables, making it valuable for complex questions.
For instance, a music app may predict users' favourite genres based on their previous preferences, listening habits, and other factors like age, gender, or listening time, enabling personalised recommendations.
When multiple dependent variables and their interactions with independent variables need to be explored, multivariate regression analysis is employed.
For instance, in the context of fitness data, it can assess how factors such as diet, sleep, or exercise intensity influence variables like weight and health status.
This model comes into play when a variable has only two possible answers, such as yes or no. Binary logistic regression can be utilised to predict whether a specific product will be purchased by a target group. Factors like age, income, or gender can further segment the buyer groups.
The versatility of regression analysis is reflected in its diverse applications within the field of market research. Here are selected examples of how regression analysis is utilised:
Suppose a company aims to determine the relationship between advertising spending and product sales, requiring a simple linear regression analysis. Here are five possible steps to conduct this analysis:
Regression analysis stands as a powerful and versatile tool in the realm of market research. It offers a range of regression models, varying in complexity depending on the research question or objective at hand. Whether investigating the relationship between advertising spend and sales, analysing usage behavior, or identifying market trends, regression analysis provides data-driven insights that empower informed and sound decision-making.
