What is hypothesis

Hypothesis: A prediction of the outcome of a study. Hypotheses are drawn from theories and research questions or from direct observations. In fact, a research problem can be formulated as a hypothesis. To test the hypothesis we need to formulate it in terms that can actually be analysed with statistical tools.

As an example, if we want to explore whether using a specific teaching method at school will result in better school marks (research question), the hypothesis could be that the mean school marks of students being taught with that specific teaching method will be higher than of those being taught using other methods. In this example, we stated a hypothesis about the expected differences between groups. Other hypotheses may refer to correlations between variables.

A hypothesis should include a statement about the relationship between two or more variables and carry clear implications for testing the stated relationship. For example, you might need to know if and how your customers’ positive and negative product expectations are confirmed or disconfirmed upon product use.

How to Formulate the Research Problem

Problem formulation is simplified once we define the components of the research problem.

Specify the Research Objectives: A clear statement of objectives will help you develop effective research. It will help the decision makers evaluate your project. It is critical that you have manageable objectives. Thus, two or three clear goals will help to keep your research project focused and relevant.
Review the Environment or Context of the Problem: As a marketing researcher, you must work closely with your team. This will help you determine whether the findings of your project will produce enough information to be worth the cost. In order to do this, you have to identify the environmental variables that will affect the research project. These variables will be discussed in-depth in later units.
Explore the Nature of the Problem: Research problems range from simple to complex, depending on the number of variables and the nature of their relationship. If you understand the nature of the problem as a researcher, you will be able to better develop a solution for the problem. To help you understand all dimensions, you might want to consider focus groups of consumers, sales people, managers, or professionals to provide what is sometimes much needed insight.
Define the Variable Relationships: Marketing plans often focus on creating a sequence of behaviours that occur over time, as in the adoption of a new package design, or the introduction of a new product. Such programmes create a commitment to follow some behavioural pattern in the future. Studying such a process involves:

Determining which variables affect the solution to the problem.
Determining the degree to which each variable can be controlled.
Determining the functional relationships between the variables and which variables are critical to the solution of the problem.
During the problem formulation stage, you will want to generate and consider as many courses of action and
