What is the first step in deciding which statistical technique to use?

The first step in deciding which statistical technique to use is recognizing the specific question that needs to be addressed. Clearly identifying the research question or objective is crucial as it dictates the overall direction of the analysis. This foundational understanding helps to ensure that the appropriate statistical methods are selected, which can vary widely depending on whether the focus is on comparing groups, analyzing trends, or examining relationships.

By defining the question, one can consider the context of the data, the type of analysis required, and the level of detail needed to answer it effectively. This initial step sets the stage for subsequent considerations, such as determining hypotheses, identifying relevant variables, and choosing appropriate measurement scales, all of which hinge on the clarity of the research question.
