Data preparation encompasses the process of transforming raw data into a format suitable for analysis in statistical software. It involves three main stages: editing, coding, and transcription.
Editing involves identifying and correcting errors in data entries, including typos, omissions, and inconsistencies. This ensures the accuracy and completeness of the data.
Coding involves assigning unique numbers or labels to data points, known as codes. This allows data to be organized and referenced efficiently. Examples of codes could be product identifiers, customer names, or research variables.
Transcription involves converting raw data into a format suitable for analysis. This may involve formatting dates, converting categorical variables into numerical data, or removing irrelevant information.
By properly preparing data, we can ensure its accuracy, consistency, and completeness, enabling us to achieve reliable and insightful results in our marketing research endeavors
