A team exports a spreadsheet where each row lists a customer and each column contains attributes such as age, subscription type, and churn status. When preparing this dataset for a machine learning model, which data type does it represent?
Time-series data
Image data
Tabular data
Unstructured text data
Data arranged in rows and columns like a spreadsheet is considered tabular data. Each row is an independent record and each column is a feature, which is the typical structure used by algorithms such as linear regression or decision trees. Unstructured text, time-series, and image data have different formats: text is free-form strings, time-series emphasizes sequence and timestamp order, and image data consists of pixel arrays. Therefore, only the tabular option correctly describes the customer spreadsheet.
