Cleaning data involves

Question

BlackTom AI · Accepted Answer

To begin, let's restate the question and the choices in plain terms so we can compare what each option implies about cleaning data.
Option a: 'editing, formatting or deleting data in a data set.' This captures the core activities of data cleaning, which include correcting errors, standardizing formats, and removing unnecessary or erroneous records to improve data quality.
Option b: 'embedding a HTML snippet into a web page.' Embedding HTML is a web development task, not a data cleaning activity; it relates to presentation rather than ensuring data accuracy or consistency.
Option c: 'getting data from the data source.' This describes data collection or data sourcing, not the cleaning process. Cleaning happens after data has been gathered, not during the initial retrieval step.
Option d: 'manipulating data into a visualisation.' Creating visualizations is an analysis or presentation step; while it may involve cleaned data, the action described is not cleaning itself but the downstream use of data.
Expanding on Option a, the terms 'editing', 'formatting', and 'deleting' directly map onto typical cleaning operations: correcting typos or inconsistencies (editing), standardizing units, date formats, or categorical labels (formatting), and removing duplicates or invalid rows (deleting). These actions collectively improve data reliability for analysis.
Considering the other options, each describes a different phase or outcome (web content, data collection, or visualization) rather than the actual purification of data. Thus, option a aligns with the conventional definition of data cleaning, while options b, c, and d point to activities outside cleaning duties or at a different stage in the data workflow.
