Data collection can face various challenges such as non-response bias (when participants refuse to participate or fail to respond), sampling bias (when the selected sample does not represent the entire population), data quality issues (incomplete or inaccurate data), logistical issues (time constraints, resources, or access to participants), and ethical considerations (privacy, informed consent, or confidentiality). These challenges need to be carefully addressed to ensure the validity and reliability of the collected data.
