Structured Data
Definition: Structured data refers to information that is organized in a predefined and systematic way. It typically fits neatly into tables or relational databases with rows and columns.Characteristics: Each data element has a clear and well-defined format.Examples: Excel spreadsheets, relational databases, CSV files, tables.
Quantitative data
Definition: Quantitative data refers to information that is numeric and can be measured and expressed with numerical values. It involves quantities and is suitable for mathematical and statistical analysis.Characteristics: Quantitative data is often collected through methods such as surveys, experiments, or measurements. It allows for quantitative comparisons and statistical analysis. Examples: Height and weight measurements, survey responses on a numerical scale.
Unstructured Data
Definition: Unstructured data refers to information that does not have a predefined data model or is not organized in a structured manner.Characteristics: This type of data does not fit neatly into traditional relational databases with rows and columns. Unstructured data can be diverse and may include text, images, audio, video, social media posts, emails, and more.Examples: Text documents, images, audio recordings, video files, emails, social media posts.
Qualitative data
Definition: Qualitative data refers to non-numeric information that provides insights into qualities, attributes, or characteristics. It focuses on understanding the underlying meanings, patterns, and contexts.Characteristics: Qualitative data often involves subjective interpretation and may be collected through methods such as interviews, focus groups, observations, or open-ended surveys. It can include textual information, images, audio, or video, and the emphasis is on capturing the richness and complexity of human experiences.Examples: Interview transcripts, open-ended survey responses, field notes, images, audio recordings.
