Study Notes
- The text discusses two types of data: quantitative and qualitative.
- Quantitative data is numerical data and can be further divided into discrete and continuous forms.
- Discrete data is based on counting whole numbers or zero, and cannot have numbers in between (e.g. eight cats).
- Continuous data is based on measurement and can have any number in between (e.g. distance between two points).
- Qualitative data is descriptive data based on observations and uses words to describe it (e.g. color, texture, taste).
- Examples of qualitative data include visual (color), tactile (soft or hard), auditory (volume), and olfactory (smell good or bad).
- To determine if data is quantitative or qualitative, if quantitative, determine if it's discrete or continuous based on counting or measurement.
Learn about the two types of data: quantitative (numerical data) and qualitative (descriptive data), and their subcategories such as discrete and continuous data. Understand the characteristics of each type and how to differentiate them.
