Study Notes

Types of Data

Discrete Data: fixed and whole numbers, easily visualized using statistical methods like bar graphs, line charts, histograms, and pie charts
Examples of Discrete Data: shoe sizes, number of blue cars sold
Characteristics of Discrete Data: fixed values, cannot have decimal points (e.g., cannot have a shoe size of 7.003)

Continuous Data

Occurs within a range of values
Examples of Continuous Data: height of a plant, weight of newborn kittens, temperature changes in a desert

Categorical Data

Data that is not measured, but categorized (e.g., pet choice, gender, hair color)
Characteristics of Categorical Data: no absolute difference among categories, cannot be measured or ordered

Data

A collection of information stored in digital format
Used as a base for performing analysis and decision making
Data science aims to organize data to make it easy to understand and use

Types of Data

Numerical Data: data that can be expressed numerically (real numbers, integers, floats)
- Discrete Data: fixed, whole numbers (e.g., shoe sizes)
- Continuous Data: occurs within a range of values (e.g., height of a plant)
Categorical Data: data that can be categorized (e.g., pet choice, gender)
- Nominal Data: data with no natural order (e.g., brand names, colors)
- Ordinal Data: data that can be ranked or ordered, but not measured (e.g., clothing sizes)
Image Data: composed of pixel values, used for tasks like object recognition and categorization
Text Data: consists of words and sentences
