Study Notes
Statistics Overview
- Mathematics branch focusing on the scientific collection, organization, and interpretation of numerical data is statistics.
Types of Statistics
- Inferential statistics involves computations for prediction and making inferences about an entire population based on sample data.
Qualitative Data
- An example of qualitative data includes categories such as colors, gender, or types of cuisine.
Sample Representation
- A 'sample' in statistics represents a subset of a population used to make inferences about that population.
Population Characteristics
- Characteristics defining a given population are referred to as parameters.
Types of Information
- Quantitative information can be manipulated through fundamental operations like addition or subtraction.
Counting Variables
- A discrete variable is obtained by counting and can take on integer values.
Measurement Scales
- The interval scale of measurement arranges data in order and includes meaningful differences between values.
Ordinal Data
- Ordinal data reports ordering and ranking but does not establish the degree of variation between values.
Scale Characteristics
- The ratio scale features an arbitrary zero point, lacking a true zero, and can measure values meaningfully.
Grouping and Ranking Data
- Nominal data can be grouped, named, and ranked but lacks a true zero value, meaning it cannot measure the absence of a trait.
