Study Notes
Data Distributions
- Variables: Measurable or observable sources of data (e.g., temperature, mass, car make). Usually change between observations.
-
Data Types:
-
Numerical (Quantitative): Data points represented by numbers.
- Discrete: Distinct, separate values, often whole numbers (e.g., number of goals, children per family). Gaps exist between data points. Shoe sizes are an example (even though they aren't whole numbers).
- Continuous: Data points can exist anywhere along a continuum (e.g., height, time, temperature). Values are often decimal numbers. Accuracy limited by the measuring device.
-
Categorical (Qualitative): Data points represented by words or labels.
- Ordinal: Categories can be ordered or ranked (e.g., product ratings, exam grades, fish size).
- Nominal: Categories have no inherent order (e.g., nationalities, car makes, hair color).
-
Numerical (Quantitative): Data points represented by numbers.
Levels of Measurement
-
Nominal: Categories with no natural order. (e.g., employment status, blood type). Can only determine frequency and mode.
-
Ordinal: Categories with a natural order. (e.g., customer satisfaction ratings, exam grades) Allows frequency, mode and the calculation of the median through assignment of numbers to outcome categories but interpretations can be debated
-
Interval: Numerical scale with equal intervals between values. Lacks a true zero. (e.g., temperature in Celsius, pH scale, dates). Allows frequency, mode, mean, and median. The difference between two values can be interpreted but ratios cannot.
-
Ratio: Numerical scale with equal intervals and a true zero. (e.g., temperature in Kelvin, weight, speed). Allows frequency, mode, mean, median and ratios of values in addition to differences can be calculated.
-
A true zero means the absence of the quantity being measured.
