Data Types:

Objective: Facts and verifiable → Based on measurements of a subjects response

→ free from researcher bias as the info can be veridied by researcher

→ less detailed data

Subjective: Opinionated → determined by the subjects opinions

→ May be biased data as opinions cannot be verified

→ complex and rich in data

Qualitative: Words and pictures Provides informations about the waualities or characteristsics of whats being studied

→ rich, deep, detail in info

Quantitative: Numbers

Objective Quantitative: Factual numerical

Subjective Quantitative: Opinionated numerical
