Preliminaries

• Research techniques
• Population, sample, representativeness
• Sampling techniques

Variables

• Quantitative vs. qualitative
• Independent (factors) vs. dependent
• Nominal vs. quantitative scales
• Ratio (zero point, equal distances), interval (no zero point, equal distances), ordinal scales (no zero point, unequal distances)
• Continuous vs. discrete scales

Parameters

• correlation

Presenting Statistical Data

• tables
• graphs

Working Statistical Programs

• coding data
• importing data
• performing analyses
• tabulating results

Examples
