- 1.1: Statistics Vocabulary
- The mathematical theory of statistics is easier to learn when you know the language. This module presents important terms that will be used throughout the text.
- 1.2: Sampling Techniques
- Data are individual items of information that come from a population or sample. Data may be classified as qualitative, quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample.
