PSYC 2030 Lecture Notes - Lecture 2: Descriptive Statistics, Statistical Inference, Bar Chart
Document Summary
Data set a specified body of numerical information obtained from a given piece of research. Descriptive statistics numerical statements about the properties of some data. Inferential statistics numerical statements that represent conclusions about populations on the basis of a sample data. Statistics numerical statements about data from a sample, and the scientific discipline associated with making and understanding those statements. Nominal measures simply identify the category or class of events to which particular response belongs. Nominal variables describe people and their behaviour in terms of their categories; male or female, young or old. Ordinal measures place responses on a single measurement continuum where different values indicate the relative magnitude of a particular response. Interval measures where there is a specific and constant quantitative relationship between the various outcomes that are measured. Scores or responses obtained correspond to an equal quantity of the measured variable. Ratio measures clearly specify a zero point.
