BUS 300 Lecture Notes - Lecture 7: Dependent And Independent Variables, Design Issues, Hawthorne Effect
Document Summary
How it all occurs is vitally important to it directors. Researchers designed a laboratory experiment to compare performance of two electronic protocols (fix and soap) The sampling units for an experiment, usually human respondents who provide measures based on the experimental manipulation. Experimental conditions: one of the possible levels of an experimental (independent) variable manipulation. Blocking variables: variables included in the statistical analysis as a way of controlling or accounting for variance due to that variable, categorical variables. The experimental difference in dependent variable means between the different levels of any single experimental variable. Differences in dependent variable means due to a specific combination of independent variables. Experimental treatment: the way an experimental variable is manipulated: categorical variables: described by class or quality, continuous variables: described by quantity (level) Experimental group: a group of subjects to whom an experimental treatment is administered. Control group: a group of subjects to whom no experimental treatment is administered.
