Appendix (p590-601) Hypothesis a formal statement of the expected relationship between two variables.

Measurement of Variables Reliability is a index of the consistency of a research subjects responses. (e.g. if we ask someone several questions about how his pay is, he should respond roughly the same way to each question) Validity is an index of the extent to which a measure truly reflects what it is suppose to measure. (e.g. a good measure of perceived pay fairness should not be influenced by employees feelings of fairness about other workplace factors like supervisision) Convergent validity when there is a strong relationship between different measures of the same variable. (e.g. a measure of job satisfaction should be highly correlated to other measures of job satisfaction) Discriminant validity when there is a weak relationship between measures of different variables. (e.g. a measure of job satisfaction should not be strongly related to measures of job performance) Observational Techniques Observational research-research that examines the natural activities of people in an organizational setting by listening to what they say and watching what they do Most straightforward way of finding out about OB 1
