Week 4: DQ Reliability and validity 

Week 4: DQ Reliability and validity


Reliability and validity are difficult to achieve in organisation studies. Unlike processes that can be controlled within laboratories... humans can figure out they are being studied and shift results.

Once reliability and validity of an intervention has been established ... three conditions must be satisfied 

·         The cause has to occur in time before the effect.

·         Changes in the cause has to create a corresponding change in the effect.

·         No other explanation for the relationship can be present.

Do a google search and  define these key terms: 

Causality

Causal inference 

Reliability 

Validity

Why should OD practitioners be concerned with measures of validity,reliability,and causality?
