-
May or may not be correct
-
Clear
-
Precise
-
Testable
-

Why Important?
-
Direction to research
-
Operationalize procedure
-
Select facts

-
Relation between variables
-
Provides a statement deduced from theory
Aims to Find?
-

Measuring Temperature for Hypothesis Testing
Null Hypothesis (H0)
-
No statistical significance between the two variables.
-
Researcher is trying to disprove it.
-
Individual is free from disease
-
Relationship is due to chance
Alternative Hypothesis (Ha)
-
Statistical significance between the two variables.
-
Researcher is trying to approve it
-
Individual has disease
-
Relationship is not due to chance
-
If is accepted, is rejected
Substantive vs. Statistical
-
Substantive – expected relation b/w variables, not operationalized
-
Statistical – operationalized in terms of statistical parameter
Simple vs. Complex
-
Simple – 1 IV & 1 DV
-
Complex – 2 or more IV & 2 or more DV
Practical vs. Statistical
-
Practical – In terms of practical outcomes
-
Statistical – In statistical outcomes
Positive, Negative or Null
-
Null – no relation b/w IV & DV
-
Positive
-
Negative
Universal vs. Existential
-
Universal – all variables are true at all times
“Brave soldiers if rewarded will perform well”
-
Existential – exist atleast for one particular case
“Few corporate staff might not perform well despite reward”
