Direction to research Operationalize procedure Select facts Replicate research Draw logical conclusion Relation between variables Provides a statement deduced from theory Aims to Find? Difference Relationship (Statistically significant – Implies difference in result did not occur by chance) Interaction Null versus Alternative Hypothesis Null Hypothesis (𝐻_0) 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 (𝐻_𝑎) Statistical significance between the two variables. Researcher is trying to approve it  Individual has disease Relationship is not due to chance If 𝐻_𝑎 is accepted, 𝐻_0 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” Chapters: 0:00 Introduction: What is Hypothesis?
