Lecture: Four research methods
1. Social science research methods & their links to business research
2. We consider:a. Historical methodb. Descriptive / correlational methodsc. Case study methodologiesd. Experimental methods

Historical researchUses in social science research
Uses in business research
Criteria to judge such researchObjectivity - SubjectivityInterpreation

Correlational research1. Most common type of field study.
2. Description is a starting place.
3. Correlational coefficient, r
4. Two dangers:1. Conceptual confusions
(tautologies)2. Causation claims

Correlational research1. Relationships between variables. There
are three possible results of a correlational study:
a. a positive correlationb. a negative correlation, and c. no correlation.
2. The correlation coefficient is a measure of correlation strength and can range from –1.00 to +1.00.

Correlational research
1.Bivariate data2.Types of correlational studies
(how, advantages & disadvantages)a. Naturalistic observationb. Survey methodsc. Archival research

Correlational research - Pearson’s r
An example follows:
Raw values (X, Y)Calculate means for raw Deviation scores (value less mean) (x,y)Multiply the deviation scoresSquare each of the deviation scoresAdd everything upCalculate mean for deviation products
