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
