On Independent Study - quasi-experiment
The basic idea underlying quasi-experiment , using an example, is as follows: Choose 2 companies of very similar profile: Step 1: Company A and Company B Step 2: choose 5-6 years of financial data of both companies Step 3: for one company, say Company A, a stimulus was introduced, e.g. implementation of ISO9000 by Company A in year 3; while Company B did not. Step 4: Try to evaluate whether implementation of ISO9000 improved the financial performance of Company A How: Method 1: graphic approach, e.g. line graph, as the following diagram illustrates: Method 2: store the panel data of Company A and B in one file and conduct a multiple regression analysis; use a flag to indicate whether ISO9000 has been implemented; 0 = not implemented while 1 = implemented. E.g. of file fields can be: (1) financial year; (2) Return of Equity; (3) implementation of ISO 9000; (4) Sales Turnover; (5) Gearing ratios)... etc You could improve your research design with a larger sample size...
