  • 6. Data and method We have so much data, align to the required form. Apply statistical tools to turn data into information. Process is done for analysis and interpretation Unprocessed data does not help in decision making It helps in processing the raw data It is often in raw state It is operational technique It is quantitative STATISTICS AS METHOD STATISTICS AS DATA
