SCIENTIFIC APPROACH IN RESEARCH : 

SCIENTIFIC APPROACH IN RESEARCH Dr. Azadeh Asgari Research Methodology

Characteristics of Scientific Approach : 

Characteristics of Scientific Approach CONTROL Most important element in the scientific approach that allows scientists to identify the cause to what is being observed. E.g.: EXPERIMENT – To identify why an event happened (Which variable should the experimenter control?) OPERATIONAL DEFINITION All terms used must be defined operationally E.g.: Anxiety – Comparison between Stress and Anxiety – refers to the scores obtained in the Anxiety Scale Criterion Level

Characteristics of Scientific Approach : 

Characteristics of Scientific Approach REPLICATION Requires reliable data - i.e. Same results must be obtained if the research is repeated. HYPOTHESIS TESTING Researcher must systematically formulate the hypotheses and test them

Strengths of Scientific Approach : 

Strengths of Scientific Approach Main strengths in scientific approach are due to its CONTROL OF VARIABLES & PRECISION OF MEASUREMENT. Example: CONTROL: through proper sampling techniques and research design procedures PRECISION: use of reliable quantitative measurements

Strengths of Scientific Approach : 

Strengths of Scientific Approach Experiments points to clarification of cause-effect relationships Example: SYSTEMATIC CONTROL of a variable is observed to give effect on another variable, on condition that the other variables are controlled, kept constant or are being eliminated

Strengths of Scientific Approach : 

Strengths of Scientific Approach Utilization of HYPOTHESIS TESTING and QUANTITATIVE DATA allow statistical analyses be conducted, therefore, more precise.
