SCIENTIFIC METHOD

Example: A simple example will highlight, how a scientific method works. Let us assume that a researcher is conducting a market research project for a client manufacturing men's apparel. � Observation: Researcher observes that some of the competitors are doing a brisk business. Sales increase of apparel is mainly due to round or turtle neck shirt and narrow bottom pants. � Formulation of Hypothesis: Researcher now presumes that the product of his client is somewhat similar and the variation in shirt and pant variety as above is the main cause for competitors sales increase. � Future prediction: It is predicted that if his client introduces same / similar products, sales will increase. � Hypothesis testing: The client now produces, round neck shirts and narrow bottom pants for test marketing

PROCESS AND LOGIC IN SCIENTIFIC RESEARCH Observation: The researcher wants to observe, a set of important factors that is related to his problem. � Formulates Hypothesis: The researcher formulates hypothesis, which will explain Scientific Method in Research what he has observed � Future Prediction: The researcher draws a logical conclusion � Testing the hypothesis: Is the conclusion based on data �

you're faced with the problem of not being able to read because your pen torch doesn't work, and you're not happy about it. You think back to the last time your pen torch didn't work, and you remember that it was because of wornout batteries. You guess that worn-out batteries is the reason your pen torch isn't working now, so you get some new batteries from the drawer next to your bed and replace the ones in your pen torch. Oh! Your pen torch works. Identify a problem. Research the problem. Formulate a hypothesis. Conduct an experiment. Reach a conclusion.

Scientific method

CHARACTERISTICS OF SCIENTIFIC METHOD (a) Validity � (b) Reliability � Validity is the ability of a measuring instrument to measure what it is supposed to measure. A questionnaire is administered to find the attitudes of the respondent towards a movie. So long as the questionnaire serves this purpose, we say that the instrument is valid. � In physical science, instrument used such as barometer, thermometer or scale measures what it is intended to do. Also measurement can be repeated any number of times by different individuals, the result will be the same. �
