The  scientific  methods  is based on  certain  article of path  these are:
1.	Reliance on Evidence: Truth is established on  the basis  of evidence. Conclusion  is admitted only  when it is based  on evidence. Scientific methods involves a systematic  process. The answer  to a question  is not  decided by  intuition or  imagination. Relevant data are  collected through observation  or experimentation. The validity and the reliability of data are checked carefully  and the data  are analyzed  thoroughly  using  appropriate methods of analysis. Conclusion  is reached on the  basis of the  results of analysis.
2.	 Use of concepts: We experience a vast  number of facts  through our  senses. acts are things which actually exists. In order to deal  with  them  we use  concepts  with  specific  meanings. concepts  are logical  constructs or abstraction created from sense impressions percept s and  experiences. They are  symbols representing the meaning  that we  hold. We use them  in our thinking and communication. Otherwise  clarity and correct understanding cannot be achieved.
3.	Commitment to  Objectivity: Objectivity is the hallmark of the scientific method. It  means forming  a judgement  upon  facts unbiased by personal  impressions. According  to green objectivity is the  willingness and ability to examine evidence dispassionately. The conclusion should not vary from  person to person. It should be the same  for all persons. A person  of science must  above  all each individual  mind  as his own.
4.	 Ethical Neutrality: Science does not  pass normative judgement on facts,. It does not say that they  are good  or bad. As schroedniger says science never imposes anything science states  science aims at nothing  but making  true and adequate statements about its  objects.
5.	 Generalization: Scientists  are not concerned with isolated events  but with  the commonality of a series of event. They  aim at  discovering under the surface layer of diversity the  thread of uniformity. Around  a discovered uniformity a logical  class  and its  observed pattern a descriptive  generalization is formulated. In  formulating  a generalization  we should  avoid  the danger of  committing  the particularistic fallacy which a arises through an inclination to  generalize on  insufficient or incomplete and unrelated data. This can  be avoided by the accumulation of a large  body  of data  by the employment of comparisons  and control  groups.
6.	Verifiability: The conclusions arrived at by  a scientist should be verifiable. He must  make known to others how he arrived at his conclusions. He should thus expose his own methods and  conclusions to critical scrutiny. When  others test his conclusion under the same  condition then it is accepted as correct. Such verification through replication may  either confirm established  conclusions or modify  them or even invalidate them. For  example originally an atom  was  considered to be indivisible but subsequent researches have  proved  that it is  divisible and thus  provided the basis for developing  atomic  energy.
7.	Logical Reasoning  Process: The  scientific  methods involves  the logical  process of reasoning  this reasoning process is used for drawing inference from the finding of a study  or for arriving at  conclusion. For  example  in a survey of the expenditure pattern  on basic necessaries forms a very high proportion of the  total  expenditure  it is concluded that lower the household income the  higher is the proportion spent on basic  necessaries. The logical  reasoning  process consists of  induction and  deduction
