Science can also be defined as a systematic knowledge based on either observation or experiment or study and lays down certain principles about the subject, which is observed, experimented or studied. If this be the definition of science, then Economics is a science, because this knowledge is a systematic knowledge. It is based on observation and study. It lays down certain principles or laws.
