# Business Statistics and Research Methods MCQs for UGC NET and SET Exams 

By Statistics we mean aggregates of facts affected to a marked extent by multiplicity of causes, numerically expressed, enumerated or estimated according to a reasonable standards of accuracy, collected in a systematic manner for a predetermined purpose and placed in relation to each other.

Business statistics is simply the use of various statistical tools to business data.

Introduction to Research Methodology

Research methodology is a way to systematically solve the research problem. It may be understood as a science of studying how research is done scientifically. In it we study the various steps that are generally adopted by a researcher in studying his research problem along with the logic behind them.

In this post you will get Business Statistics and Research Methods MCQs which are especially for UGC NET and SET exams of various states such as SLET NE, GSET, WBSET. JKSET, Rajasthan SET, MP SET, MH SET, KSET and Kerala SET.

We try to cover all the questions asked in above mentioned exams relating to Business Statistics and Research Methods MCQs. Visit our website regularly for latest contents. ### Business Statistics and Research Methods MCQs for UGC NET and SET Exams
