To ensure this we make the choice by means of a process in which chance alone operates, such as spinning a coin or, more usually, the use of a table of random numbers. An operational definition is A) a speculative statement about the relationship between two variables. In a study on the comparison of the performance of nationalized commercial banks (NCB) and private commercial banks (PCB) by Hasan (1995), one of the hypotheses was of the following form: The term more efficient was assessed by testing the statistical significance of the differences in the mean deposits of the two banks in question at a 5% level.
