Quantitative data analysis requires the construction of two types of measures of variables--indices and scales these measures are frequently used and are important. An operational definition is how we (the researcher) decide to measure our the variables in our study research method used to observe and describe. This control may involve manipulating existing variables (eg, modifying existing methods of instruction) or introducing new variables in the research setting.
