"The type of measure used placed constraints on which statistics can be used"

In this quote, Stanley Smith Stevens is talking about the effect of the type of measure utilized on the stats that can be used. Essentially, the kind of measure being used sets constraints on the types of statistics that can be applied. This is since different measures might require various statistical techniques or strategies to accurately evaluate the data. For instance, a continuous measure might require the use of connection or regression analysis, while a categorical measure might require using chi-square or ANOVA. For that reason, it is very important to carefully consider the kind of step being used in order to choose the suitable statistical method for precise and significant outcomes.
