Susan's measure is designed to measure three distinct concepts. Previous research demonstrated that each of these distinct subscales exists within the measure Susan is using. What statistical test would have been conducted to ensure the three subscales really exist?
A)factor analysis
B)isomorphic statistic
C)interval statistic
D)descriptive statistic

Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. It is commonly used to identify the underlying structure (such as subscales) within a set of variables or items in a measure, making it the appropriate test for confirming the existence of three distinct subscales in Susan's measure.
