2.2 Rotated Factor Solution

Factor rotation is a crucial component in EFA. It is a technique used to simplify the factor structure by reorganizing the factors to enhance the interpretability of identified factors. There are two types of factor rotation: orthogonal and oblique rotation.

2.2.1 Orthogonal vs. oblique rotation

In orthogonal rotation, factors are considered to be uncorrelated, which means that there is no correlation between any two factors. Varimax and equimax are two examples of orthogonal rotation. Among these, the varimax rotation is commonly used by researchers.

2.2.2 Oblique rotation

Unlike orthogonal rotation, oblique rotation allows factors to be correlated suggesting that factors in real-life are not entirely independent. Examples of oblique rotation are promax, Promax, oblimin.
