## What is cross loading in exploratory factor analysis?

When a variable is found to have more than one significant loading (depending on the sample size) it is termed a cross-loading, which makes it troublesome to label all the factors which are sharing the same variable and thus hard to make those factors be distinct and represent separate concepts.

## What are acceptable Communalities for factor analysis?

Communality value is also a deciding factor to include or exclude a variable in the factor analysis. A value of above 0.5 is considered to be ideal. But in a study, it is seen that a variable with low community value (<0.5), is contributing to a well defined factor, though loading is low.

**How do you interpret Communalities in factor analysis?**

Communalities indicate the amount of variance in each variable that is accounted for. Initial communalities are estimates of the variance in each variable accounted for by all components or factors. For principal components extraction, this is always equal to 1.0 for correlation analyses.

**How big are cross loadings in factor analysis?**

Even if you can justify ignoring <.5 with a citation, you seem to have cross loadings of .4-.5 with the “main” loading just .2 larger. I personally would feel very uncomfortable allocating such items to one factor.

### When to remov an exploratory factor analysis?

Items which load less than 0 .4 on any factor should be remov ed one at a time in reverse order of highest facto r loading. Cross factor loadings should then be considered using the cut-off rules described abov e. The number of factors can then be adjusted.

### How is exploratory factor analysis used in validation studies?

395 After more than one hundred years of development, Exploratory Factor Analysis (EFA) has become one of the most extensively employed techniques in validation studies of psychological tests. In this sphere, the main goal of EFA is to determine the minimum number of common factors required to adequately reproduce the item correlation matrix.

**Which is an example of a factor loading?**

A factor loading for a variable is a measure of how much the variable contributes to the factor; thus, high Figure 1.
