Factor analysis is a valuable technique for exploring data and finding the underlying structures important to a particular phenomenon. However, lots of texts tend to make factor analysis seem more complicated than it really is with mixed terminology such as eigenvalues, factors, latent roots and so on. Kline does not fall into this trap - his book is clear, concise and very useful. Examples clearly illustrate the principles of different styles of factor analysis and there is strong emphasis on interpretation which is the crucial element missing in so many other textbooks. I strongly recommend this book if you want to find out what factor analysis is all about but have struggled with other textbooks. It is only an introduction so is really only a good starting point but in this case that is one of its strengths.
