In this video I will demonstrate the performance of factor analysis now before we get into the actual demonstration of the techniques I want to talk a little bit about the theory and some of the application behind when and why we would use factor analysis now this technique is very different than many of the techniques we use in inferential statistics when we're basically trying to compare groups to look for differences or even when we're doing correlations or regression when we're trying to make predictions or find relationships among variables factor analysis is really more of a data reduction technique it takes a large potentially large set of variables and looks for a way that the data can be reduced or kind of summarized using a smaller set of variables or components now it does this by looking for clumps or groups that have very strong intro correlations within a set of variables so this is very difficult to do by eye you know we can look for correlations in a correlation matrix when we've got small number of variables but when we have a large number of variables which can very often be the case in factor analysis we might have 10 15 20 or even 30 or more variables that we're trying to kind of find inter correlations and try and find a pattern to how these variables work together so that's difficult to do by eye so this technique helps us do that mathematically so factor analysis techniques have a lot of different uses it's used a lot by researchers especially when we're trying to develop and evaluate tests or scales that measure a particular construct or a particular knowledge area how this typically works is the person developing the scale starts with a large number of individual items or questions on a on a scale or a measurement tool and then by using these analytic techniques and factor analysis we can kind of refine and reduce these items into a smaller number of sub scales that measure the construct together but also maybe measure various aspects of that construct so we can use factor analysis to reduce a large number of related variables to a more manageable number and also a more efficient number of variables to measure our constructs so we don't have redundancy in the measurement of a construct but we're measuring all aspects of that construct so there's kind of two main approaches to factor analysis that you'll typically see described one is called exploratory and the other is called confirmatory now exploratory factor analysis is used typically in early stages of research in which we're trying to develop a theory or to gather information about relationships among variables when we do confirmatory analysis what we're doing is we're actually trying to confirm or test specific hypotheses or theories that we've developed concerning the structure or the construct underlying a set of variables now confirmatory factor analysis is a lot more complex and very sophisticated but it helps us helps us confirm theories and helps us get a...
