On using factor analysis to explain concepts, tests, proficiency tests and datasets when we are here; Using the common used factor analysis, and we are either exploratory and/or confirmatory when doing what we are doing!
Factor analysis has especially been used in the intelligence research. And the pioneers in this field is the British guy Charles Spearman, and the American guy Louis Leon Thurstone, and they developed the factor analysis to discover and to find the structure and the composition of the intelligence as the intelligence is being defined and explored and described and made analysis of when we are here as we are.
Factor analysis has been applied on other areas as the intelligence research within the psychology, for example to find sets and datasets with more fundaments and founding and basic personality traits from an individual's reply on personality tests. Prominent representatives for this application are Hans Jürgen Eysenck and Raymond Bernard Cattell, and we can use these concepts and measurements when we are where we are, and when we want to examine and investigate and explore and explain how things really are as they are.
Today, factor analysis is much used, especially in the analysis of tests. A test consists of several test sections, of multiple aspects, where we can use multiple traits and multiple methods when we are as we are. And the test sections are questions or statements that the person should reflect on, and the factor analysis is doing it possible to assess whether the answers that people are giving on the different test sections in the test, can be explained from one, two or several more than two underlying factors, when trying to explain much of what is happening in daily affairs and in the research life when we are here and there.
Factor analysis is a commonly used data reduction statistical technique within the context of market research. The goal of factor analysis is to discover relationships between variables within a dataset by looking at correlations. We have two kinds of factor analysis; Exploratory factor analysis when we are not sure about all the variables and the factors, and confirmatory factor analysis when we know what is being guessed through the literature, the courses in the sciences, and the daily chatting and talking about people when trying to discover and find the datasets for concepts that we have when being here, and concepts are either convergent or divergent, and we can find any latent structure on the human mind on any human, researcher and scientist when we are here where we are.
Exploratory factor analysis can be implemented with data as the starting point, often related to little that we know, for instance when we are unsure about what the theory really is, and it can be seen and considered as a method that one can use to simplify the data. A researcher can for instance investigate different answers on statements connected to behavior in the traffic, and one can find that the answeres are coming in groups in the factors like speed, being conscious in the traffic, and technical focus when we are in the markets that is often into ourselves as humans, since the markets consists of buyers and sellers, and these are individuals with needs, unless we cannot put people by being as robots when we are here. So, when using exploratory factor analysis there are much uncertainty about the processes and outcomes with the concepts, methods and data when we are here, but we are selecting something when doing research, and we can focus på sensible or stupid things when we are here where we are.
Confirmatory factor analysis is implemented with theory or determined expectations as starting point, and we are investigating whether an expected stucture in the data is there as it is. The Swedish statistician Karl Gustav Jöreskog, and he is born in 1935. And he has given important contributions to this method. And in the example mentioned above, one could with this method test directly whether there are such replies on statements of the behavior in the traffic while we are here as we are. And Karl Gustav Jöreskog is professor emeritus, and he has his education and research from Uppsala University in Sweden, and we should be intelligent and wise and clever to be best from that school! But anything is possible unless it is defined as impossible!
