Introduction
Factor analysis is particularly a technique or method, used with SPSS help, is generally used for conducting a process of reduction of a huge number of different variables which is then turned out into very little in the number of factors. The factor analysis technique specially conducts a process of extraction of all of the maximum common variances from the group of all the included variables and then further puts them into an analysis procedure of the common score. Factor analysis allows the user to conduct a process of simplifying a particular set of few complex variables or things through the application of statistical procedures in it for exploring all the underlying dimensions present in that group later which will explain the relationships among all the multiple variables/things. There is quite a connected relationship between psychology and factor analysis since the factor analysis technique has lots of applications in the psychological aspects and analysis of variable groups.
What is a Factor Analysis? All about psychology
The factor analysis statistical method mainly works for reducing the variables from the group or set of them all by extracting all the similarities and common matches in them which are then divided into a smaller number of groups of factors. This whole procedure is known by the name of data reduction through the factor analysis technique. In simple language, the prime activity of the factor analysis is to minimise or reduce the huge number of variables into smaller or fewer amounts of factors through the method of extraction finding out the common variances and gathering all of them into a platform of the common score of those numbers. The factor analysis technique is also a huge portion of the prime General Linear Model (GLM), so this factor analysis method primarily assumes various types of assumptions. These standard assumptions are such as - the linear relationship, and the no multi-collinearity. Further, it also includes all the variables that are relevant to a process of analysis, and lastly, there exist all the very true correlations among the factors and variables. There are a lot of SPSS data analysis techniques or methods available for factor extraction of a huge group of numbers to reduce them into smaller numbers, but the principal component of analysis that is applied mostly and commonly is the factor analysis.
Psychology is basically the scientific type of study related to the mind and behaviour of people around by studying them and their mental state. Psychologists are such people who are actively and confidently engaged in studying, analysing, and understanding the pattern of mental processing, brain functioning, attitude changing, and behavioural instincts of people in society. Psychology is a segment of the topic of the subject Behavioural Neuroscience, where the stream of psychology includes all such factors which influence the plasticity element of the human brain, thinking process, and behaviour with the help of the development of their brain and sneaking into their whole adulthood. The psychological aspect of human nature consists of factors like their physical hippocampal biology and its functioning, stress, and other things of the brain. The psychological section has its own sub-sections listed as – clinical psychology, cognitive psychology, decision science, development psychology, intellectual and developmental disabilities, quantitative psychology, and lastly social psychology. Clinical psychology is regarding the overall treatment of human mood, mentality, and personality disorders too by utilising different cognitive behavioural based therapies. Cognitive psychology is about experimental activities, brain imaging, and other things through various types of models or approaches to clearly depict human perception, memory power, decision-making ability, human actions, and lastly the body language of people. The next is decision science, the process of analysing the effects of judgments and choices through the affective, social, and cognitive aspects. Further, developmental psychology is related to the process of learning and the developmental impacts of the behavioural and cognitive changes of the human brain. The next is the intellectual and developmental disabilities segment where improvement of the overall health and well-being of the aged people, adults, teenage people, and children about their autism spectrum issues, intellectual disabilities, and other relevant neuro-developmental disorders in society. The next in this list is quantitative psychology where there is the study of psychological data through the application of varied statistical models for evaluating that set of data by applying the quantitative analysis method. The last segment is social psychology presents the influences of the processing, judging, and behavioural results from the deliberative and automatic attitudes of the people.
The factor analysis and the psychology field have an inter-relative nature in both of them because factor analysis is a multivariate analysis statistical method for reducing a large amount of data into smaller numbers. Since psychology is also a subject with huge data collection and numbers, here factor analysis can also be used in the case of evaluating and calculating the gathered data and ten reduce them into fewer number groups or variances. In the factor analysis process, there are lots of variables included so that they can be reduced to a lesser number of latent variables or into groups with different characteristics. When the factor analysis is applied to the psychological analysis, it uses both the confirmative and explorative types of studies so that the results can be achieved. Here the principle components and groups' behavioural traits are studied, evaluated, analysed, and tested in different groups of populations along with the independent set of variables to present the latent and linear variable combinations.
