statistical procedure to estimate the liner dependency of one or more independent variables on dependent variables. Confidence that the true (population) relation between X and Y lies between “Lower” and “Upper” Methodology * Form a theoretical model of the relationship under consideration. * This model suggests what explanatory variables to include in the analysis. * Collect data on independent and dependent variables. * Estimate regression line. * Examine results. This includes

statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates

analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates the conditional expectation of the dependent variable given the independent variables — that is, the

on an independent variable and we want to test hypotheses about differences on one or more dependent variables OR • We have two groups which already differ on a dependent variable and we want to test hypotheses about differences on one or more independent variables ADVANTAGES OF EXPOST FACTO Since most of the social behavioural problems, cannot be subjected to experimental investigations, ex-post factor research is a good explanatory instrument of changes that take place in the dependent variables

Experiments are mainly used to discover scientific laws of cause and effect within individuals. Experiments normally take place within a laboratory environment or an artificial experiment, therefore allowing scientists to control all the different variables to see what effect they may have whether it is positive or negative. Scientific methods tend to involve an experimental group or a control group, they then compare the results from the two groups to try and discover cause and effect relationship

span of about 50 years (1963-2010) with childhood obesity being the dependent variable influenced by the independent variables of age, family median household income, and gender, which will show the correlation to childhood obesity. There were eleven samples of years used in the analysis. The years were inclusive of two or more so an average of the years was used for the data in the eleven observations. The most important variable in this research is how the parent’s income level has been a factor

Executive Summary Multivariate data is a key part of any interaction in business. The data can be used to anticipate the effect of several variables. Multivariate relationships involve multiple independent variables affecting a dependent variable. These independent variables have a distinct and measurable effect on the dependent variable. These relationships can be used by managers to make decisions. The example given is that of an automobile manufacturer that uses the data to change the
