Bivariate analysis is concerned with the relationships between pairs of variables
(X, Y) in a data set. Bivariate analysis, explores the concept of association between two
variables. The association is based on how two variables simultaneously change together,
that is, the notion of co-variation.
Bivariate analysis is the simultaneous analysis of two variables. It is usually undertaken
to see if one variable is related to another variable. Multivariate analysis is the
simultaneous analysis of three or more variables. It is frequently done to refine a
bivariate analysis, taking into account the possible influence of a third variable on the
original bivariate relationship. Multivariate analysis is also used to test the joint
effects of two or more variables upon a dependent variable.
Using bivariate analysis we test hypotheses of "association" and causality.
Association refers to the extent to which it becomes easier to know/predict a value for
the Dependent variable if we know a case's value on the independent variable.
To begin the bivariate analysis, the first step is to construct a scattergram to
illustrate the relationship. Each dot represents a paired value from the sample, and the
scattergram reveals a typical oval shape that is due to central tendency (Sprinthall
1990,200).
Bivariate analysis helps compare and control two or more related variables in situations
where quality depends on the combine effect of these variables. This method is most useful
when two different variables work together to affect the acceptability of a process or
part thereof.
The bivariate analysis should be useful in supporting or failing to support the arguments
of dependency theorists that there is an association between dependency and
underdevelopment - The question of dependency and economic development: a quantitative
analysis By Brian R. Farmer
Univariate Analysis describes the pattern of response to the variable and
describes each variable on its own. Univariate descriptive statistics can summarize large
quantities of numerical data and reveal patterns in the raw data.
Multivariate analysis is a form of quantitative
analysis which examines three or more variables at the same time, in order to
understand the relationships among them.
Univariate analysis is a form of quantitative analysis of data where each variable
is analyzed in isolation.
