n the analysis of enumeration data, the researcher often needs to decide whether several independent samples should be regarded as having come from the somewhat, and the problem is to be determine whether the observe samples from the same population
Enumeration
data are expressed in the form of frequencies, which represent the number of
items within specified qualities, descriptions, or categories.
Enumeration
data may be classified according to the number of variables described as either
one-way or two-way classification. Each variable is further subdivided into
more specific categories.
A one-way
classification has only one variable described by at least two categories. Let
us take, for instance, the variable on civil status. Civil status may be subdivided
into more specific categories – single, married, widowed, married but legally
separated.
Two-way classification
enumeration data have two variables described by their respective categories.
The frequencies given are applicable to both variables. Data with two-way
classification are best summarized and presented in a contigencu table which is
made up of several rows and columns, the rows representing the categories of
the one variable, and the columns representing the categories of the other
variable.
