Hello everyone....
Graphs
There are many types of graphs, and under this
category we have studied cross tabs but while reading about it I came across an
article which said that cross tabs and scatter plot are closely associated with
each other.
Cross tab and Scatter plot
Cross tabs helps us establish a relationship between
two variables. This relationship is exhibited in tabular form.
Scatter plots
(also known as Scatter diagrams or graphs) are used to analyze the relationship
between two variables. It shows how much one variable affects the other
variable. This relationship between the two variables is termed as correlation.
How scatter
plots differ from crosstabs under the graph menu?
Cross tabs are
designed for discrete variables, whereas scatterplots are designed for continuous
variables.
On comparing
the diagrams of a cross tab and a scatter plot, the following differences are
observed: -
- · In a scatter plot, the graph represents hundreds of cases that are represented by the dots but we can’t interpret what data is present behind each dot. Hence it becomes difficult to do further analysis of the data.
- · Crosstabs present the data in tabular form, with independent variables across the top and dependent variables along the side, and the data is even represented in the percentage form, which leverages the analysis of the data.
However, there
are limitations of crosstabs. Crosstabs tables cannot handle more than 7
categories in the column variable without “wrapping” over. This would result in
the tables with more than 10 categories for the independent variable
"wrapped around" and printed as a "continuation" of the
first table.
