Scatterplot can be obtained by selecting Graph--->Plot from the menu. In the dialog box, Gas and Degree-days are selected as the y and x variables, respectively.
Scatterplot
When we are interested in the
relationeship between two quantitative varibles, we usually use
a scatterplot to display such relationship. Here, we use the data
in table 2.1 in BPS to illustrate the relationeship between outside
temperatures and the consumption of gas. The data are also stored
in TA02-01.MTW
Scatterplot
can be obtained by selecting Graph--->Plot from the
menu. In the dialog box, Gas and Degree-days are selected as the
y and x variables, respectively.
Use
following session command to obtain the same scatterplot. MTB>plot
'Gas' * 'Degree-days'
This command
give us a scatterplot with "Degree-days " as the explanatory
or x variable and "Gas consumption" as the response
or y variable. The scatterplot shows a strong linear relationship.
