First, we have to run AMOS. By clicking the “start” menu and selecting the “AMOS graphic” option, we can run the program. The moment AMOS starts running, a window appears called the “AMOS graphic.” In this window, we can manually draw our SEM model.
Attaching Data: By selecting a file name of the data file option, we can attach data in AMOS for SEM analysis. This option also appears if we will click on the “select data” icon.
Observed Variable: A rectangle icon is used to draw the observed variable.
Unobserved Variable: A circle icon is used to draw the unobserved variable.
Cause Effect Relationship: A single headed arrow in AMOS is used to draw the cause-effect relationship between the observed and unobserved variables.
Covariance: A double-headed arrow is used to draw the covariance between variables.
Error Term: In AMOS, the error term icon is next to the unobserved variable icon, and it is used to draw the latent variable.
Naming the Variable: When we right click on a variable in a graphical window, the first option, “object properties,” is used to give the name of the variable in AMOS.
There are other icons as well, and these icons help in drawing the SEM model graphical. Icons such as erase icon, moving icon, calculate icon, view text, analysis properties, etc., help in drawing the SEM model graphs.
