In SPSS, when you open new file, in left bottom there is two tab: one is data view and another is variable view.

First in variable view, you have to enter what are all the variables you need for analyses, and also you can set the type of the data,width of the data,etc...,

(** note: no space between the variable name eg. you have to enter variable name as 'rainfall', not as 'rain fall')

After enter the variable name in variable view, the variables are automatically display in data view. You have to enter the corresponding variable data in data view.

If you want to change your variables or you have to add/delete any variables means, you have to do in variable view only not in data view.

After entering the data, you can start your analyses according to your wish.
