When data are collected, each piece of information is tied to a particular case.
#Spss 16 limit of number of variables how to
Now that you know how to enter data, it is important to discuss a special type of variable called an ID variable. If we do not include ALL, SPSS will throw out any variables not named in the /KEEP statement.
#Spss 16 limit of number of variables code
The ALL option can only be used at the end of the line the code will fail if you try to put it before other variable names. The ALL option at the end of the line says to retain all remaining variables in their current order. The /KEEP statement tells SPSS the specific order of the variables you want: we list the variables by name, in the order we want, separated by spaces, on the right side of the equals sign. In the MATCH FILES command, FILE=* says to act on the the current active dataset. *Reorder the variables to place the new variable in the desired position.*/ We can use this syntax to perform these tasks: /*Compute new variable containing blanks (system-missing values).*/ Suppose we want to insert a new column of blank values into the sample dataset after the first variable, ids. You'll then use the MATCH FILES command to actually re-order the variables. You'll first use the COMPUTE command to initialize the new variable. Instead, you'll need to use two syntax commands. Is it possible to insert a variable using syntax? Technically, there's no direct syntax command to do so. You can enter values for the new variable by clicking the cells in the column and typing the values associated with each case (row). You should also define the variable's other properties (type, label, values, etc.) at this time.Īll values for the newly created variable will be missing (indicated by a “.” in each cell in Data View, by default) since you have not yet entered any values. Once in the Variable View, under the column “Name,” type a new name for the variable name you wish to change. You can quick-jump to the Variable View screen by double-clicking on the generic variable name at the top of the column. You can enter a new name for the variable on the Variable View tab. New variables will be given a generic name (e.g. Right-click an existing variable name and click Insert Variable orĪ new, blank column will appear to the left of the column or cell you selected.You can now insert a variable in several ways:.In the Data View window, click the name of the column to the right of of where you want your new variable to be inserted. Don't forget to periodically save your progress as you enter data. Repeat these steps for each variable that you will include in your dataset.In this example, the first person’s class level is “2,” the second person’s is “1,” the third person’s is “1,” the fourth person’s is “3,” and so on. For example, the first person’s information should appear in the first row, under the variable column School_Class. For each student, enter a value for their class level in the cell that corresponds to the appropriate row and column. In this example, cases represent students. You can see that School_Class appears in the first column in this example. Any variable names that you entered in Variable View will now be included in the columns (one variable name per column). (The default is two decimals.)Ĭlick the Data View tab. I will also specify 0 decimals since my variable values will only include whole numbers. In this example, I will type “School_Class” since I plan to include a variable for the class level of each student (i.e., 1 = first year, 2 = second year, 3 = third year, and 4 = fourth year).
Type the name for each variable that you plan to include in your dataset. You can also enter other information about the variable, such as the type (the default is “numeric”), width, decimals, label, etc. Type the name for your first variable under the Name column. When you enter values for your data in the spreadsheet cells, each value will correspond to a specific variable (column) and a specific case (row).Ĭlick the Variable View tab. The rows will represent cases that will be a part of your dataset. You will also notice that each row is labeled with a number (“1,” “2,” and so on). You will notice that each of the columns is labeled “var.” The column names will represent the variables that you enter in your dataset. If you already have another dataset open but want to create a new one, click File > New > Data to open a blank spreadsheet. When you open the SPSS program, you will see a blank spreadsheet in Data View.
