  2. Drag the variable of interest from the left into the Variables box on the right.
  3. Click Options, and select Mean and Standard Deviation.
  4. Press Continue, and then press OK.

How do you calculate variables?

Calculate total variable cost by multiplying the cost to make one unit of your product by the number of products you’ve developed. For example, if it costs $60 to make one unit of your product and you’ve made 20 units, your total variable cost is $60 x 20, or $1,200.

What is the use and function of compute variable option in SPSS?

To compute a new variable, click Transform > Compute Variable. The Compute Variable window will open where you will specify how to calculate your new variable. A Target Variable: The name of the new variable that will be created during the computation. Simply type a name for the new variable in the text field.

How do you find the variable if a case is in SPSS?

  1. From the menus choose: Transform > Compute Variable…
  2. In the data transformation dialog box, click If.
  3. Select Include if case satisfies condition.
  4. Enter the conditional expression.

What are the variable types in SPSS?

Variable Types

  • Numeric. Numeric variables, as you might expect, have data values that are recognized as numbers.
  • String. String variables — which are also called alphanumeric variables or character variables — have values that are treated as text.
  • Comma.
  • Dot.
  • Scientific notation.
  • Date.
  • Dollar.
  • Custom currency.

Why do we compute variables in SPSS?

Computing variables in SPSS refers to computing with existing variables to create new variables. One common reasons is creation of a scale measure that combines several existing variables into a single variable, such as to summarize a phenomenon of interest.

Why do we use compute variable in SPSS?

What do you mean by Compute in SPSS?

SPSS COMPUTE Existing String Variable. In normal language, COMPUTE usually refers to operations on numbers. In SPSS, however, COMPUTE is used for setting the values of string variables as well. Keep in mind here that you can’t use numeric functions on string variables or vice versa.

How to calculate a target variable in SPSS?

To compute a new variable, click Transform > Compute Variable. The Compute Variable window will open where you will specify how to calculate your new variable. A Target Variable: The name of the new variable that will be created during the computation.

How to calculate the mean and standard deviation in SPSS?

To calculate the mean and standard deviation, choose Analyze -> Descriptive Statistics -> Descriptives, as below. This will open up the following dialog box. You need to get the variable for which you want to know the mean and standard deviation into the variables box on the right (as per the image above).

Why is 6 a missing value in SPSS?

This is because 6 is a user missing value and it’s used in a basic numeric function. If the variable that’s computed doesn’t exit yet, SPSS will create it as a numeric variable having an f format. One of the implications is that we can’t directly COMPUTE new string variables but we’ll get to that in a minute.
