Do not select a format that does not match the current format of the values. Now click the Data View tab to view your data; your dates should now appear in the format you selected. Note : If you select a new format that includes space for information that does not actually appear in your dataset, it will appear as 0s in the data. For example, if your data only includes information about the month, day, and year, and you select a format that also includes space for the hour, minute, and second, values will appear like this one: JAN When writing dates, it's common to see individuals abbreviate the year to two digits, especially in contexts where the century is "obvious" to the reader.

This is fine when making notes to yourself, but when you're trying to compile data for analysis, this can be hugely problematic, especially when working with data that covers a large time range, or is very far in the past.

In general, we recommend always using four-digit years when entering data for dates. But sometimes you may not be in control of how the data was entered -- you may receive or request a dataset where the dates only used two-digit years.

For these situations, it's important to know how to appropriately define the century range in SPSS. If you didn't have any other context clues, you'd probably base your guess on the current year The default century range in SPSS is based on the current year: it will start the range at 69 years prior to the current year and end the range at 30 years after the current year source. Why does the century range matter? If you are going to compute elapsed time, or want to use your date variables as a predictor in a model, you can imagine how problematic it would be if one of the dates was off by years!

For this reason, it's critical that you specify the appropriate century range when working with dates containing two-digit years. By default, Automatic will be selected and two-digit years will be understood to fall in the range of the current year minus 69 to the current year plus You can change the century range by clicking Custom , which will allow you to input a new beginning year and the end year will be imputed for you.

When you are finished, click Apply , and then click OK. The yyyy to the right of the equals sign is the desired beginning year for the century range. SPSS conveniently includes a Date and Time Wizard that can assist with transformations and calculations that involve date and time variables.

Although there are many options, it is useful to begin by first reading about how dates and times are represented in SPSS.

We have selected this option Learn how dates and times are represented in the Date and Time Wizard window depicted above. Now, click Next. You will see the following window. When you are finished reading, click Back to return to the main Date and Time Wizard menu. Note that the Date and Time Wizard can assist with many tasks related to dates and time, including:. We will not cover each of these options in this tutorial, but we will cover one of the most common uses for the Date and Time Wizard: calculations involving dates and times.

If you have datetime variables in a text or CSV file, SPSS will often read those variables in as string or character variables, instead of treating them as actual dates. In order to have those variables correctly recognized, you'll need to convert them from string to date.

In the sample dataset, the variable enrolldate date of college enrollment contains dates in the form dd-mmm-yyyy , but was read into the dataset as a string variable. Let's convert that variable from a string to a numeric date. Sometimes you may need to calculate the length of time that has passed between two points in time.

If you already know SPSS there is no learning curve. Does anyone know if PSPP results are reliable? Also, does anyone know if people are starting to widely publish with PSPP? PSPP just still misses some functions. However currently pspp added factor analysis and reliability analysis. I prefer using pspp because it is free open source!!

Both the links I gave are reputable, to the best of my knowledge. Your email address will not be published. I have not tried it yet, but it does look promising. This is the description from its website: It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. Sounds pretty good, huh? Comments thank you. Klasse gemachte Seite, das Layout gefaellt mir echt gut!

War sicher ne menge Aufwand. Hi SO, Fair enough. I like your idea, though, of hiring a programmer for the price of an add-od module. Know any? Anyone else? Recode all values greater than or equal to some number. All other values : Applies to any value not explicitly accounted for by the previous recoding rules. If using this setting, it should be applied last. Output variables are strings: The new variable will be a string variable. Convert numeric strings to numbers: This option can only be used when your input variable is a string, and will be grayed out otherwise.

If the input variable is a string, but the data values themselves are valid numbers, selecting this option will convert the number strings into actual numbers. If any other character symbols appear in the data values, the conversion will fail, even if the numbers are otherwise valid. This includes dollar signs and percent symbols. END IF. Operator Symbol Definition Operators for logical statements.

Execution of this command stops. Example: Merging Categories Problem Statement Class ranks for high schools and colleges are are nicknames for what year of study the person is completing: "freshman" first-year , "sophomore" second-year , "junior" third-year , "senior" fourth-year.

Running the Procedure We will show three different ways of defining the categories that produce identical results. In the Output Variable area, give the new variable the name RankIndicator. Click the Old and New Values button. Then click Add.

When finished, click Continue. Click OK. Method 2 This method uses ranges. Define the underclassmen group 1 : In the Old Value area click Range and enter 1 in the first box and 2 in the second box. In the New Value area click Value and enter 1. Define the upperclassmen group 2 : In the Old Value area click Range and enter 3 in the first box and 4 in the second box.

In the New Value area click Value and enter 2. Method 3 This method uses the "Lowest thru" and "thru Highest" ranges. Example: Dichotomizing a Continuous Variable Problem Statement One important use of the Recode procedure is dichotomizing or discretizing a continuous variable. Discussion Why didn't we use the "Range" option to specify category 2? Problem Statement Suppose we have test scores as percentages, and want to convert those percentages to a letter grade. Imagine a number line: In that instance, the score Running the Procedure This computation must be done using syntax.

Highlight the syntax, then press the Run Selection play button. Output If the recode was performed successfully, we should see the new variable in the Data Editor window. Report a problem.
