How do you fix the date

Postby nooblet » Tue Oct 20, 2015 4:50 am

Hi, I have an assignment using SPSS, where we have been given a data set and need to use the data for a research question. However, there are many errors in the data (put there on purpose) and we have to fix those errors first.

The data set is based on patients in a hospital. I calculated a new variable, "length of stay" (LOS). However since some of the dates are wrong, the LOS is inaccurate for some patients. For example, it is a negative number. Here is a specific example:

Date of arrival: 30.12.2002
Date of separation: 01.01.2002.

As you can see, the year is the same when it should be the next year, 2003. This gives a LOS of -363.

I am wondering, is there a way in SPSS to check and fix errors like this? Or in general, is this data simply disposed of?

Thanks.

There is no way to fix this automatically in spss.
Personally, I would not use these data because you cannot be sure what the correct data "should" be, therefore it is unreliable
