Hi Diana, are you using WordStat too? Can you maybe explain in more details the steps you have taken?

Diana Spulber

Hi Jadranka, no I do not use WordStat , I bought QDA Miner 4, I inserted the text to be analysed, I created the variables I put on bottom analyze and nothing happened

Diana, maybe you can watch the video at http://provalisresearch.com/products/qualitative-data-analysis-software/. It's very illustrative. Try to figure out if your screen looks similar, specially Cases, Variables and Codes. You can't "analyze text" without codes, a sort of categories. But you can retrieve text for the specific word like "nationalism", or the combination of words and phrases. For this you must use Retrieval part of the menu.

Hi Diana

Would you say QDA miner is not worth the money it costs?

Normand Peladeau

Diana,

From your description, it seems that you may be trying to create a blank project by defining the structure only (adding variables and descriptions). There are 5 options to create a project and this is probably the hardest one. Please have a look at the following web page:

http://provalisresearch.com/resources/tutorials/

You will find there tutorials on ways to get started and create a project from documents or from data files (Excel, MS Access, Tab or CSV files, SPSS, Stata, etc.).
