Hi, 

Please can you let me know few examples of what do we mean by  â€œAre external conditions  same†when we perform hypothesis testing. In this case the developers doing testing may be different, however they are using the same code and same machines. So should we say that external conditions are same or does it even depend on the skills of people and say that external conditions are different.’

 

Please suggest.

Dear Bharani,

 

Here is an example. Let us say in Back Office data entry work, you are trying to test time taken to upload a transaction using Software A and Software B. If you collect data from different operators for multiple transactions, you will say that the external conditions are different, as the skills may vary by the operator, the comfort levels with two softwares etc may be different. However, if you collected data for the transaction for the same operator using both Software A and Software B, you would say that the external conditions are the same, since in the latter case you can truly test if the Software is causing any difference in time taken to upload and you have removed the "noise" that could have been introduced by different skills from different operators.

 

In your case, you would have to elaborate on what is it that you are trying to test. If your intent is to test if the time varies by the tester, and you are keeping the code and the machine same (and nothing else is changing either e.g.length of the code etc) you could say that the external conditions are the same. This is what I can say with the level of information available.
