Hi, Please can you let me know few examples of what do we mean by “Are 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.
