When conducting a significance test to determine if there is
When conducting a significance test to determine if there is a difference between two treatments, with a quantitative response variable, treatments are given to different experimental units, we summarize the data by:
| computing the mean and standard deviation of each treatment group separately. | 
Solution
The correct option is:
computing the mean and standard deviation of each treatment group separately.
Because experimental units in both samples are different (independent) and we want to compare the means of both samples.
