Yes!  You may want to delete individual clicks or conversions if they were tests or did not meet the criteria of your goal, as these can skew your stats. 

To do this you need to visit the ‘Report’ tab in your Campaign Overview section. 

Select the clicks/conversions figure (you’ll notice they will be underlined) to see a pop-up that gives you the details of the individual clicks/conversions. 

You can then delete any that you do not want included in your reports.
