  -was there a large or small sample size
• range of data studied eg are values close together , should they investigate a wider range of values?
  why is there no sig diff if the standard deviations do overlap

Question 2

if you are talking about stats tests say

Answer 2

no stats test and no standard deviations to show if overlap occurs so difference is not significant

Question 3
