No statistical significance but observable trends
There is high variance within each group. Even though there is a mean difference between the groups, there is a high amount of spread within just treatment A or just treatment B.

From a statistical point of view, the difference between the groups could be due to chance because of the large spread relative to the small mean difference. 

Due to the amount of randomness observed - if we did ran the experiment again, treatment B mean could be higher than treatment A mean.
