Statement of the Problem

            The researchers aimed to determine if Aloe barbandesis (Aloe Vera) extract can be a main component of a marker ink.

            Specifically, the researchers sought to study if there is a significant difference between the experimental product in terms of:

1. Color
2. Volatility
3. Shelf life 
4. Permanence

Discussion

           For the statistical analysis of the tests; since the calculated F-value 3.52 was less than the tabular F-value 4.38, there was no significant difference between the colors of the samples. There was also no significant difference between the shelf life of the samples since the calculated F-value 2.36 was less than the tabular F-value 4.38. However, there was a significant difference between the samples’ volatility since the calculated F-value 5.25 was greater than the tabular F-value 4.38. For the permanence of the samples, there was also a significant difference since the calculated F-value 8.29 was greater than the tabular F-value 4.38. The null hypothesis was supported in terms of the color and shelf-life of the samples. However, the permanence and volatility test validated the alternative hypothesis.
