Question 41

A materials scientist measures the degradation time, in days, of two new bioplastic formulations under controlled composting conditions. Table 1 shows the results for 9 samples of each formulation.

Table 1: Biodegradation Times (days)

Formulation Alpha	Formulation Beta
12	8
4	7
11	8
11	6
3	8
5	5
3	9
10	8
7	4

Explain why the median may be a more appropriate measure of central tendency to use with the data for Formulation Alpha than the mode.
