TABLE 1.

Statistical comparison of grades from students who participated in the grandma hypothesis microbiome project (2019) and students who did not (2018).

Student*	PHG2018	PHG2019	PHG2018	PHG2019
	PS4	PS4	PS5	PS5
Mean	7.64	8.55	7.59	8.65
Median	7.5	8.75	7.5	8.75
SD	0.92	1.01	1.04	0.92
MW-test	82 (p=0.050)		85 (p=0.036)
T-test	2.16 (p=0.040)		2.40 (p=0.027)

The grades are for two problem sets given in the PHG course and focused on the analysis of metataxonomic data using bioinformatic tools.

PHG = Public Health Genomics; PS = problem set; MW = Mann-Whitney U test; SD = standard deviation.
