Result of a Likert-type scale survey of student of the difficulty and interest level of the individual laboratory exercises composing this experiment^a

	Too				Too	Not				Very
	easy		= >		difficult	interesting		= >		Interesting
	1	2	3	4	5	1	2	3	4	5
Minipreps, restriction digest	1	9	70	10	2	0	8	20	37	28
Yeast transformation	0	4	74	12	0	0	2	12	39	40
Yeast phenotypic analysis	0	6	69	12	1	0	1	9	32	51
Southern blotting	0	5	43	4	0	0	2	8	21	22

The numbers in each column represent the number of students assigning a particular score to each question. Not all students answered all questions. Southern blotting was performed for 3 of the 5 surveyed yr, so there are fewer student respondents.
