What is the second mode?

Question

Find the mean, median, and mode of the given set of raw data. (Enter solutions for mode from smallest to largest. If there are any unused answer boxes, enter NONE in the last boxes.)

1.1	1.7	0.6	1.4	0.9	0.6	1.8	1.6	1.1
0.7	1.6	1.2	2.2	0.8	1.9	1.6	1.4	2.1

Answer 1

mean= arithmetic average = sum divided by 18 = sum/18 =21.6/18 =10.8/9 =108/90

=1.2

median = 1.4 There are 18 entries, the middle terms are the 9th & 10th largest both=1.4 both equal to the 9th & 10 smallest entries as well

.5, .6, .6, .7, .8, .9, 1.1, 1.1, first 8

1.4, 1.4 middle two

1.6, 1.6, 1.6, 1.7, 1.8, 1.9, 2.1, 2.2 last 8

mode = 1.6 which has frequency =3, more than any other entry. .6, 1.4, 1.1 each have frequency = 2. the rest, the other 9 entries each frequency just = 1. It's unimodal, not bimodal. Write NONE in the last box, next to the 2nd "Mode"
