Match the stem and leaf plot below to the correct set of data.
1 ∣ 6 means 1.6

a. 1.5, 1.5, 1.6, 2.1, 2.1, 2.1, 3.5, 3.6

b. 1.5, 1.5, 1.6, 2.1, 2.1, 2.1, 3.5, 3.6, 3.7

c. 6, 5, 5, 1, 1, 1, 1, 1, 1, 6, 6, 6, 5, 5, 5

d. 15, 15, 16, 21, 21, 21, 35, 36

Choice A is the answer

Focus on the stem and leaf plot
In row 1 we have 1.6, 1.5 and 1.5
In row 2,we have 2.1, 2.1 and 2.1
In row 3, we have 3.6 and 3.5
So the data values are: 1.5, 1.5, 1.6, 2.1, 2.1, 2.1, 3.5, 3.6

Side Notes:
We can rule out choice B because 3.7 is not a data value (there is no "7" anywhere in the leaves)
We can rule out choices C and D because they aren't even decimal values matching the format mentioned in the key of the stem and leaf plot.
