12	6.2148
13	6.1422
14	6.2864
15	6.2647

We have taken help of MINITAB to make boxplots of this data is

The 5-point summary is

Descriptive Statistics: data

Mean	6.1729
StDev	0.0871
Minimum	6.0005
Q1	6.1181
Median	6.1719
Q3	6.2415

here we have an incusion extra of StDev to get some idea about deviation, please ignore Stdev while reporting 5-point Descriptive.
