S. No	Group 1	Group 2	Group 3	Group 4
1	1	2	3	5
2	1	2	4	5
3	2	2	4	5
4	2	3	4	6
5	2	3	5	6
6	6	8	13	18
7	7	9	15	19
8	7	9	15	19
9	8	10	17	20
10	8	12	17	23
11	26	43
12	29	49
13	31	52
14	34	67
15	36	96

Compute mean, standard deviation, coefficient of variation and 5 key percentiles for these data. Are these data skewed do patients in this DRG seem to have homogeneous lengths of stay? Which measures if any must be prosecuted in description of these data? Describe your answer.
