Health care issues are receiving much attention in both academic and political arenas. A sociologist recently conducted a survey of citizens over 60 years of age whose net worth is too high to qualify for Medicaid. The ages of 14 senior citizens were as follows:
60
61
62
63
64
65
66
68
68
69
70
73
73
74
Determine the median age of the senior citizens.
67
71
68
87
To determine the median age of the senior citizens, we first need to arrange the ages in ascending order:
60, 61, 62, 63, 64, 65, 66, 68, 68, 69, 70, 73, 73, 74
Now we need to find the middle age, which in this case is the average of the two middle numbers (68 and 69):
(68 + 69) / 2 = 137 / 2 = 68.5
Therefore, the median age of the senior citizens is 68.5.
