The weights (in kg) of 7 cousins in a family are 54, 62, 65, 70, 60, 59, 55.
Find the median weight.
Given:
The weights (in kg) are: 54, 62, 65, 70, 60, 59, 55.
Concept Used:
The median is the middle value when the data is arranged in ascending order.
Solution:
Arranging the weights in ascending order:
54, 55, 59, 60, 62, 65, 70
Since there are 7 observations (odd number), the median is the 4th value.
Thus, Median = 60 kg.
