The median weight of the students is: 157 pounds
What is the median of the data?
The median of a data set is the middle value when the data points are arranged in ascending or descending order. If the number of data points is odd, the median is the middle value. If the number of data points is even, the median is the average of the two middle values. It is a measure of central tendency that is not skewed by extreme values.
Let us arrange the given data in ascending order to get:
141, 144, 151, 153, 161, 166, 168, 171
Thus, the median is (153 + 161)/2 = 157 pounds
