Answer :
Weight of the 13 male eleventh graders is 157.23 pounds. Median is the number in the middle, ranked from least to greatest.
Median weight = 148+140+159+141+151+156+173+167+160+159+146+174+170
= 2044/13
= 157.23
Median :
The value that separates the upper half of a population, a data sample, or a probability distribution from the lower half is known as the median. It could be referred to as "the middle" value for a data set. The value in the middle of a data set is called the median. This means that 50% of the data points have values that are smaller than or equal to the median, and 50% of the data points have values that are higher than or equal to the median. First, you count the number of data points (n) and arrange them in ascending order for a small data set.
How is the Median Calculated?
The middle value in a set of data is called the median. First, arrange the data in ascending order from smallest to largest. Divide the total number of observations by two to get the midpoint value. Round that number up if there are an odd number of observations, and the value in that position is the median. Take the average of the values found above and below that position if the number of observations is even.
