The correct answer is D. Median.
The median is the middle value in a set of data. It is the value that divides the set into two equal parts, with half of the values being less than the median and half being greater than the median.
The median can be found by arranging the data in order from least to greatest and then finding the middle value. If there is an even number of values, the median is the average of the two middle values.
The median is a robust measure of central tendency, meaning that it is not affected by outliers. It is also a simple and easy-to-understand measure of central tendency.
The arithmetic mean is the sum of the values in a set of data divided by the number of values. It is the most common measure of central tendency.
The third quartile is the median of the upper half of a set of data. It is the value that divides the upper half of the data into two equal parts, with half of the values being greater than the third quartile and half being less than the third quartile.
The mode is the most frequent value in a set of data. It is the value that occurs the most often in the set.
The mode is not a robust measure of central tendency, meaning that it can be affected by outliers. It is also not always a meaningful measure of central tendency, as there may be multiple modes in a set of data.
