Final answer:
The correct answer is option d) none of the above.The median is a measure of central tendency that is used to describe the middle value in a set of data.
Step-by-step explanation:
The median is typically used for quantitative data and would not be appropriate for reporting the median for distributions of political preferences, countries of birth, or academic majors. It is calculated by arranging the data in order from least to greatest and finding the value in the middle. However, it is important to note that the median is typically used for quantitative data, which can be measured and expressed numerically.
a) Political preferences, b) countries of birth, and c) academic majors are all qualitative variables that cannot be measured numerically. Therefore, it would not be appropriate to report the median for these distributions.
The median is typically used for quantitative data that is ordinal (has a natural order), and where it's meaningful to say that one data point is higher or lower than another. Political preferences and countries of birth are also categorical data, but like academic majors, they do not have a natural order that would make the median as informative as the mode.
