A median is only meaningful for interval or ordinal data and not for ratio data.

• This statement is true. The concept of a median is applicable to data that can be ordered or ranked, such as interval or ordinal data. Ratio data, on the other hand, involves a meaningful zero point and does not have a natural order, so the concept of a median is not applicable.

Medians can be calculated no matter how the data is arranged.

• This statement is true. Unlike the mean, which is affected by the arrangement of data, the median can be calculated regardless of how the data is arranged. It only depends on the middle value(s) of the data set.

Medians are affected by outliers.

• This statement is true. Outliers, which are extreme values that differ significantly from the rest of the data, can affect the value of the median. However, compared to the mean, the median is less sensitive to outliers because it only considers the middle value(s) and is not influenced by extreme values.

For an even number of observations, the median is the mean of the two middle numbers.

• This statement is true. When there is an even number of observations, the median is calculated by taking the average of the two middle numbers. This ensures that the median represents the central tendency of the data set.
