What is the median survival time (in months)?

Answer 1

The median survival time for individuals with hepatic angiosarcoma in the given data set is 4 months, which is calculated by averaging the two middle values from the ordered survival times.

Step-by-step explanation:

To calculate the median survival time in months for the individuals with hepatic angiosarcoma, we first need to arrange the survival times in numerical order: 1, 3, 5, and 19 months. With an even number of observations (four in this case), the median is the average of the two middle numbers.

Therefore, the median survival time is the average of 3 and 5 months.

The calculation for the median is (3 + 5) / 2, which equals 4 months.

Hence, the median survival time for this group is 4 months.
