List A consists of the numbers {2, 9, 5, 1, 13}, and list B consists of the numbers {7, 4, 12, 15, 18}. If the two lists are combined, what is the median of the combined list?

Recall that the median of a set of data is the value located in the middle of the data set. In the case of a data set that contains an even number of numbers, the median is the average of the two middle numbers. Combine the 2 sets provided, and organize them in ascending order:
{1,2,4,5,7,9,12,13,15,18}
Since there are an even number of items in the resulting list, the median is the average of the two middle numbers.
Median= (7+9)÷2=8
