Question

two sets of data are shown in the table.
data set a: 4, 5, 6, 7, 7, 8, 8, 10, 12
data set b: 5, 6, 7, 8, 9, 10, 11, 12, 15
calculate the median for each data set.
for data set a, the median is 7.444.
for data set b, the median is 9.222.
for data set a, the median is 7.
for data set b, the median is 9.
for data set a, the median is 9.222.
for data set b, the median is 7.444.
for data set a, the median is 9.
for data set b, the median is 7.

Explanation:

Step1: Find median of Data Set A

Data Set A has 9 values (odd number). The median is the middle value (5th term when ordered). Ordered data: 4, 5, 6, 7, 7, 8, 8, 10, 12. 5th term is 7.

Step2: Find median of Data Set B

Data Set B has 9 values (odd number). Median is the 5th term. Ordered data: 5, 6, 7, 8, 9, 10, 11, 12, 15. 5th term is 9.

Answer:

For data set A, the median is 7.
For data set B, the median is 9.
