The median of the data set 3, 7, 8, 12, x is 8. What is the value of x? (2023)

The median of the data set 3, 7, 8, 12, x is 8. What is the value of x? (2023)

Step 1: Understand that the median is the middle value of a data set when it is arranged in order.
Step 2: Arrange the data set 3, 7, 8, 12, x in ascending order.
Step 3: Since the median is given as 8, we know that the middle value of the ordered data set must be 8.
Step 4: If x is less than or equal to 8, the ordered data set will have 8 as the middle value.
Step 5: If we set x = 6, the ordered data set becomes 3, 6, 7, 8, 12.
Step 6: In this ordered set, the middle value (3rd number) is 8, which matches the given median.
Step 7: Therefore, the only value for x that makes the median 8 is x = 6.
