Arrange the numbers in order from smallest to largest:
12, 18 , 25, 26 , 30, 31 , 34
Find the highest and lowest numbers, those would be where the black dots go on the number line.
Lowest number = 12
Highest number = 34
The line inside the box would be the Median number of the set.
Find the median ( middle value):
Since there is an odd amount of numbers the median would be the middle number:
Middle number = 26
The graph that has the black dots on 12 and 34 and the line of 26 is the first one
