Step 1: Put the numbers in order. 1,2,5,6,7,9,12,15,18,19,27<span>Step 2: </span>Find the median (How to find a median). 1,2,5,6,7,9,12,15,18,19,27<span>Step 3: </span>Place parentheses around the numbers above and below the median. Not necessary statistically–but it makes Q1 and Q3 easier to spot. (1,2,5,6,7),9,(12,15,18,19,27)<span>Step 4: </span>Find Q1 and Q3 Q1 can be thought of as a median in the lower half of the data. Q3 can be thought of as a median for the upper half of data. (1,2,5,6,7), 9, ( 12,15,18,19,27). Q1=5 and Q3=18.<span>Step 5: </span>Subtract Q1 from Q3 to find the interquartile range. 18-5=13. Hope this helped:) -BRIEMODEE:)
It would be the first graph because |x| >5 is solved in two cases
The first case you keep everything the same, just get rid of the absolute value bars
x>5
The second case, you need to switch the sign and make the 5 negative
x<-5
When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,
You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right
