Answer:
-1.8!
Step-by-step explanation:
it's just the answer I think
Okay so you put the numbers in order:
70, 74, 81, 82, 83, 91, 94.
Then you find the median which will be Q2:
82.
Once you have the total median, you find the midpoint of the first and last part:
70, 74, 81. Midpoint/Q1=74
83, 91, 94. Midpoint/Q3=91
Now that you have that, you subtract Q3 and Q1.
91-74=17
17 is your IQR.
Rule: Any positive number is always larger than any negative number.
For example, 10 is larger than -2. So we write 10 > -2.
The same goes for 8 & 1/4 vs -8 & 1/4. It doesn't matter if we involve fractions or decimals.
Visually, positive numbers are to the right of 0 on the number line. Negative numbers are to the left of 0.
Stuff on the right is larger than stuff on the left.
