we know that
The interquartile range is a measure of where the “middle fifty<span>” is in a data set
</span>
</span><span>Group A [1 2 1 1 3 5 4 2 3]
</span>Step 1: Put the numbers in order
<span>[1 1 1 2 2 3 3 4 5]
</span>Step 2: Find the <span>median
</span>[1 1 1 2 2 3 3 4 5]
Step 3: Place parentheses around the numbers above and below the median
[(1 1 1 2) 2 (3 3 4 5)]
Step 4: Find Q1 and Q3
[(1 1 1 2) 2 (3 3 4 5)]----> Q1=1 Q3=3
IQRA = Q3 – Q1--------> 3-1=2
Group B [3 2 3 2 2 2 1 1 2]
Step 1: Put the numbers in order
[1 1 2 2 2 2 2 3 3]
Step 2: Find the median
[1 1 2 2 2 2 2 3 3]
Step 3: Place parentheses around the numbers above and below the median
[(1 1 2 2) 2 (2 2 3 3)]
Step 4: Find Q1 and Q3
[(1 1 2 2) 2 (2 2 3 3)]----> Q1=1 Q3=2
IQRB = Q3 – Q1--------> 2-1=1
IQRA=2
IQRB=1
the answer is the option
The interquartile range for Group A students is 1 more than the interquartile range for Group B students

Step 3: Place parentheses around the numbers above and below the median
[(1 1 1 2) 2 (3 3 4 5)]
Step 4: Find Q1 and Q3
[(1 1 1 2) 2 (3 3 4 5)]----> Q1=1 Q3=3
IQRA = Q3 – Q1--------> 3-1=2
Group B [3 2 3 2 2 2 1 1 2]
Step 1: Put the numbers in order
[1 1 2 2 2 2 2 3 3]
Step 2: Find the median
[1 1 2 2 2 2 2 3 3]
Step 3: Place parentheses around the numbers above and below the median
[(1 1 2 2) 2 (2 2 3 3)]
Step 4: Find Q1 and Q3
[(1 1 2 2) 2 (2 2 3 3)]----> Q1=1 Q3=2
IQRB = Q3 – Q1--------> 2-1=1
IQRA=2
IQRB=1
the answer is the option
The interquartile range for Group A students is 1 more than the interquartile range for Group B students
