The complete question in the attached figure

we know that
The interquartile range is a measure of where the “middle fifty” is in a data set

the interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1

Group A [121135423]
Step 1: Put the numbers in order
[1 1 1 2 2 3 3 4 5]
Step 2: Find the median
[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 [323222112]
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
