3.5−6.5 12

6.5−9.5 15

9.5−12.5 13

12.5−15.5 9

⇒ Less than frequency table are as follows:

Mark Frequency

Less than 3.5 10

Less than 6.5 22

Less than 9.5 37

Less than 12.5 50

Less than 15.5 59

⇒ Greater than frequency are as follows:

Mark Frequency

Greater than 0.5 59

Greater than 3.5 49

Greater than 6.5 37

Greater than 9.5 22

Greater than 12.5 9
