Suppose we have assigned grades for the 16 (student) scores in our data:
Table 1: Table to update
GRADE COUNT
Grade A for students who scored 2 90; B for students who
scored 2 80 and < 90; C for students who scored 2 70 and <
80; D for students who scored 2 60 and < 70; F for students
A
9
B
2
who scored < 60.
C
1
Following the above grade scheme, we observe that we have
9 students who received grade A,
D
2 student received grade B,
F
1
1 student received grade C,
O students received grade D and
1 student received grade F.
This is reflected in Table-1. You must append/update this Table-1 with your
exam scores. Check the example below for help.
