hi,
i have this basic project of a class of students where i need to gather information in regards to exam results. Using an if statement i've managed to assign each student a grade (A+ to D) but now need to log the number of failures and the percentage failed in a separate cell. My guess is it involves another if statement but i'm unsure as to how i might code this. I've tried stuff like 'IF Final Result = 'D' etc but i seem to be a little way off & i'm new to excel.

thx for any replies....
 

Excel Facts

Why are there 1,048,576 rows in Excel?
The Excel team increased the size of the grid in 2007. There are 2^20 rows and 2^14 columns for a total of 17 billion cells.

To get you started (this is from the Excel help file):

If AverageScore is Then return
Greater than 89 A
From 80 to 89 B
From 70 to 79 C
From 60 to 69 D
Less than 60 F


You can use the following nested IF function:

IF(AverageScore>89,"A",IF(AverageScore>79,"B",
IF(AverageScore>69,"C",IF(AverageScore>59,"D","F"))))
In the preceding example, the second IF statement is also the value_if_false argument to the first IF statement. Similarly, the third IF statement is the value_if_false argument to the second IF statement. For example, if the first logical_test (Average>89) is TRUE, "A" is returned. If the first logical_test is FALSE, the second IF statement is evaluated, and so on.

Chris,

That is an example how to use IF. However, the task for which the formula is set up can better be done with VLOOKUP or LOOKUP...

=VLOOKUP(A1,{0,"F";60,"D";70,"C";80,"B";89,"A"},2)

or

=VLOOKUP(A1,Grades,2)

where Grades a 2-column list, consisting of

{0,"F";
60,"D";
70,"C";
80,"B";
89,"A"}

By the way,

=COUNTIF(Range,"F")

would give the number of failures. Once you have that, you can determine the percentage failed.
