I have a name column (A) and a test score column (B) on my first sheet. In the test score column, each student receives a score out of 100.

I want to seperate those students into 3 groups on another sheet. Group 1, 2, and 3 respectively. Group 1 would be students who received a 90 or above, Group 2, 80 and above, and Group 3, less than 80.

I want those lists to populate automatically by student name based on their score. The problem I am having using an if/then function is it returns blank cells in each group. I want it to index the list so that all students names are together without any blank cells. So if there are 10 students who recieved 90 or above their names populate the first 10 cells on the Group 1 column. I know excel can do this, but cannot get it to work in numbers.

Help!

What order do you want the names to be in in the three category tables? Ordered by name, or score?

Here's a possible implementation:

You have three calculated columns added to your main record to categorize the results. Data from the AllScores table are then pulled into separate class tables based on the calculations.

AllScores::C2 is:

=IF(B2>=90, "A", IF(B2>=80, "B", "C"))

AllScores::D2 is:

=COUNTIF(OFFSET(\$C\$1, 0,0, ROW()), C)

AllScores::E2 is:

=C&D

Select these three cells and Fill to the bottom of the table.

A::A2 is:

=IFERROR(INDEX(AllScores, MATCH("A"&ROW()-1, AllScores :: E, 0), 0), "")

A::B2 is:

=IFERROR(INDEX(AllScores, MATCH("A"&ROW()-1, AllScores :: E, 0), 2), "")

Select these two cells and Fill to the bottom of the table.

For tables B and C, substitute B or C where you see that letter in quotes in the formula.

Is this what you had in mind?

Sort the main table that way and the groupings will follow.
