I am trying to do a lab report and I cannot figure out how to set up a
frequency report on my project. I figured out my other question about the
conversions. Now I'm onto this part of the project.

Suppose you have observations of Apgar numbers -- or some other measured
quantity -- in A1:A100. Apgar numbers range from 0 to 10, and the important
diagnostic ranges are 0 - 3, 4 - 7 and 8 - 10. So your bin range could have
the number 3 in B1, 7 in B2 and 10 in B3.

With that setup, select a one-column, three-row range such as C1:C3. Type
this formula:

=FREQUENCY(A1:A100,B1:B3)

but don't press Enter yet. First, simultaneously hold down Ctrl and Shift,
and as you're holding them down, press Enter. This keyboard sequence
array-enters the formula, and is required for various Excel functions to
work properly -- including FREQUENCY. With C1:C3 selected, the array formula
will fill all three cells.

BTW, if you want to create a bin for each unique number in the data array,
you can use the data array itself as the bin range -- e.g.:

=FREQUENCY(A1:A100,A1:A100)

(Bryce Ulrich taught me that, which shows you how far back I go.)

See the documentation on LINEST or TRANSPOSE, e.g., for information on using
array formulas that have multiple rows _and_ columns.
