Why input range contains non-numeric data?

[Nickman]

When I try to do a regression analysis on my data, a box pops up saying there
is non-numerica data for the input. However, I cant find any within my data
sheet.

Are some of the cells formatted as text? Or entered with a leading
apostrophe (which amounts to the same thing)?

I selected all of the data and then formatted the cells as numbered. And as far as apostrophes go I cant find any. But the problem still persists.

Reformatting a cell does not change the value in the cell, it merely changes
the display of that value. In particular applying a numeric format will not
change text into a number. Copy an empty cell, select the input range, and
Edit|Paste Special|Add to coerce the values into numbers.

To identify which cell(s) is(are) text,
Format|Cells|Alignment|Horizontal|General. Text will be left justified while
numbers will be right justified. Alternately COUNT() only counts numbers.

If all your data look like numbers and still you have a problem. Excel need
to calculate with them to understand that its numbers. Try to write 1 into a
cell and Copy-Paste Special and multiply all the data. Then, it should work.
Alternatively you can hit F2 in every single cell. Same idea.

Numbers formatted as text have to be converted back to numbers.
Create a range of cells in the same shape as the problem data cells,
each of which contains a 1. Then Copy this range, select the top-left
cell of the problem data range, select Paste Special from the Edit
menu, click on the Multiply button in the Operations section of the
Paste Special dialog, then click OK. Your numbers will now be treated
as numbers by Excel.

Ok, so I copied and pasted special with a blank box and a bunch of random
numbers in my columns went right justified while most stayed left. But that
didn't fix anything. Then I tried all of the other suggestions and still
nothing it working. I still have random numbers sitting on the right and
cant do any data analysis. This is getting frustrating.

I think you might have space infront or behind some of your data. Use F2 in
some of the cells to make sure that there not are any "odd characters"
unvisible.
You can check this easy also by using =Left(b1,6) where 6 is numbers of
characters
you want to extract.
This formatting problems is very irritating in Excel. Numbers are not always
calculatable(if thats a word) even if its seems like it.
Good luck
