Building
Frequency Tables in Excel
1. Copy data array
into a single column on a new sheet (I'll assume you've copied 8200
entries into Column A, but you can use any column).You select
individual sheets by the tabs at the bottom of the Excel window. If
desired you can create a new sheet from the Insert function on the tool
bar across the top. Clicking on a tab's label allows you to enter
a new name.
2. Highlight the
entire column of entries. From the Data function of the tool bar,
Sort this list into
ascending order.
3. Create an
adjacent column of BIN boundaries which will define the histogram you
want to build. For example entering 548, 549, 550,...,682, 683
down
through C1:C136 will allow you to build a histogram with a range
from 548-683 (with 135 total bins).
4. Select D1 as a
"formula" cell, with =FREQUENCY(A1:A8200,C1:C136) (where 8200 should be replaced by the actual number of data entries you copied
into Column A). Then select the full target range D1:D137
(or just D column?), hit [F2] and then press CTRL+SHIFT+ENTER. Notice column D is set one more entry long
than C!
5. With the new
frequncy table output column highlighted, click on Chart/Plot
icon.
Select bar graph. You will see plotted histogram.
Select [Series] tab.
Click in the Categroy (X) axis labels: field
and highlight
C1:C136 or type in as
=Sheet1$C$1:$C$136
