Descriptive Statistics
In this chapter, I start with statistical analysis of the data on the sheet called
Statistics in the Excel workbook Chapter 10 shown in Figure 10.1.
The data in column A contains a list of 500 students
IQs. I selected the range
A1:A500 and named the range
I used the procedure described in Chapter
4. If you expand the name box above A1 by clicking the drop-down arrow/menu to
the right of the field and then select the name DATA, it will highlight the range of
named cells A1:A500.
DATA.
DESCRIPTIVE STATISTICS
In this section I am going to calculate several frequently used statistics functions. I
will start with the mean, the highest value, the lowest value, the standard deviation,
the median, and the mode.
Let me begin with the average. I select the cell D3 where I would like the answer
to be located, and then select f x (Insert function) or use Shift
þ
F3. Choose the cate-
gory Statistical, then the function Average. See Figure 10.2.
A menu to insert the function arguments will appear
since the goal is to
compute the average of our data set, I could select the range A1:A500, but as the
range was previously named DATA, I can simply type in the word DATA and click
OK to obtain the average. See Figure 10.3.
The result is shown in Figure 10.4.
