First Excel Exercise
Using the data set (Excel spreadsheet Nations.xls), write formulas to produce
the following statistics for the variable population (POPULAT) which is
stored in cells D3 through D26:
mode
median
mean
standard deviation
variance
skewness
kurtosis
maximum value
minimum value
range
Q3
Q1
the Interquartile Range (IQR)
the z-score for the population of the Netherlands
NOTE: Excel formulas are NOT “case sensitive” (i.e., capital letters are
treated the same as lower case letters).
The Excel formulas for these statistics are:
=mode(cell#:cell#)
=median(cell#:cell#)
=average(cell#:cell#)
=stdev(cell#:cell#)
=var(cell#:cell#)
=skew(cell#:cell#)
=kurt(cell#:cell#)
=max(cell#:cell#)
=min(cell#:cell#)
=quartile(cell#:cell#,quartile#)
(e.g., quartile# would be 3 for the third quartile, 1 for
the first quartile)
You must construct values for the range, the interquartile range, and the zscore yourself by using the cell designations in which the appropriate
components are to be found.
For example, the range would be constructed as:
=(cell# containing the formula for max - cell# containing the formula for
min)
The Interquartile Range (IQR) would be constructed as:
=(cell# containing the formula for Q3 - cell# containing the formula for
Q1)
And the z-score for the Netherlands would be constructed as:
=standardize(cell# for the population of the Netherlands, cell# containing
the formula for the mean of POPULAT, cell# containing the formula for the
standard deviation of POPULAT)
Note that Excel formulas must start with an equal sign to designate the
content of the cell as a formula rather than a number or word.
Simply use the range of cells (i.e., D3 through D26) in the argument (i.e.,
place them inside the parentheses, separated by a colon [“:”]).
ALL statistics are to be performed on values of population for these 24
nations, the variable POPULAT in Column D, cells D3 through D26.
Place the names of the statistic in cells A28 through A41; place the formulas
in the corresponding cells B28 through B41.
If you need “on the spot assistance,” simply use the Excel helps (click on
“Help” above the first toolbar) or find the statistic in question in the
statistical function pull-down box by clicking on “fx”.
Submit ONLY PAGE 1 of this spreadsheet in portrait form (i.e., standard 8.5 x
11” format) with your name and social security number at the top.
Due when class convenes on Wednesday, September 20.
