Obtaining the Sum of Three Numbers

• Enter 1,2, and 3 in columns A1,A2, and A3• Under Formula click the “More Functions” and

choose Statistical • From Statistical choose ”AVERAGE”• Enter the correct column, e.g.

AVERAGE(A1:A3), then click • The result for the mean, which Excel calls

AVERAGE, will appear

To obtain the Variance of the Same Three Numbers, From “Statistical” Choose ”VARA” Enter 1,2, and 3 in the Small Window Below

and Click “OK”

To obtain the Standard of Deviation for the Same Three Numbers From “Statistical” Choose ”STDEVA” Enter 1,2, and 3 in the Small Window

Below and Click “OK”

To obtain Different Values for Error Function Choose Engineering Function, Then ERF, the Value of the

Error Function e.g. Between 0<E<100 is 1, and is Printed

Below

To obtain Another Value for the Error Function Choose Engineering Function, then ERF, Choose the

Value of the Error Function Between 0<E<.7. The Result Is .677

From the Math & Trig, the “Green Folder “ Calculate

• SIN of 1.6• Cos of 3.14158• PI• SQRT of 9• LOG10 of 100• SUM of 1, 2, 3• EXP of 1• LOG of 2

“LOG” of 1000000 is 6

Using Excel Formulas to Obtain Simple Statistics

• Enter 1,2, 3, 4, and 5 into column A1 to A5• Open Formulas• Enter “=“, click on the sum symbol, then

enter: (A1:A5)• The formula should look like: “=SUM(A1:A5)”• Click enter• This gives the sum of numbers 1,2,3,4, and 5

Using Excel Formulas to Obtain Simple Statistics (Chi Squared)

• Use the arrow next to the AutoSum under formulas and calculate Sum, Average, Count Numbers and so on using the data that you have on columns A1 to A4

• Obtain the CHITEST for: 2 3 4 5 6 and 4 4 4 4 4 Using CHITEST Function

• First create 2 columns containing the above 2 vectors• Then Statistical->CHITEST, enter the Actual Range

and then the Expected Value

Performing the FTEST

To the left is the answer for the FTEST

Performing Covariance Analysis

5.2 to the left is the ans.

Pearson Correlation

Pearson Corr. Is equal .997

Obtaining the Slope Between Two Columns

The slope is:

The slope is .382
