obtaining the sum of three numbers
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
slide3

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”

slide4

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”

slide5

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

slide6

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
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
using excel formulas to obtain simple statistics
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
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
