MEAN

Enter the scores in one of the columns on the Excel spreadsheet

MEAN Enter the scores in one of the columns on the Excel
(see the example below). After the data have been entered, place the cursor where you wish to have the mean (average) appear and click the mouse button. Select Insert Function (fx) from the FORMULAS tab. A dialog box will appear. Select AVERAGE from the Statistical category and click OK. (Note: If you want the Median, select MEDIAN. If you want the Mode, select MODE.SNGL. Excel only provides one mode. If a data set had more than one mode, Excel would only display one of them.)

STANDARD ERROR

The formula for calculating the Standard Error of the mean in

STANDARD ERROR The formula for calculating the Standard Error of the mean
Excel is =stdev(''cell range'')/SQRT(count("cell range")).

Слайд 5

MEDIAN

The MEDIAN function returns the median (middle number) in a group of

MEDIAN The MEDIAN function returns the median (middle number) in a group
supplied numbers. For example, =MEDIAN(1,2,3,4,5) returns 3.

Слайд 6

MODE

The Excel MODE function returns the most frequently occurring number in a numeric

MODE The Excel MODE function returns the most frequently occurring number in
data set. For example, =MODE(1,2,4,4,5,5,5,6) returns 5.

STANDARD DEVIATION

Use the Excel Formula =STDEV( ) and select the range of

STANDARD DEVIATION Use the Excel Formula =STDEV( ) and select the range
values which contain the data. This calculates the sample standard deviation (n-1). Use the web Standard Deviation calculator and paste your data, one per line.

SAMPLE VARIANCE

Sample Variance Excel 2013: VAR Function. Step 1: Type your data

SAMPLE VARIANCE Sample Variance Excel 2013: VAR Function. Step 1: Type your
into a single column. Step 3: Type “=VAR(A1:A100)” where A1:A100 is the location of your data set (i.e. in cells A1 to A100). Press the “Enter” key to get the sample variance.

Слайд 9

KURTOSIS

KURT(number1, [number2], ...)The KURT function syntax has the following arguments:Number1, number2, ...    Number1

KURTOSIS KURT(number1, [number2], ...)The KURT function syntax has the following arguments:Number1, number2,
is required, subsequent numbers are optional. 1 to 255 arguments for which you want to calculate kurtosis. You can also use a single array or a reference to an array instead of arguments separated by commas.

Слайд 10

SKEWNESS

SKEW(number1, [number2], ...)The SKEW function syntax has the following arguments:Number1, number2, ...    Number1

SKEWNESS SKEW(number1, [number2], ...)The SKEW function syntax has the following arguments:Number1, number2,
is required, subsequent numbers are optional. 1 to 255 arguments for which you want to calculate skewness. You can also use a single array or a reference to an array instead of arguments separated by commas.

Слайд 11

RANGE

Range = maximum value – minimum valueSo if you have a set

RANGE Range = maximum value – minimum valueSo if you have a
of data such as 4, 2, 5, 8, 12, 15, the range is the highest number (15) minus the lowest number (2). In this case:Range = 15-2 = 13

Слайд 12

MAXIMUM

=MAX (number1, [number2], ...)

MAXIMUM =MAX (number1, [number2], ...)

Слайд 13

MINIMUM

=MIN (number1, [number2], ...)

MINIMUM =MIN (number1, [number2], ...)

Слайд 14

SUM

The SUM function, one of the math and trig functions, adds values.

SUM The SUM function, one of the math and trig functions, adds
You can add individual values, cell references or ranges or a mix of all three.For example:=SUM(A2:A10) =SUM(A2:A10, C2:C10)
