Data Analysis Dialog Box • Click on “Tools” • Select “Data Analysis” • Select statistical operation • such as Histogram
Functions • Functions are predefined formulas for mathematical operations • They perform calculations by using specific values, called arguments • Arguments indicate data or a range of cells • Arguments are performed, in a particular order, called the syntax.
Functions • Functions are predefined formulas for mathematical operations • They perform calculations by using specific values, called arguments • Arguments are performed, in a particular order, called the syntax. • For example, the SUM function adds values or ranges of cells
Easy to Use Paste Functions • AVERAGE (MEAN) • MEDIAN • MODE • SUM • STANDARD DEVIATION
Functions • The syntax of a function begins with the function name • followed by an opening parenthesis • the arguments for the function • separated by commas • a closing parenthesis. • If the function starts a formula, an equal sign (=) is typed before the function name.
The Equal Sign Then The Function Name And Arguments • =FUNCTION (Argument1) • =FUNCTION (Argument1,Argument2)
Arguments • Typical arguments are numbers, text, arrays, and cell references. • Arguments can also be constants, formulas, or other functions.
Data Array • The data appear in cells A2 through 14 • A2:A14 • Sometimes written with dollars signs • $A$2:$A$14
Sum, Average, and Standard Deviation • =FUNCTION (Argument1) • =SUM(A2:A9) • =AVERAGE(A2:A9) • =STDEVA(A2:A9)
Proportion • =COUNT • =COUNTIF • DIVIDE COUNTIF BY COUNT • =D3/D2
Frequency Distributions • There are alternative ways of constructing frequency distributions • COUNTIF function • HISTOGRAM function
=COUNTIF(A6:A134,1) =D4/D9*100
Histogram Function • Tools -Data Analysis-Histogram • Bins
The bins are the frequency categories
