FTest_2Samp FTest_2Samp List1,List2[,Freq1[,Freq2[,Hypoth]]] FTest_2Samp List1,List2[,Freq1[,Freq2[,Hypoth]]] (Data list input) FTest_2Samp sx1,n1,sx2,n2[,Hypoth] FTest_2Samp sx1,n1,sx2,n2[,Hypoth] (Summary stats input) Performs a two-sample F test. A summary of results is stored in the stat.results variable. (See page 76.) Hypoth > 0 is Ha: s1 > s2 Hypoth = 0 is Ha: s1 ƒ s2 (default) Hypoth < 0 is Ha: s1 < s2 Output variable stat.F stat.PVal stat.dfNumer stat.dfDenom stat.sx1, stat.sx2 stat.x1_bar stat.x2_bar stat.n1, stat.n2 Description Calculated ó statistic for the data sequence. Least probability at which the null hypothesis can be rejected. numerator degrees of freedom = n1-1. denominator degrees of freedom = n2-1. Sample standard deviations of the data sequences in List 1 and List 2. Sample means of the data sequences in List 1 and List 2. Size of the samples. Func Func Block EndFunc Define a piecewise function: Template for creating a user-defined function. Block can be a single statement, a series of statements separated with the ":" character, or a series of statements on separate lines. The function can use the Return instruction to return a specific result. Note for entering the example: In the Calculator application on the handheld, you can enter multi-line definitions by pressing @ · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter. Result of graphing g(x) Catalog > Catalog > TI-Nspire™ Reference Guide 31
