Despite being "old", the command is still very valuable and keeps some options not available in GLM (including allowance of fractional case weights). In SPSS, there exists, besides GLM, also and older procedure MANOVA - now available only through syntax, not menu. The p-values for those will be displayed in an additional table of the output. Tuy nhiên, trong phm vi tài liu này chúng ta ch nói ti phng pháp ANOVA 1. ANOVA có 3 phng pháp: ANOVA 1 chiu, ANOVA 2 chiu và MANOVA. Phng pháp này giúp chúng ta so sánh tr trung bình ca 2 nhóm tr lên. 05, then there is a statistically significant difference between the two independent groups identified in the (I) Group and (J) Group columns. The data are those that appear in Table 17-3 of Howell’s Fundamental statistics for the behavioral sciences (7th ed.) and in Table 13.2 of Howell’s Statistical methods for psychology (7th ed.). Note that using syntax of GLM command, specifically LMATRIX subcommand, you can request different ways to recode factors internally into various types of contrast variables. ANOVA giúp chúng ta gii quyt tr ngi ca Independent Sample T-Test. The steps for interpreting the SPSS output for post hoc tests with ANOVA In the Multiple Comparisons table, look under the Sig. ANOVA2-SPSS Two-Way Independent Samples ANOVA with SPSS Obtain the file ANOVA2.SAV from my SPSS Data page. Parameters table always correspond to regressional, type III SS, reckoning of sums-of-squares, but ANOVA table could reflect also other reckoning (such as type I or II or IV SS) which will add to the discrepancy of p-values. These variables have been measured on the same cases. Compare the p-values with those from parameter estimates table. SPSS Repeated measures ANOVA is a procedure for testing whether the means of 3 or more metric variables are equal. Likewise, recode your factor(s) into dummy variables (codes 1, 0) and perform linear regression. Compare the p-values with those from ANOVA table. Then recode your factor(s) into deviation variables (codes 1, 0, -1) and perform linear regression with them. The following important statistical procedures are covered in the course: 1) One-way between ANOVA. dummy variables) contrast coding of the factors. This course covers - step by step - a number of different ANOVAs and related statistical tests in SPSS. Parameters table corresponds to indicator (i.e. ANOVA table always corresponds to deviation contrast coding of the factors. ANOVA, MANOVA, etc.) with categorical predictors (factors) specified, the p-values discrepancy observed for the factors between the ANOVA-table and the parameter estimates table has this reason. In SPSS General Linear Models procedure (GLM: i.e.
