Document Summary

There are 4 variables in the spss datafile. Using jdcc dataset, decide what variable you will use, and then; (a) set ho and h1, (b) run the analysis, (c) interpret the results. Dataset: juvenile defendants in criminal courts (juveniles charged with felonies in 40 states) Posthoc> select both bonferoni & tukey: h0= there is no diference in mean in groups of the independent variable. H1= there is statistically signiicant diference in mean in groups of the independent variables. The means are signiicantly diferent from each other in the independent variable. If it is less than . 05 it rejects the null hypothesis and retains the alternative hypothesis. Here, because the p value is . 000 which is less than . 05 that means there is statistically signiicant diference in mean in groups of the independent variables. The mean difference is significant at the 0. 05 level.
