Like a traditional Fix Pack, this modification release includes many quality improvements, but with the added benefit of those new additions. 


Statistical Procedures and Enhancements

Z-Tests and confidence intervals for Proportions and differences in Proportions: For One-Sample, Paired-Samples, Independent-Samples analyses.

Found under the Analyze > Compare Means menu, the new Proportions procedure allows users to test for differences in population proportions and construct confidence intervals on observed differences using a variety of methods for each type of analysis.

Reliability Analysis Enhancement: McDonald's Omega

As part of the Reliability procedure, McDonald's Omega allows users an alternative to the Cronbach’s Alpha statistic. To find this enhancement go to Analyze > Scale > Reliability Analysis, and under the Model dropdown on the Reliability Analysis dialog, select Omega.

Bivariate Correlation Enhancement: Added Confidence Intervals

This enhancement in SPSS Statistics is found in the dialog menu of Bivariate Correlations under the Confidence Intervals sub dialog. Users will be able to set the confidence interval parameter, apply the bias adjustment if desired for Pearson Correlation, and choose between various methods for other correlation coefficients.

Along with the new additions above we have also included confidence intervals for CONTRAST output in one-way ANOVA, added bootstrapping and multiple imputation to Proportions, and made an enhancement to multiple imputation predictive mean matching to enable the ability to choose the number of potential matching cases.


Usability Improvements

Session Management: Restore Points

This extension to the auto-recovery functionality introduced in SPSS Statistics allows users to save a point in time in their analysis that users can revert back to if needed later in the analysis, while still enabling the user to continue down the current analytic path. Session Management is found on the Welcome Dialog on the Restore Points tab next to the Recent Files and Sample Files tabs. On the Restore Points tab users will find both their Auto-Recovery files, as well as saved Restore Points.

Output Enhancements: Editor Experience

Several enhancements were introduced in SPSS Statistics for Chart Builder, as well as the Table & Chart Editors. These improvements decrease the number of clicks needed to get customizable output in the application by utilizing new toolbar additions and experiences.
