Basic statistical methods

These basic functions allow you to compare observations recorded at two points in time, and analyze the personality of your data. These few statistical tests are sufficient to analyze and present your results in a meaningful way. 

Each of these statistical methods can be performed with Excel or SPSS or any statistical software package.  These online utilities provide alternate resources for those who do not have access to a statistical software package.  

Greg Vinson’s webinar “Demonstrating Client Improvement to Yourself and Others: Understanding and Using your Outcome Evaluation System” explains the meaning of each of these functions, and demonstrates how to perform them within Excel.
