**interpret the results for you:**

### Interpreting the KS Test Results

For each significance level from 0.2 to 0.01, QI Macros template tells you (in column H) if you should reject the null hypothesis or cannot reject the null hypothesis that the cumulative sample function matches the cumulative probability function.

**Note: **Excel doesn't have the ability to do statistical tests of non-normal (i.e., not "bell shaped") data. QI Macros adds this functionality with a set of templates to handle non-parametric data.
