Note: Some subtests do not have confidence intervals and will be denoted by a xx-xx as shown in the screenshot below. In addition, not all tests have a way to automate the calculation of confidence intervals, in that case manual entry of confidence intervals will be required if you want to include them in your report
PsychWriterPro includes the ability to automatically calculate confidence intervals on most data entry screens, but for some tests, manual entry of the intervals is required. When manual entry is required, we will validate that the interval is in the correct format to ensure accuracy in our calculations.
To ensure the best results, we recommend consulting the test manual or guidelines for the specific test being administered to determine the appropriate interval range. Our system will then use this range to calculate the confidence intervals for the test results.
To enter confidence intervals for a test that supports confidence intervals simply select the comparison group (age, grade, or both depending on the test) and also the Confidence intervals used (90% is the recommended)
Once you select the options required for confidence interval calculation, PsychWriter will automatically create a new column in the data entry to show you the confidence intervals.
