Statistical Analysis of Sampled Data
Up to 200 sampled values can be entered or imported into the data table.  The data entry table changes depending upon which data sample option has been selected.
 
The Data Import Profile Screen, which is accessed by selecting the Import option on the menu, can be used to import data directly into the Measurement Results table from the following external application files: Microsoft Access, dBASE III or IV, Microsoft Excel 3.0 through 2000, Lotus 1-2-3 WK1 through WK4, HTML and delimited text files.   

Data Sample Options
The Enter Individual Values option is selected when entering individual repeat measurements.  The data can be entered as measured values or deviations from the nominal or specified value of the parameter. 
 
The Enter Sample Means option is selected when entering mean values obtained from sets of repeat measurements.  The mean values or deviations from the parameter nominal value are entered along with the standard deviation and sample size for each set of repeat measurements.  
 
Computed Statistics
The computed statistics vary slightly depending upon which Data Sample Option has been chosen. The computed statistics for both options include the Mean Value, Sample Size and Std. Uncertainty. The user can input a Confidence Level (%) or Coverage Factor to compute the Exp. Uncertainty. 
 
The Use Uncertainty in the Mean option box is checked if the uncertainty is to be reported for the mean value (or overall mean for the sampled mean values option).  If this option box is left unchecked, then the standard uncertainty applies to individual measured values 
 
Correction Factors
If a bias (i.e., systematic offset) from the parameter's nominal value has been input via the Parameter Bias Uncertainty Worksheet, then the user can select whether or not to include the Bias Correction factor to the computed mean value.
 
A fixed offset in the subject (or measuring) parameter value or reading can also result from environmental factors (e.g., temperature, humidity, air pressure, ...).  The user can select whether or not to adjust the computed mean value by an Environmental Correction.  The environmental correction is estimated using the Measuring Environment Uncertainty Worksheet, which is accessed via the Environmental Factors button on the Main Screen Error Source List.
