Upper limit of the 95% confidence interval of mean Where is the critical value of the Student's t-statistic with n-1 degrees of freedom Lower limit of the 95% confidence interval of mean Note: In OriginPro, has 4 more options, which are defined in the Variance Divisor of Moment branch. If there is no WEIGHT variable, the formula reduces to. Total number of data points, denoted by n Let be the th sample and be the th weight: The value in each cell specifies the weight of the corresponding data. Weighting Range The range that contains weighting information. So you can easily reorder the output columns. The grouping columns are set as categorical if most of the column values are text. You can add, remove, order grouping columns via controlling buttons: Move Up button, Move Down button, Remove button, Select All button, Select button in toolbar. Different grouping values indicate the data in the corresponding cells are from different groups. Statistical operations will be performed on each, independently.ĭata Range The input data range Group Multiple grouping columns contains grouping information can be inserted into the Group box. Specify the input data mode, indexed or raw.Įach column will be treated as separate dataset.
