Univariate Descriptors

Command: Math -> Univariate Statistics -> Univariate Descriptors...

In order to calculate the most basic univariate descriptors of some data set, you may issue the command Math/Univariate Statistics/Descriptors. After issuing this command, the data matrix is displayed in a numerical table.

 

You have first to mark all elements of the matrix which are to be included in the calculations. Then click Calculate Univariate Statitics to calculate the following descriptors:

  • number of selected data
  • sum of selected data
  • minimum value
  • maximum value
  • mean +/- confidence interval
  • standard deviation
  • variance
  • median and quartiles
  • skewness
  • kurtosis
These descriptors are calculated for both sets of marked data (type A and B, red and blue) and their logical combinations: A AND B, and A OR B.
