DESCRIPTIVESTATISTICS (AreaArray,GroupBy,ConfidenceLevelPercentage,KthLargest,KthSmallest,IsFirstRowLabels, NewTableFlag)


where,

  • is array of integers or reference to the cells containing array,
  • is a method that performs the analysis by Columns or Rows,
  • represents the confidence level for mean of data points and is between 0 to 100,
  • represents the Kth largest value for each range of data,
  • represents the Kth smallest value for each range of data,
  • is a logical value that determines if the first row has any label,
  • is a logical value that determines how the output should be displayed.

DESCRIPTIVESTATISTICS(), calculates a range of statistical measurements and summarises them into a table.

Description

DESCRIPTIVESTATISTICS (AreaArray,GroupBy,ConfidenceLevelPercentage,KthLargest,KthSmallest, IsFirstRowLabels,NewTableFlag)

  •   can be numbers or can be names, arrays or references containing numbers.
  • Values containing text, logical values or empty cells are ignored.
  • Argument   can be "Rows" or "Columns".
  • If   < '0' or   > '100', Calci displays an error message.
  • If   < '0' or   > 'Length of array', Calci displays an error message.
  •   can be a logical value TRUE or FALSE.
  •   can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be TRUE.
  • If   is TRUE, output is displayed on a new ZSpace cube. If   is FALSE, output is displayed on the same spreadsheet where command is written.
  • If data is invalid, Calci displays NaN error message.

ZOS

  • The syntax is to use this function in ZOS is  
  • For e.g., descriptivestatistics([[8,7,11,7,33],[8,8,11,18,37]],"columns",95,1,1,false,true)

Examples

Consider the following table with two arrays as input to DESCRIPTIVESTATISTICS() function -

Column1 Column2 Column3 Column4
Row1 8 8
Row2 7 8
Row3 11 11
Row4 7 18
Row5 33 37
Row6
=DESCRIPTIVESTATISTICS(A2:B6,"Columns",95,1,1,FALSE,TRUE)
=DESCRIPTIVESTATISTICS(A2:B6,"Rows",95,2,1,FALSE,TRUE)

DESCRIPTIVESTATISTICS() displays the respective output for above examples -
