Origin provides tools for user to generate basic statistics for rows in worksheet.
In this blog post we will discuss the tools to generate row-wise statistics:
- Using the “Statistics on Rows” menu
- Rowstats x-function for non-contiguous data/multiple sheet
- Pros and cons of the two methods
Using the “Statistics on Rows” menu
To generate the basic statistics row by row, choose menu Statistics> Descriptive Statistics> Statistics on Rows.
The dialog provides over 30 options and interactive GUI for user to calculate descriptive statistics on rows for contiguous data
Statistics on rows for non-contiguous data/Multiple Sheet
While the Statistics on Rows menu provides advanced settings and interactive GUI to user, there is another quick way, rowstats, which enables to get row-wise statistics for more flexible input data range. The rowstats x-function supports seven outputs
- Mean
- Standard Deviation (SD)
- Standard Error of Mean (SE)
- Minimum
- Maximum
- Number of Points
- Sum
CASE-1. Statistics on rows for non-contiguous data
Sometimes the data are stored in non-contiguous columns, or non-contiguous rows. The rowstats x-function can help to generate row-wise statistics on selected ranges.
- Open the Script Window from Window: Script Window menu
- Press Ctrl key to select non-contiguous ranges in worksheet
- Type the following in the Script Window, then press Enter:
1rowstats - The row-wise statistics for selected range will be generated in the columns next to the input column
CASE-2. Statistics on rows from multiple sheet
If the data are stored in different worksheet/workbook and you want to create a new workbook for the statistics on each row of certain columns, you can also use the rowstats x-function.
- Prepare a worksheet to store the results
- Open the Script Window from Window: Script Window menu
- Type the following in the Script Window, then press Enter:
1rowstats -d
- In the opened dialog, click the Triangle button to the right of Input. Choose Select Columns… from the context menu to specify columns in different sheet in the Column Browser.
- Click Interactive button to the right of desired outputs, now which are Mean and Standard Deviation. And select columns in the prepared worksheet.
