Standard Deviation For Every "n" lines

Hello,

I found the standard deviation work around like here

Code:
awk '{x+=$2;y+=$2^2}END{print sqrt(y/NR-(x/NR)^2)}'

My task is to calculate Std. Dev for every 40 lines in a file that has more than 11000 records.

So I was wondering on how to edit the above formula such that I can get Std. Dev for every 40 lines.

I tried so many ways by including NR%40 and it still doesn't work.

Thanks

NAME
XmScrollVisible - A ScrolledWindow function that makes an invisible descendant of a ScrolledWindow work area visible SYNOPSIS
#include <Xm/ScrolledW.h> void XmScrollVisible (scrollw_widget, widget, left_right_margin, top_bottom_margin) Widget scrollw_widget; Widget widget; Dimension left_right_margin; Dimension top_bottom_margin; DESCRIPTION
XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function repositions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location rela- tive to the viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the ScrolledWindow widget be set to XmAUTOMATIC. Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant. Specifies the ID of the widget to be made visible. Specifies the margin to establish between the left or right edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved horizontally to make it visi- ble. Specifies the margin to establish between the top or bottom edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved vertically to make it visible. For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3X). SEE ALSO
