This is the full calcSD calculator. This is mostly just for testing. It's a bit more complex than the normal version and has a lot more data. Know what you're doing and don't get too attached to the statistics.
Average (SD): The average/mean of the selected study, also its standard deviation.
In a room of n: How many would be bigger than you in a room of n guys other than you. You can enter a custom value in the OTHER box. Values above 10 thousand not recommended, and values above 100 million are not allowed.
Z-Score: How many standard deviations you are above (or below if negative) the average/mean. Also known as standard score.
Classification: Classification based on the Z-Score for each measurement. If you're looking for an overall classification, look at the volume one.
Times the avg. size: How many times bigger than the average you are.
Other - Fl. Volume: Shows the flaccid volume. No, I'm not doing percentiles for this, don't even ask.
*Other - Diameter: Shows you your approximate diamater (depth and/or width). This assumes the width and the depth are the same, which they probably aren't.
Other - L/F Ratio: Shows the erect length to flaccid length ratio for the grower/shower classification.
Other - V/F Ratio: Shows the erect volume to flaccid volume ratio for the grower/shower classification.
