  • Does this data seems to be valid?

    I'm doing some charts in excel that shows in which percentile you're in (length,girth,volume).
    I'm taking my data from mraverage.com
    Doesn't the numbers seems to be on the lower side?

    5,50 24,00
    5,75 48,30
    6,00 72,20
    6,25 81,50
    6,50 88,20
    6,75 92,60
    7,00 95,50
    7,25 97,50
    7,50 98,40
    7,75 99,20
    8,00 99,50
    8,25 99,80

    Is a 8 bpel really in the 99.5th percentile?
    And if you have 6,00 bpel you're in the 72.20th percentile.

    The numbers from 6" up seem skewed, 7" was I thought about the 90% not 95, thought 8" was about 98%.
    What study is this based on? The % between 6 and 7.25 seem particularly out.
    Accuracy would tend to diminish after 8" due to lack of numbers.

    Your idea is good gyrta.

      I'm taking the data from Mr. Average - The true story about penis size, from a site that isn't trying to sell you anything.
      And the data is from Lifestyles Condom, 2001.

      When calculating the percentile for 6" I'm adding the percent for "5,75-6.00" with percent for all the lower data. By this I know how many percent have up to 6" or lower.
      Am I interpreting the data wrong?

      I've done a graph showing volume/percentile.

      Volume for a (7*5.5) is 18ci and he'll be 93rd %-ile.
      7" is ~95th %-ile accordig to the survey and 5.5" is ~92nd %-ile.

      Volume for a (8*6) is 22.91ci and he'll be almost on the 99th %-ile.
      8" is 98.90th %-ile and 6" is in the 98.89th %-ile.

        This doesnt seem right to me, but then what is there to base it on. I doubt theres been an accurate penis survey yet.

        If you were to survey pegym members you'd get a very different story!!!

          Pegasus, I did also thought that 7" was in the 90th %-ile and 8" in the 98th %-ile, but I can't find data that backs it up.
          Wikipedia also use lifstyle as data source and provide this chart:
          File:Penis percentile.svg - Wikipedia, the free encyclopedia

          I've done a chart for length based on the same data. (see attachment).
          The chart is equivalent to one from wikipedia, both uses the same data. So I've probably interpret the data correct.

            The fact that it does not include micropenis, that is 3.5 to 5 inches skews the data.
            Start 2009/06/24 bpel 5.5 eg 4.75
            2009/08/26 bpel 5.5 eg 5.25
            2010/01/05 bpel 6.12"
            2010/08/01 bpel 6.25
            Goal 7"

              As far as I am aware, the LifeStyles condom survey from Cancun was never published so the methodology was never completely clarified. I have seen people debate whether the length data reflected bone-pressed measurements, non bone-pressed measurements, or something in between. A condom manufacturer would seem likely to be more interested in non bone-pressed measurements. My guess is that the data is more relfective of NBPEL than BPEL.

              Another factor that should be taken into consideration with this survey was that the guys had been asked to volunteer at a night club. It is possible that alcohol had an influence on the data, and if it did, it would seem more likely to have skewed the average length downward. On the other hand, out of a total of 400 volunteers, 101 alledgedly couldn't achieve an erection to allow measurements, a percentage greater than 25%. It is quite possible that those volunteers who felt more modestly proportioned used that convenient excuse to opt out of the measurement process, which would have skewed the length data in the opposite direction.

                Yes, you're right about the nbpel.
                If so, the data seems to be more reasonable.

                  But then nbpel is not an accurate measurment.
                  It is possible, that as the Cancun study was not selfmeasured, whereas most other studies were, that this study is just more accurate.
                  Amongst studies with some cred ,there seems to be some agreement around a little under 6 by 5, from memory the Cancun study came out a fraction less than most.

                    I just want to be able to tell people that my cock is in the 90th percentile in length and girth. I've never been in the 90th percentile for anything, so dick size would be a good start

                      The LifeStyles study was not a self-measured, self-reported study. The measurements were taken by 2 nurses supervised by one physician. Every self-reported study has shown averages for length and girth (especially length) well above those in which measurements were taken by a second party.

                        Yes redbear,so as I said it may just be more accurate.
                        However it is interesting that it has a similar result for average size, but finds dicks over 6.5" length less common.

                          But since lifestyle is a condom-maker I can't see why they want to measure bpel, they should be more interested in nbpel.
                          Let's say the the measurement is taken in nbpel and we add about 0.5", then the data makes more sense.

                            Well that makes sense I suppose.
                            Has anyone read the protocol used?

                              I'd like to see the original report. Was it published somewhere reputable in a medical or scientific journal?
