      this is kind of late but I was wondering how you got the standard deviation of baby height measurement is +/- 1.2 vs the standard deviation of adult heights of 8? How did we get the value of 1.2 and 8? I am not sure if I used the correct wording or if what I am asking make's sense but hope I can get an answer!

      @@santiagoramos1313 I just googled "average adult height" and found a table that listed the mean and standard deviation for the world and individual countries. I then did the same thing for babies. In other words, I didn't calculate those values, I just looked them up in a table.

  • @durgeshanand6774
    @durgeshanand6774 3 місяці тому

    I liked the explanation. Just one small thing i would like to add which many people might overlook.
    In real life situations, we do not draw the curve such that its width is defined by the std dev.
    Its the other way around. Like we just have data points from which we plot the curve. Then if its a curve satisfying these parameters discussed in the vid, we named it normal disrtibution. So , for example "Peak of the curve is given by avg" is not same as "peak of the curve happens to be the avg".
    Idk if i explained it properly but i jusy wanted to point out that the bell curve is not bound to follow these avg and std dev values, more like in this case of disrtibution, which we call as normal, the avg, std dev etc values fall in such that, say 95% of data is inside avg +- sigma width.
