i think i realized the equation for z score. z score= standard deviation divided by the mean of scores. if the standard deviation is higher than the mean, then ur z score will be positive. if the standard deviation is lower than the mean, then ur z score will be negative.

try it :)

why do all ur vids have the right speaker speaking only, can u get a better audio mic or recorder? hurts my ears cuz the audio is so bad.

@ongolos when I first started doing these vids I used an standard simple microphone. Now I use a nice microphone two channels (left and right) and all my videos are in high definition too. I a plan on redoing all the old videos.

ok.. i have the Z score, now what's the formula to figure out the area.

[statisticsfun]

@baker70romeo you look up the z score in the body of the "normalized table" in the back of your stats book. Watch the video I attached above called, "Normalized z score question for statistics" -- also I have a playlist called z scores.

Thank you so much for your time here. You did an excellent job of explaining the foundation so the rest can be more easily understood. Can you teach my stats prof (who is a rocket scientist) how to teach this stuff? Thanks again!!!!
