Best ResponseYou've already chosen the best response.0ok, so as you can see there is a greater amount of numbers along the 350 range than the 300 range, so since there are more on the higher numbers, it would be skewed to the right. Can you see that?

Best ResponseYou've already chosen the best response.0skew refers to how the mean is affected, not the greater amount of data.

Best ResponseYou've already chosen the best response.0i think youll find if you calculate the mean, it will lean heavier towards the side of greater data which is what we are seeing in this situation. I could be wrong but that is just my understanding

Best ResponseYou've already chosen the best response.0if we tilt this on its side ... you see that the 30s are smaller than the 35s the 30s are pulling the mean away from the greater portion of the data

Best ResponseYou've already chosen the best response.0But doesnt the fact that the question specifically asks for a bar graph not a normal distribution, affect the way this turns out? now you got me wondering haha

Best ResponseYou've already chosen the best response.0the stem and leaf can be viewed as a crude histogram .. the length of the leafing parts gives us a rough shape.

Best ResponseYou've already chosen the best response.0In paint? Alrighty. I usually do it in word but of course you can't save it as a picture so that doesnt work.

Best ResponseYou've already chosen the best response.0jeweaver, i think your bar graph is a little off ... not sure how you worked density versus the other thing

Best ResponseYou've already chosen the best response.0i honestly through the data points into my calculator and told it to make me a histogram of the data, and then based the data on density of occurrence, thats all, the information on the left isnt really significant
