    I know it’s six years later but THANK YOU SO MUCH. I was ill when we covered this topic and now I’m reviewing it for homework and no one sent me notes so I’m currently doing my own. No textbook was able to make it as clear as you did. Thank you!!!!!

    Hi, since in this video the data started from 0, that's why you joined the curve from (0,0). But what about if the data started from 1 for example, do I start from (0,0) or (1,0) or from the first point plotted?

    @@alraydalley5635 For interquartile range you have to find the upper quartile and lower quartile and find the difference between them(UQ-LQ). To find the upper quartile you times the total frequency by 3/4 then plot it on the graph as if u were finding the median but instead finding the upper quartle, and for the lower quartile you do total frequency times 1/4 and plot on graph as previously.
