وقتی از آنها به خوبی استفاده شد ، نمودارها می توانند به ما بطور شهودی داده های پیچیده را درک کنیم. اما از آنجا که نرم افزار بصری استفاده بیشتر از نمودارها را در کلیه رسانه ها امکان پذیر کرده است ، همچنین استفاده از آنها را به روشی بی احتیاط یا نامشخص آسان تر کرده است – و همانطور که معلوم می شود ، روش های زیادی وجود دارد که گراف ها می توانند گمراه کننده و آشکارا دستکاری کنند. Lea Gaslowitz با چیزهایی مشترک است که باید به دنبال آن باشید.

  1. There is an add in this video from "Frontier" practicing the exact what this video trying to tell, about context of graph.
    Data can be customed in its presentation according to framed context.
    Manipulation of operands change the number.

    Gin,

  2. I want to use this video for class but the end (man sitting at the bar with alcohol in front of him) isn't appropriate for school aged. Great content. Wish I could share it.

  3. I think the first example of the chevy exaggerating their graph was not appropriate, because it was about the rate of durablity of their trucks. Surely, they exaggerated the graph, arguing theirs are the best. But it doesn't mean that the mere percents of difference doesn't matter. Assuming it was the rate of trucks broken, we can say toyota trucks almost doubled chevy in loss.

    I think it's almost like a fielding rate of fielders in baseball. Between 96% and 98% seems small difference, but it says the 96% one commited twice more errors than the other.

  4. A good book to read is How To Lie With Statistics by Darrell Huff. An old book but still relevant. There is another book used in an Uol Stats undergrad course but I can not for the life of me remember its name. It is lost in my room under some clothes or books.

  5. So we're all gonna ignore the fact that the guy saw the graph at the bar, examined it so intently that his eyes fell out and then married it? Is this some kind of subliminal relationship advice?

  6. In France, a major TV news channel showed a pie graph with 47% of people not supporting a march against a new labour law… with 2/3 of the graph colored. The title was: "The majority of French don't approve this march".
    and they showed 32% approved the march with roughly 1/3 (which is honnest) and the 21% "without opinion" was a tiny slice.
