    By far the most intuitive explanation I've come across on density curves. Thank you

    I'm self studying AP Stats

      Lucas M Good thing stats is not as difficult as something like AP calc BC.

      Hey, I just took that class. I got a 5.
      I don't know what to say about Stats. I'm kind of scared. Interpreting results. Planning experiments. I'm trying to get a head start over the summer.

    We need to combine stats with calc. No silly rectangles.

      Maybe can you be specific in which way you would want a video to this specific request.

    Great videos! Only the segway from the first two charts to the next chart at 2:55 is a bit misleading, as the bars should indeed get lower if their hight is supposed to describe the percentage of the data in the respective width range of the bar. Instead of the hight of the bar, it should be the area of the bar that describes this percentage.
    In addition, it would be useful to explain the density curve as the derivative of the cumulative relative frequency graph.

    I'm guessing this is the latest addition to the probability course? This is a great way to segue from the probability mass functions of discrete measurements to the probability density functions of continuous measurements that I've never seen anyone else use as an explanation.

    Thanks. Now I know what is purpose of density curve

    Hi, I am not clear this, if we have no items in a range of x => the y should be 0 in that range. It will not be the continuous line graph, right?

    I believe that the final explanation of the areas explaining the % of data is unclear. Doing the same example in a less granulated graph doesn't bring the expected results.

    This is what's called kernel density plot, right?

    There is a possibility to drink exactly 3 glasses. Some people might drink 4.235757846754916456368795164576510 glasses of water. Someone might be "lucky" enough to hit exactly 3. I might be wrong, but that's what I think.

    Guys, I need help!!!
    How to find the area under the curve?? Like In the video he told that area under 2 to 4 is 40%... how did we get this 40%?

    • @isavenewspapers8890
      @isavenewspapers8890 5 месяцев назад

      It was just an estimate. For a precise answer, you would use something called an integral, which is a concept from calculus.

    I wonder how to drink 0.7 or 8.1 glass of water!

    • @isavenewspapers8890
      @isavenewspapers8890 5 месяцев назад

      To be more precise, let's say that "one glass of water" is an amount of water with a volume of exactly one metric cup, or 250 mL. Then 0.7 of a glass of water is 175 mL of water, and 8.1 glasses of water is 2,025 mL of water.

    People should stop bitching their professors to whom they failed to concentrate or just failed to score the bounty that would had lead them to better professors.
