    And I'm just as confused as I was before watching this video. You keep using "standard deviation" to explain "standard deviation". But you never really explained WHAT a standard deviation IS. You might as well be explaining that the word "inch" is used to express how many "inches" something is without ever saying WHAT an inch IS.
    Yes, you said that it is used to determine how far from the mean a given example is. I get your point about how SD is used. But WHAT IS a standard deviation? How is "standard deviation" determined? What makes "1 standard deviation"?

    • @SteveFrenchWoodNStuff
      @SteveFrenchWoodNStuff 7 лет назад +123

      @0:38 here's where my problem lies. You tell what the standard deviation of this particular data set is ($28.01). But you didn't explain how that is determined. So it's just an arbitrary number you pulled out of the air as far as I can tell (given the lack of information). And that's why - even after watching a video entitled "Standard Deviation - Explained and Visualized" - I still have absolutely no clue WHAT an SD IS.

      Really? "Cause I still have no clue what a standard deviation IS, only that it's used to express how far a given sample deviates from the mean. But what determines HOW FAR from the mean equates to "a standard deviation" or "2 standard deviations", etc...? How is a unit of "standard deviation" defined?

    • @veritas785
      @veritas785 7 лет назад +2

      Standard deviation is more like "average distance of the points from the mean". A standard deviation is something you calculate first using the data set in hand, and then go on and see distance from the mean for each point.
      You can imagine, mean to be the centre of a circle and the standard deviation to be a radius.... this is the average distance of the points from the mean. For a normal distribution, meaning the values are more evenly distributed, 68% of the points fall within that radius. 95% of all the points fall within 2 x radius. 99.7% of the points fall within 3 x radius.
      You can call the standard deviation as the average deviation (from the mean), if you like. (I think the term average deviation may not be used because the formula for standard deviation uses squares and then square root, which doesn't sound like a real average).
      See other video from "MrNystrom" regarding standard deviation... that should really help.

      @LauraLovesHerCat 6 лет назад

      Not sure if I can answer your question fully, but I do have a little insight based on my personal and professional experience. I'll stick to the professional, though. A number of factors can make the traditional model of teaching (usually lecture-based) inefficient. Until we start to examine other means of curriculum presentation, we're really not doing anyone any favors, and I'd agree - the educational system is not working near its intended optimal standard.
      I can very much identify with this sentiment working in higher education over the last half decade, but Education as a whole is on a precipice, meaning we could strain in one direction or another. I think there are some brilliant minds and definitely some gifted people out there who can explain and are using available technologies to do so in a way we have not really seen before. I am hoping to see more videos like these, and I am hoping that more educators and others (instructional designers, educational technologists, all involved in this field) will embrace facilitator roles to better engage with content and media so as to best engage (and engage with) students to inspire an attitude of life-long learning in some areas. :) Long rant, I know, but your comment really struck me as being right on and the cry of the masses; I just hope I was able to offer a glimmer of hope!

    1:42, some elaboration on what he means by "statistically significant" or "expected variation". We consider some event which is under control can happen if its probability lies within 2 standard deviations on each side i.e., 95% probability in total. However if the event happens and it lies beyond 2 standard deviations i.e., 5% probability in total, we consider this event has happened purely due to chance and it is beyond control. Here in this example if what we are aiming for is,say, the quantity being filled in the bottle is 100ml and we get 95 ml once(which the customer does'nt mind) which falls inside 2 s.d , it is "expected variation". However, if we get a 90ml(which the customer does mind), and we find it lies within our 2 s.d too, the we consider the result statistically significant and try to control it since it not happening purely due to chance.
    I am assuming that our null hypothesis is "the event will not take place".
    Correct me if i am wrong : D

    I am still thoroughly confused as to how you obtained the SD of $28.01 for the values you used (21,50,62,85,90). I used several online standard deviation calculators and the answer given was $25.05, which is what I calculated. It would be extremely helpful if you would walk us through that rather than using a different value set as an example.

    • @mumiscrunk
      @mumiscrunk  4 года назад +1

      Hi there sorry for the confusion. There are two slightly different ways to calculate standard deviation based on whether you have all the data in the population (SD = $25.05) or are working with a sample of the data (SD = $28.01).

    In layman terms, mean is the average for the set of data (of one value to another) or it's also known as the expected value. Meanwhile variance is the average for the difference between the mean and each value from the set of data. And the square root of variance is known as standard deviation.

    • @AlexisAndersonAA
      @AlexisAndersonAA 5 лет назад +30

      Standard deviation =
      Start with finding sample variance...
      1. Sample Variance
      Take all data points and subtract the mean from each one, square it, and add the sum up
      ---> (21-61.6)^2 + (50-61.6)^2 + (62-61.6)^2+ (85-61.6)^2 + (90-61.6)^2 = 3137.2
      Divide the sum by the amount of data points (5) and subtract 1
      ---> 3137.2/ (5-1) = 784.3
      2. Standard deviation is the square root of the sample variance ...
      ---> root 784.3 = 28.005
      ~28.01
      hope that made sense :)

      @Alexis Anderso
      But why we subtract 1 from 5?

      Hasan Darwish that is just how the equation goes, subtract 1 from the total # of data points. Not sure of the actual logical reason behind it

      ​@@AlexisAndersonAA basically we do 1/(N-1) when we calculate std of sample of data and for whole population it would be simply 1/N.

    The sample standard deviation of the dataset 2,
    a, 12, 18, and 30 is 10.8 (correct upto one decimal place), where a is an unknown quantity. Then, the value of the sample variance of the new dataset that is obtained by adding 5 to each number of the given dataset is __________

    If you're complaining about the quality of this video in any fashion, then you desperately need a cold cocktail on a mild and sunny day on a tropical beach likely no more than 1.5x standard deviations from where you are right now as you read this silly comment. If you're not complaining about this video, I wish you the same. This video's producer made RUclips just a little bit better by adding it.

    Hello I’m watching this video a few years after it’s been posted. I have an observation regarding the units you provided for the example: $21, $50, $62, $85, and $90. When I went through the calculation the standard deviation comes out to 25.04. How did you reach 28.01?
