    Nice explanation. I am looking for exact meaning of standard deviation. Very useful, I am studying 3rd year MBBS, I am looking for this topic which is coming under Biostatistics of Community Medicine.

    Just came across this. Maybe someone has already mentioned it but the absolute value for Abdul is incorrect. Abdul has a score of 73 and the average is 70 making the absolute value of Abdul's score minus the average 3 not 2. Disappointing that the work was not checked before publication. Stopped watching at 3:33.

    5:31 if i add few more person with 70 mark then even stander deviation again become near to mean deviation so how it is full proof concept thus in that case variablity is compare by coefficient of variance

    Thank you very well explained and easy to follow;
    I think when that famous man was once quoted in saying "if you can't explain something in simple form maybe you don't understand it yourself" he was thinking of you. Good simple explanation ! ps: that was Einstein
    I precision shoot rifles and the SD now is a big issue and discussed when collecting an array of numbers.
    Only question I ask now is when someone says the SD is very low for a set of target hole variations calculations I ask compared to what ? No-one has an answer for that.

    Hi @codebasics. Very nice explanation about MAD and SD. What happens if we use SD when the data is not normally distributed. At 7.33 minutes it states that using SD has nice properties. What are those nice properties?. A step-by-step method on when to use SD and when to use MAD on data points will be helpful. Thank you :)

    How can I find mean and variance of probability distribution using python? I have mentioned a problem below. Thanks in advance!
    The number of times I go to the gym in weekdays, are given below along with its
    associated probability:
    x = 0, 1, 2, 3, 4, 5
    f(x) = 0.09, 0.15, 0.40, 0.25, 0.10, 0.01
    Calculate the mean no. of workouts in a week. Also evaluate the variance involved in
    it.

    Thanks so much for this video, it made the concept a lot clearer. I do have a question however, I don't know if I'm miscalculating but for the 4th table, wouldn't the score avg. be 71, which would change the MAD to 4? Because if you add up the scores (83+70+70+63+70+70), you get 426, divided by 6 (number of students), it's 71. Right?? Or am I missing something? And then for the abs. column it would change to: 12, 1, 1, 8, 1, 1; that totals 24. 24 : 6 = 4 for our MAD. Could somebody verify this or explain where my logic is off please?
