    im at the university of Surrey apparently 4th top in england, and you just explained it 100 times better then what a £9000 a year tuition fee lecturer could explain it, thank you

      @djchilxxn 6 років тому +5

      I am a new math teacher, and I always think about this question. I try to do as best a job as I can, but when you have the pressure on, and a lot of eyes and ears focused on you, and you are trying to explain it in terms that everyone can understand, it isn't exactly the same situation. a lot less pressure filming a youtube video. that being said I love these videos and use them myself to buffer my knowledge and help me teach

    You are my savior. I'm using your videos to help me understand my statistics class right now. I don't understand my teacher because she has a very heavy accent and most of words I thoughtshe was talking about a different word, like for instance, scores she sounded like she is saying cigars. Later I realized she is talking about scores. i wasn't sure if I'm going tomget to get an A on this class. However, with the help of your videos, I believe I still have a chance to get an A. Thank you and thank you.

    I really like this video because it thoroughly explains the steps on how to find the standard deviation of a data set. It also showed me something new and that is to make a table when subtracting the data from the mean, it helps with the organization of the process.

      @CaptainSoftboy501 8 років тому +1

      Oh my gosh yes... Amen to that!!! Right now I feel like I just gave up and am just waiting it out in AP stats until I graduate XD we told our teacher that we didn't care if we didn't learn anything the rest of the semester so hopefully she takes us seriously and stops giving us work or at least tests, cause even with work she gives us the odd numbers and we just get the answers from the back. She says she doesn't care as long as her work gets done XD

    Sir.. thank you for giving time to this, a lot learn from you more than their professors teaching 2 hrs straight. Sir, may I ask from the formula part. How you got 1.58 and 1.41? I really don't have any idea. I really thought the second formula's answer is 0.50.
    Thank you in advance

    • @trixtao
      @trixtao 7 років тому +2

      Karl Lrak 1.58 because its the square root of 10/5-1 = 10/4 square root that and you get 1.58
      Same with the second formula.
      Always remember the square root.

  • @adinatapia305
    @adinatapia305 8 років тому

    Your video was extremely helpful but I have a few questions. So first of all what is n and how do you find it? Second is so when at the end you divide the numerator by the denominator do you have to put the square root onto the answer or would you just put the answer with the square root symbol around it?

    • @Edward-oe2yj
      @Edward-oe2yj 8 років тому

      n = the total number of data points, so there were 5 numbers used at the start as a "sample", so n=5
      The square root is part of the equation, so you will simplify the first one to √10/4 = √2.5 = 1.58

      @exceedingexpectations7962 9 років тому

      Abe Bust You haven't properly corrected her grammar. Her sentence is a run-on;therefore, punctuation must be correctly inserted, not just the apostrophe. It also appears she has abbreviated the word "videos," which I am intolerant to. "UA-cam," must also be capitalized since it's obviously a title. Here's the correct sentence. This may be more pleasing to read rather than that lackadaisical nonsense.
