    For median you can just add the frequency together then do the formula n+1/2 using the total as n. Then whatever number you get you count how far into the table it goes for example it’s 5, it would be (for this table) 8 because that’s where the 5th number lies. :)

    thanks a lot for your help !
    solutions for last question-
    mode-13
    median - 13
    mean - 12.38 approx
    range - 3
    inter-range - 3
    i hope they are correct !

  • @JWelton
    @JWelton  11 лет назад +1

    Yes, that is a good method to figure out the median. If there are an even number this method will give you the number between them. If there are an odd number, it will give you the one exactly in the middle. Thanks for the suggestion.

    @missnyokaxo967 6 лет назад

    THANK YOU SOO MUCH😊. Firstly, I am in the 8 grade and I'm not really good at math so I found this very useful. My teacher isn't good at teaching math so this feels great to find someone who can. For years sometimes I felt like I have been struggling for not getting some terms in math... But because of you I can bump up my grades😁. Please continue to make these videos especially for the eighth graders going to highschool, this gives a thero teaching of how to do a frequency table including things you'll most likely be tested on!!! Btw thank you for leaving the "do it urself" kind of thing at the end, it really helps. (But you forgot to leave the answers😅)

  • @legomorriarty7583
    @legomorriarty7583 4 года назад +1

    How can the median be 7 in this case?
    While finding the median, you have to choose a figure that stands right in the middle of the row: 50% of figures should be lower and the rest 50% of them should be greater than the chosen figure.
    So the right answer here is 8.5.
    You can also apply the median-formula for even figures. Here: 1\2*(16\2+(16\2+1))=8.5

    if you have graphing calculator like ti-84, then just plug in those number. ur will be done in less than a minute.
    1. STAT-EDIT-ENTER
    2. PUT SCORE IN L1 LIST AND FREQUENCY IN L2 LIST.
    3. HIT STAT-CALC-(1:1-VAR STAT)-ENTER
    4. LIST: L1
    5. FREQLIST: L2
    NOW HIT CALCULATE
    THERE MEAN=
    STANDARD DEVIATION=
    SCROLL DOWN YOU WILL SEE M= (THIS IS MEDIAN) AND SO ON HERE

  • @JWelton
    @JWelton  11 лет назад

    If you mean the frequency is too large, I would still add up the frequency add 1 and divide by 2 to find the middle. Then you need to count up from the bottom or down from the top to that number.

    • @JWelton
      @JWelton  9 лет назад

      +Anna Wanstall I haven't seen a question like that. I would guess you could still get the midpoint between the highest number in the first quartile and the lowest number in the 2nd quartile and likewise between the 3rd and 4th. Then you could subtract for the interquartile range.

    Why did you divide 16 by 4 for the IQR? I don't quite understand where the 4 came from. Is it because it's the sq rt?

    • @JWelton
      @JWelton  10 лет назад +3

      Quartile means that it was divided into 4 parts. So 16 divided by 4 means that each of the quarters would have 4 numbers in it.
      Let's try another example. If there were 32 numbers, divide it by 4 and each of the quarters would have 8 numbers in it.

    • @JWelton
      @JWelton  9 лет назад
