Range and Mid-range

  • 0:00 - 0:05
    Find the range and the midrange of the following sets of numbers
  • 0:05 - 0:07
    So what the range tells us is essentially
  • 0:07 - 0:09
    how spread apart these numbers are
  • 0:09 - 0:10
    And the way that you calculate it is
  • 0:10 - 0:12
    You just take the difference between the
  • 0:12 - 0:15
    the largest of these numbers and the smallest
  • 0:15 - 0:16
    of these numbers
  • 0:16 - 0:17
    And so if we look at the largest
  • 0:17 - 0:18
    of these numbers
  • 0:18 - 0:21
    I'll circle it in magenta, it looks like it is 94
  • 0:21 - 0:23
    94 is larger than every other number here
  • 0:23 - 0:25
    So that's the largest of the numbers
  • 0:25 - 0:27
    And from that we want to subtract
  • 0:27 - 0:29
    the smallest of the numbers
  • 0:29 - 0:31
    And the smallest of the numbers in our set
  • 0:31 - 0:32
    right over here is 65
  • 0:32 - 0:34
    (Circled in green)
  • 0:34 - 0:36
    So you want to subtract 65 from 94
  • 0:36 - 0:38
    and this is equal to...
  • 0:38 - 0:41
    if this was 95 minus 65, it would be 30
  • 0:41 - 0:43
    94 is one less than 95
  • 0:43 - 0:44
    so it is 29
  • 0:44 - 0:48
    So the larger this number is that means the more spread out the larger the
  • 0:48 - 0:51
    difference between the largest and the smallest number
  • 0:51 - 0:54
    the smaller this is, that means, the [tighter?]
  • 0:54 - 0:59
    the range [just to use the word itself?] of the numbers actually are, so that's the range
  • 0:59 - 1:02
    the midrange is one way of thinking
  • 1:02 - 1:05
    to some degree of kind of central tendency, so midrange,
  • 1:05 - 1:10
    midrange, and would you do with the midrange is to take the average
  • 1:10 - 1:13
    of the largest number and the smallest number
  • 1:13 - 1:18
    so, here we took the difference that's the range. The midrange would be the average of this two numbers
  • 1:18 - 1:27
    so 94 plus 65 when we talk about average and [talk about] arithmetic mean over 2 so this is going to be what...
  • 1:27 - 1:33
    90 plus 60 is 150, 150 plus...
  • 1:33 - 1:40
    4 plus 5 is 159, 159 divided by 2 is equal to
  • 1:40 - 1:45
    150 divided by 2, is 75, 9 divided by 2 is 4.5,
  • 1:45 - 1:50
    so this would be 79.5
  • 1:50 - 1:53
    so is one kind [of way?] of thinking about the middle of these numbers,
  • 1:53 - 1:58
    another way is obviously the arithmetical mean we [] to take []
  • 1:58 - 2:00
    obviously you can also look at things as the median and the mode
  • 2:00 - 2:03
    so range and midrange
