Asking questions about data in a graph

  • 0:00 - 0:02
    - [Instructor] We're told the
    students in Mr. Diego's class
  • 0:02 - 0:05
    explored different art mediums.
  • 0:05 - 0:10
    Afterwards they shared which
    art medium was their favorite.
  • 0:10 - 0:11
    So here it says favorite art medium,
  • 0:11 - 0:15
    so that's the title of
    this bar graph here.
  • 0:15 - 0:19
    And they give us the different mediums.
  • 0:19 - 0:21
    Is it media or mediums?
  • 0:21 - 0:24
    Well, they tell us the
    different media mediums
  • 0:24 - 0:26
    that they're using to construct the art.
  • 0:26 - 0:29
    A medium is just what type of material
  • 0:29 - 0:30
    are you using to produce that art?
  • 0:30 - 0:31
    So painting, you're using paint.
  • 0:31 - 0:33
    Drawing, you're using pencil and paper.
  • 0:33 - 0:35
    Sculpting, some type of clay.
  • 0:35 - 0:36
    Collage, you're cutting things up
  • 0:36 - 0:37
    and you're gluing it together
  • 0:37 - 0:39
    and in a mixed way.
  • 0:39 - 0:40
    And then on the vertical,
  • 0:40 - 0:41
    going up and down here,
  • 0:41 - 0:43
    we see the number of students.
  • 0:43 - 0:45
    So each of these lines right over here,
  • 0:45 - 0:47
    we increase by one.
  • 0:47 - 0:50
    So the scale, sometimes
    you'll hear that word is one.
  • 0:50 - 0:51
    You'll definitely see other graphs
  • 0:51 - 0:53
    where every time you go up by a line
  • 0:53 - 0:55
    you're actually going by two or four,
  • 0:55 - 0:56
    some other numbers.
  • 0:56 - 0:58
    So it's very important
    to keep track of that.
  • 0:58 - 1:00
    But now let's look at the question.
  • 1:00 - 1:02
    Which questions can be answered
  • 1:02 - 1:06
    using the scale of this graph.
  • 1:06 - 1:08
    Alright, it tells us to pick two answers.
  • 1:08 - 1:10
    So why don't you read
    these and pause the video
  • 1:10 - 1:13
    and try to answer this
    before I do it with you.
  • 1:13 - 1:14
    Okay, let's do it together.
  • 1:14 - 1:16
    So let's see if this one
    is something we can answer.
  • 1:16 - 1:18
    How many students chose collage
  • 1:18 - 1:20
    as their favorite art medium?
  • 1:20 - 1:22
    Well, we can see very clearly
  • 1:22 - 1:24
    if we look at the art medium collage
  • 1:24 - 1:29
    that exactly seven students
    chose that art medium,
  • 1:29 - 1:31
    so I can definitely answer that question.
  • 1:31 - 1:35
    Why do students like drawing the most?
  • 1:35 - 1:36
    Well, this doesn't tell me anything
  • 1:36 - 1:38
    about why students like drawing.
  • 1:38 - 1:42
    They just say which art medium they liked
  • 1:42 - 1:44
    or is their favorite.
  • 1:44 - 1:46
    And drawing is, it does seem to be the one
  • 1:46 - 1:49
    that the most students wanted to use,
  • 1:49 - 1:51
    but it doesn't say why they like them,
  • 1:51 - 1:53
    so I'm just going to rule this one out.
  • 1:53 - 1:54
    I'm guessing I'm going to pick this one
  • 1:54 - 1:56
    cuz I need to pick two, but let me see.
  • 1:56 - 2:00
    How many more students chose
    painting than sculpting?
  • 2:00 - 2:02
    Well, we can see that
  • 2:02 - 2:04
    painting has eight students,
  • 2:04 - 2:07
    sculpting has six students.
  • 2:07 - 2:09
    And the difference over here,
  • 2:09 - 2:12
    this is two between
    painting and sculpting,
  • 2:12 - 2:14
    so we can definitely answer that as well.
