st095 Shape of distributions

  • 0:00 - 0:05
    When we create this histogram and choose our bin size, we sometimes sacrifice
  • 0:05 - 0:09
    detail for convenience. It's very convenient to look at this histogram and see
  • 0:09 - 0:14
    the shape, and it does tell us something about the data, but sometimes we can't
  • 0:14 - 0:19
    know all the little details just from this. Remember that we cold have a
  • 0:19 - 0:24
    histogram with bin size of one, but that might not show us the shape of the data
  • 0:24 - 0:29
    as well as having a histogram with a larger bin size. The shape of distributions
  • 0:29 - 0:35
    is really important. We're going to be looking at shapes throughout the rest of
  • 0:35 - 0:40
    this class, but it's also really important in your daily lives, when you're
  • 0:40 - 0:45
    listening to the news, or looking at research, and making decisions, you need to
  • 0:45 - 0:50
    know about the shape of data in order to draw sound conclusions. So from here on
  • 0:50 - 0:55
    out, frequency distributions is going to be a big part of the class.
