Which histogram represents a distribution for a set of quiz scores where the quiz was very easy? (Choose one: Histogram I, Histogram II, Histogram III, or Histogram IV). 2.

Step 1

If the quiz was very easy, most students would score high. So, the histogram representing this situation would have a high frequency at the high score end. Without seeing the histograms, it's impossible to say which one it is. Show more…

00:01 We're given four different histograms here, and we want to connect them with some different scenarios.

00:09 So the first one we're given is which histogram represents a distribution for a set of quiz scores where the quiz is really easy.

00:18 So if we look at each of these, the first one looks like a pretty normalized distribution.

00:23 So that wouldn't make sense.

00:25 In terms of it being really easy, we would assume that more people would be getting it correct versus not.

00:29 The second one is possible, but it looks like it's skewed the wrong way.

00:34 Usually on the left hand side, it's like smaller values, not looking so good.

00:40 But the third one looks like a great opportunity where you see like all these high scores.

00:45 A few people maybe in like that middle range bs or cs, and then most people who are getting upper scores here.

00:51 So i think for number one, it goes along with histogram number three.

00:59 For the second problem says which histogram represents a distribution for the set of wrist circumferences measured in centimeters taken from the right wrist of a random sample of newborn female infants.

01:11 Well, this is, i mean, going to for sure be normalized.

01:15 I mean, you're talking about a large population of infants, totally random.

01:22 There's no way you could really track this.

01:23 So this one's going to be that first histogram there...
