[Video] Q51: According to figure 1, which of the following is closest to the mean number of aggressive interactions initiated in pairs of red-headed finches in a 30-minute period?

Explanation for Question 51 From the Reading Section on the 2018 April Sat

Hey guys. So question 51 says, 2 according to figure one, which of the following is closest the mean number of 3 aggressive interactions initiated in pairs of redheaded finches in a 30 minute period. 4 So when they say a bunch of words at once, 5 it might be a little overwhelming, but all we need to do for this 6 one, it's just go back, analyze figure one. So let's go back to that 7 one and look at the mean number of aggressive interactions for pairs of redheaded 8 finches figure what number one is here. 9 Now this says for the redheaded pairs, this is all within the 30 minute 10 window. It looks to be that their mean number of aggressive interactions is like 11 a little over two. That seems that's the average. 12 So a little bit over two. So let's see whichever answer choice over this 13 one. Um, falls in line with that says, 14 which of the following is closest to the mean number of aggressive interactions? 15 Well, it's not close to 0.5. It's not close to one. 16 It's not close to 1.5. It's closest to two based on a proper reading 17 of figure one. So that's all we need to do for this.
