Best ResponseYou've already chosen the best response.3First sort the numbers from smallest to biggest 12, 12.2, 12.3, 12.6, 12.8, 12.8, 13.5, 13.9, 14, 14.2 which is the middlemost number?

Best ResponseYou've already chosen the best response.0The middle most number would be 12.8

Best ResponseYou've already chosen the best response.3correct, that's the median notice how there is a line over the 12.8 and this line corresponds to the median since it's in the inside of the box that means Jack has the right median and plotted it correctly

Best ResponseYou've already chosen the best response.3focus on the first half (ie first 5 values) 12, 12.2, 12.3, 12.6, 12.8 what is the median here?

Best ResponseYou've already chosen the best response.3good this is where Jack messes up because he placed the left edge of the box over 12.5 when it should be over 12.3

Best ResponseYou've already chosen the best response.0The median would be 13.9

Best ResponseYou've already chosen the best response.3so that is Q3 Jack marked that value correctly since the right edge of the box is over 13.9

Best ResponseYou've already chosen the best response.3and finally, the min is indeed 12 since that is the smallest number so Jack plotted the min correctly as well
