This unit we learned about mean, median, and mode. We also learned when it is best to use these different measures of center. Ms. Bad calls them the 3 M's: mean (average), median, and mode. We also learned about 1st and 3rd quartiles, rang, and I.Q.R. To find these, put a set of data onto a number line IN ORDER, find the median, put all the numbers on the two sides of the median separated from each other, find the median of those, subtract the higher median from the other, and that's the I.Q.R. To find the range, find the highest and the lowest number in a data set, subtract the lowest from the highest, and that's the range. The first and third quartiles are the set of numbers that are on the left and right of the median (they will always be the same length). For the project, we made paper airplanes: the Dart, the Delta Wing, and the Huntington. We got a partner and chose the best two airplanes that we had. Then we measured how far the airplanes went. If it hit the wall at the end, A.T.! That stands for Awesome Tickles! No, it stands for Additional Testing. If we got A.T., we would go out into the hall to test it more because the hall is longer than the classroom. We determined that the airplane that traveled the most when thrown had an average distance of 297.8 inches!
