the mean (average) can be found by adding up all the numbers and dividing that by how many numbers there are. The mean of this data set is : 405/15 = 27
the mode is the number that appears most often in ur data set so the mode is : 15
the range is the highest number - the lowest number the range is (45 - 15) = 30
the median is ur middle number the median is : 24
ascending order (smallest to largest) is : mode, median, mean, range
Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
