1 you already know it’s 8.35
2. Mean=11.7 (add them all together and dived by how many numbers there are in this case 9)
median=14 (put all numbers in order from least to greatest and find the middle one) I.e (2,6,9,10,->14<-15,15,16,19)
mode=15 (the number that appears the most)
Range=14 (the distance between the highest and lowest number)
Hope I’ve been helpful (this took way to long to make)
