You have the values 11,12,12,12,12,12,12,12,12,12,12,12,12,12,12,13,13. To find the mean add all the values and divide by 17(number of values):$\frac{11,12,12,12,12,12,12,12,12,12,12,12,12,12,12,13,13}{17}$=$\frac{205}{17}$=12.06 To find the median arrange the values from least to greatest and find the middle value:11,12,12,12,12,12,12,12,12,12,12,12,12,12,12,13,13.The median is 12. The mode is the value which occurs most often. The value 12 occurs 14 times so it is the mode. The range is the difference between the largest and smallest value:13-11=2. The range is 2. Mean is 12.06. Median is 12. Mode is 12. Range is 2
