Since you dont have the data you cant calculate the exact values to get this answer. Add them together then divide by two. Whats the order of the values from left to right.
Find the range and calculate standard deviation to compare and evaluate variability of data sets.
Be sure to arrange the numbers by their numerical value. The mean for this group is 291000 the median is 160000 and the mode is 75000. While the mean and median require some calculations a mode value can be found simply by counting the number of times each value occurs. If there are 2 numbers in the middle the median is the average of those 2 numbers.
