50, 66, 73, 74, 75, 75, 76, 76, 81, 81
Remember, the range is when you subtract the lowest number from the highest number :)
Range : 81 - 50 = 31
Remember, the median is the middle number of an ordered data set from least to greatest.
Median : 75
Remember, the mode is the number that is on there the most.
Mode : 75, 76, 81 are all considered to be modes. However, if that is not one of the answer options, then your answer would be : There are not modes.
