Best answer

given set  is   213  157  171  142  155  157

rewrite the above set in ascending order   142  155  157  157  171  213

Median is the arithmetic mean of two middle most numbers = (157+157)/2 = 157

mean is the ratio between sum of the total numbers and total given numbers

mean=142+155+157+157+171+213 /6

mean=995/6

mean=165.833

mode is the most repeated numbers in the set

mode=157

rang is the difference between highest and least numbers in the set

range =213-142

range  = 71
