Answer
mean=747.5,median=708,mode=627
Work Step by Step
You have the values:948,627,731,697,988,643,719,627.
To find the mean you have to add all the values up and divide by 8:$\frac{948+ 627+ 731+ 697+ 988+ 643+ 719+ 627}{8}$=$\frac{5980}{8}$=747.5
To find the median you have to arrange the values from the smallest to largest(627,627,643,697,719,731,948,988)You have two medians -697,719- you have to find the average which will be the median so $\frac{697+719}{2}$=$\frac{1416}{2}$=708
The mode is the number which occurs the most,627 repeats twice in this data set so it is the mode.
