Here are 10 test scores: 30, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 74. Does this set have an outlier and, if so, how does removing it affect the mean?

you find mean by adding up all the numers then dividing them by how many numbers there are. the outlier is 30 if you take that away the mean would be 78.8 ,
