Best ResponseYou've already chosen the best response.0Good so now, look at each answer above an ask yourself whether an outlier would affect it. You will need to know how each of the answers a) b) c) and d) are defined and calculated

Best ResponseYou've already chosen the best response.0an outlier is a data point that's far away from the other data. It has to be 1.5 times the IQR away from the nearest data point. Like if the test scores of a class were 10, 75, 76, 81, and 90, the 10 is an obvious outlier. So outliers affect the range and mean for sure

Best ResponseYou've already chosen the best response.0standard deviation is a measure of how far the data points are away from the mean, so a large or small outlier can screw with it

Best ResponseYou've already chosen the best response.0they're asking you about 133. All the other numbers are in the 50s and 60s. That means 133 is far away from everything else. What's that called?
