Q. Select the outlier in the data set.6,55,61,65,66,68,74,84
Identify Data Set: Identify the data set and understand what an outlier is.An outlier is a data point that is significantly different from the rest of the data. It can be much higher or much lower than the other values in the data set.Data set: 6,55,61,65,66,68,74,84
Identify Outlier: Look at the data set and try to identify any value that seems significantly different from the rest.By inspection, the number 6 stands out as being much lower than all the other numbers in the data set.
Confirm Outlier: To confirm the outlier, we can calculate the mean and standard deviation of the data set and see if the suspected outlier falls far from the mean compared to the other data points. However, for this problem, since the outlier seems obvious by inspection, we can proceed with identifying 6 as the outlier without further calculations.
