Q. Select the outlier in the data set.9,52,54,57,58,59,65,67,77
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 set. Data set: 9,52,54,57,58,59,65,67,77
Find outlier number: Look for the number that seems significantly different from the rest of the numbers in the data set.By inspection, we can see that the number 9 is much lower than all the other numbers, which are all above 50.
Determine if outlier: Determine if 9 is an outlier by comparing it to the rest of the data set. The rest of the numbers are clustered between 52 and 77, while 9 is much lower than the smallest number in that cluster (52). This suggests that 9 is an outlier.
