Q. Select the outlier in the data set.1,76,82,84,85,87,88,90,97
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. In this case, we are looking at the data set: 1,76,82,84,85,87,88,90,97. We need to determine which number stands out as being significantly different from the others.
Look for outlier: Look for the number that is significantly lower or higher than the rest of the numbers in the data set. By inspecting the data set, we can see that the number 1 is much lower than all the other numbers, which are all above 75. This suggests that 1 is the outlier.
Confirm suspected outlier: Confirm that the suspected outlier is indeed significantly different from the rest of the data.To confirm that 1 is an outlier, we can compare it to the rest of the numbers and see that there is a large gap between 1 and 76, the next closest number in the set. This confirms that 1 is the outlier.
