Full solution
Q. Select the outlier in the data set.
- 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:
- Spot outlier: Look at the data set and try to spot any value that seems significantly different from the others.By inspection, the number stands out as being much lower than all the other values 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, in this case, since the number is so much lower than the rest of the numbers, which are all or higher, we can reasonably conclude that is the outlier without further calculations.
