Is there an outlier in the data? if so what is it? explain how you know.
To determine if there is an outlier in the data, we can calculate the interquartile range (IQR) and then use the 1.5*IQR rule to identify any values that fall outside of this range.
If a value is less than Q1 - 1.5*IQR or greater than Q3 + 1.5*IQR, then it is considered an outlier.
Additionally, we can also visually inspect the data using a box plot to see if there are any values that are significantly different from the rest of the data points.
Without knowing the specific data set you are referring to, it is difficult to identify the outlier. But using the methods mentioned above, you can determine if there is an outlier present in the data.
