Question

recognizing the impact of outliers
which statement is true?
there is no relationship between the height of the
plant and its age.
although the outlier is an extreme value, it should
be included in the interpretation.
by excluding the outlier, a better description can be
given for the data set.

Explanation:

• First, analyze the relationship between height and age. From the scatter - plot, we can see that as the age (weeks) increases, the height (inches) generally has an increasing trend, so the statement “There is no relationship between the height of the plant and its age” is false.
• Outliers are extreme values. In data analysis, when an outlier is clearly a measurement error or an unusual case that does not represent the general pattern of the data, excluding it can help us better describe the relationship between the two variables (age and height in this case). If we include the outlier, it may distort the overall trend of the data.

Answer:

By excluding the outlier, a better description can be given for the data set.
