The much higher poing is an outlier and it makes the result skewed
How would the much higher poing affect the result?
From the question, we have the following parameters that can be used in our computation:
The graph
When most of students' points in a graph are on a line, it shows a correlation among their data.
However, the presence of a single point that is much higher from this line shows there is an outlier in the data values
Outliers can heavily impact the interpretation of results and they may skew the calculated line of best fit or the histogram of the data values
