To determine if a point is considered an outlier, we can use various methods such as the Tukey's fences or Z-score. In this case, we can examine the data visually by creating a scatter plot.
Given the data points:
x: 1, 2, 3, 4, 5, 6, 7, 8, 9
y: 0.8, 2.1, 3.1, 3.8, 5.2, 8.4, 6.9, 8.1, 9
To create a scatter plot, you can plot the x-coordinate on the x-axis and the corresponding y-coordinate on the y-axis.
Looking at the scatter plot, it's clear that the point (9,9) is not an outlier. Instead, it seems to be aligned with the other data points. Therefore, (9,9) would not be considered an outlier in this case.
To determine outliers with statistical methods like Tukey's fences or Z-score, additional calculations would be needed. Please let me know if you would like further explanation on those methods.
