Scatter Plots Trends and Outliers

What is the concept of an outlier in a scatter plot?

• A data point that is significantly different from other data points in the plot

• A data point that is exactly in the middle of the plot

• A data point that is the average of all other data points in the plot

• A data point that is irrelevant to the overall trend of the plot

Explain why outliers are important to consider when analyzing data in a scatter plot.

• Outliers only occur due to errors in data collection and are not relevant to the analysis

• Outliers have no impact on the overall trend and correlation in a scatter plot

• Outliers can significantly affect the overall trend and correlation in a scatter plot, so it's important to consider them when analyzing data.

• Outliers should be ignored completely when analyzing data in a scatter plot

Identify the outlier in the following scatter plot: most of the points are clustered around (5, 10) but there is one point at (20, 10).

• (20, 10)

• (15, 10)

• (10, 5)

• (5, 10)

How can outliers affect the trend line in a scatter plot?

• Outliers have no impact on the trend line

• Outliers make the trend line more accurate

• Outliers can significantly affect the trend line

• Outliers only affect the scatter plot, not the trend line

In this image, how would you describe the point that does not fit the pattern of the other dots?

• The point is a linear model.

• The point is an outlier.

• The point is the range.

• The point is the median.
