In a scatter plot, what does it mean if the points are mostly clustered around a line?

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
