| Answers Explanation & Hints:
Since the objective is to display the outliers of a data set, the best chart used to display this visually would be a scatter plot.
The main types of charts used to display data visually are:
- Pie charts are used to show the composition of a static number. Segments represent a percentage of that number. The total sum of the segments must equal 100%.
- Line charts are one of the most commonly used types of comparison charts. Use line charts when you have a continuous set of data, the number of data points is high, and you would like to show a trend in the data over time.
- Column charts are positioned vertically. They are probably the most common chart type used when you want to display the value of a specific data point and compare that value across similar categories.
- Bar charts are similar to column charts except they are positioned horizontally. Longer bars indicate larger numbers. They are best used when the names for each data point is long.
- Scatter plots are very popular for correlation visualizations, or when you want to show the distribution of a large number of data points. Scatter plots are also useful for demonstrating clustering or identifying outliers in the data.
