To represent the given data, which includes years and corresponding prices, the most appropriate method would be a scatterplot.
A scatterplot is useful for visualizing the relationship between two numerical variables—in this case, the year (as the independent variable) and the price (as the dependent variable). This format allows you to see trends, such as whether the price is increasing over the years.
The other options, such as a two-way frequency table, pie chart, or frequency table, are not suitable for this type of data where we are interested in the relationship between continuous variables over time.
