A scatter chart would be the best choice for presenting data on the relationship between two continuous variables, such as the price and energy cost of refrigerators. It would allow for the visualization of any patterns or trends in the data, and for the identification of any potential outliers. A pie chart would not be appropriate for this type of data, as it is designed for categorical data. A side-by-side bar chart would be more appropriate for comparing data across different categories, rather than across continuous variables. A contingency table would not be appropriate for this type of data, as it is designed for summarizing categorical data in terms of the frequency or proportion of observations in each combination of categories.
