A dot plot is best applied when A) a single variable is summarized.
In statistics, a dot plot is a simple data visualization tool used to summarize and display the distribution of a single quantitative variable. It involves placing a dot or symbol above a number line for each data point in the dataset. By stacking the dots vertically for repeated values, a visual representation of the frequency or distribution of the variable can be observed.
Dot plots are particularly useful when summarizing a single variable because they provide a clear picture of the data’s distribution, allowing one to easily identify patterns and outliers. They are especially effective for small to moderate-sized datasets where the individual data points can be visually represented without becoming overwhelming.
On the other hand, when the mean, median, and mode are equal, it indicates a symmetrical distribution which can be explored through other graphical representations such as histograms or box plots. In terms of summarizing the relationship between two variables, alternative visualizations like scatter plots or line graphs are more suitable for capturing the dependencies and patterns between the variables.
