Choose two of the following types of displays: dot plots, stem and leaf plots, histographs, pictographs, line plots, or circle graphs. In which situations is it appropriate to display data using each type you selected?

To determine the appropriate situations to display data using different types of displays, let's consider the characteristics of each:
1. Dot plots: Dot plots are suitable for displaying quantitative data when you have a relatively small dataset. They are good for showing the distribution and density of data points, especially when you have distinct values in your dataset.
2. Stem and leaf plots: Stem and leaf plots are useful for displaying numerical data, especially when you want to retain the original values. They provide a simple way to organize and visualize data while showing the distribution and individual values.
3. Histograms: Histograms are ideal for representing the distribution of continuous numerical data. They use bars to show the frequency or count of observations within different intervals or bins of data. Histograms are particularly useful for visualizing the shape, central tendency, and spread of data.
4. Pictographs: Pictographs use pictures or icons to represent numerical data. They are most appropriate when visualizing categorical or discrete data, especially for presenting information to a broader audience, including children or individuals with limited statistical knowledge.
5. Line plots: Line plots are beneficial for displaying trends or changes over time. They represent data points as dots connected by lines, making them useful for illustrating continuous or categorical data collected over successive time intervals.
6. Circle graphs: Circle graphs, also known as pie charts, are suitable for displaying parts of a whole or proportions. They are effective when you want to represent the composition or relative sizes of different categories or groups.
Based on these characteristics, here are two types of displays and their appropriate situations:
1. Dot plots and stem and leaf plots: These types of displays are suitable for displaying numerical data with a relatively small or discrete dataset. They are especially useful when you want to show the individual values and their distribution.
2. Histograms and circle graphs: Histograms are ideal for visualizing the distribution and frequency of continuous numerical data, while circle graphs are useful for representing proportions or parts of a whole.
Remember, the selection of a specific display type depends on the nature of the data and the message you want to convey. It's always important to consider the characteristics of each display and choose the one that best represents the data accurately and effectively.
