Question

HELP ME PLEASE ITS DUE TODAY!!! The following data shows the number of times a class of 7th graders ate breakfast over a 30-day period.

{4, 18, 22, 25, 15, 12, 22, 14, 19, 30, 24, 20, 21, 24, 29, 16, 20, 27, 24, 25}

Part A: Determine the best graphical representation to display the data. Explain why the type of graph you chose is an appropriate display for the data. (2 points)

Part B: Explain, in words, how to create the graphical display you chose in Part A. Be sure to include a title, axis label(s), scale for axis if needed, and a clear process of how to graph the data. (2 points)

Answer 1

A bar graph is the best graphical representation for displaying the number of times a class of 7th graders ate breakfast over a 30-day period. To create the graph, label the vertical axis with the frequency of breakfasts eaten, label the horizontal axis with the class of 7th graders, and draw bars to represent the number of times each class ate breakfast.

Step-by-step explanation:

Part A: The best graphical representation to display the data would be a bar graph. A bar graph is appropriate for displaying this data because it allows us to compare the number of times each class of 7th graders ate breakfast over the 30-day period. The height of each bar represents the frequency of breakfasts eaten, making it easy to see the variation in the data.

Part B: To create the bar graph, you would start by labeling the vertical axis with the frequency of breakfasts eaten (you can choose intervals according to the range of the data). On the horizontal axis, you would label each class of 7th graders. Then, for each class, you would draw a bar whose height corresponds to the number of times that class ate breakfast.
