Shirts with a school's mascot were printed, and the table shows the number of people who bought them the first, second, third, and fourth weeks after their release. Which graph can represent the data shown in the table?
Weeks / Number of sales
1 / 22
2 / 50
3 / 62
4 / 75
A bar graph could represent the data shown in the table.
To determine the appropriate graph to represent the given data, we need to analyze the data types and decide which type of graph would be most suitable.
Since the data represents the number of sales of shirts with the school's mascot over different weeks, both the "Weeks" and "Number of sales" are quantitative variables. The "Weeks" variable is discrete, representing a count of the weeks, while the "Number of sales" variable is continuous, representing quantities.
Based on this information, an appropriate graph to represent this data would be a line graph. Line graphs are useful for showing the relationship between two continuous variables over time or some ordered sequence. In this case, the "Number of sales" is the dependent variable that can be graphed on the y-axis, while the "Weeks" can be plotted on the x-axis.
To create the line graph, plot the data points on a coordinate plane with "Weeks" on the x-axis and "Number of sales" on the y-axis. Connect the data points with a line to show the trend in sales over time. The x-axis should be labeled with the weeks (1, 2, 3, 4), and the y-axis should be labeled with the corresponding number of sales (22, 50, 62, 75).
This line graph will visually represent the pattern of shirt sales over the four-week period after their release, allowing for easier analysis and interpretation of the data.
The given data represents the number of sales of shirts with a school's mascot for the first, second, third, and fourth weeks. To represent this data in a graph, we can use a line graph or a bar graph.
A line graph would be suitable for showing the trend or progression of the sales over the weeks. Each week would be plotted on the x-axis (horizontal axis), and the number of sales would be plotted on the y-axis (vertical axis). Points would be plotted for each week's sales, and then connected by a line to show the overall trend.
A bar graph can also be used to represent the data. Each week would be shown as a separate bar on the x-axis, with the height of the bar representing the number of sales for that week.
Both the line graph and the bar graph can effectively represent the given data. The choice between them depends on the specific purpose and preference of the person presenting or analyzing the data.
