What kind of graph would you use to show the number of twins born each year?
I think a line graph
Would you use a line plot or bar graph to display a survey of what teens do for entertainment after school?
I think line plot
I would use a bar graph for both.
For the number of twins born each year, a line graph would indeed be a suitable choice. A line graph is commonly used to display data over a period of time or to show the relationship between two variables. In this case, the x-axis would represent the years, and the y-axis would represent the number of twins born. Each year's data point would be plotted on the graph, and a line would connect these points, allowing you to see the trend over time.
Regarding the survey of what teens do for entertainment after school, a line plot would not be the most appropriate graph. A line plot, also known as a dot plot, is used to display the frequency of a specific data point or category. It is typically used when the data set is small and discrete. However, a survey of what teens do for entertainment after school would likely involve multiple categories and larger data set. In this case, a bar graph would be more suitable. A bar graph allows you to compare different categories or groups by using rectangular bars of different lengths to represent the data. Each category of entertainment (e.g., sports, arts, video games) would have its bar, and their heights would represent the frequency or percentage of teens engaging in each activity.
