An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (1)
The data represents plant mass over 4 weeks.
A line graph is best for showing trends over time.
Bar graphs can compare values, but line graphs emphasize change.
Therefore, a line graph is the most appropriate way to present the data.
Explanation
Understanding the Data We are given a table of data showing the plant mass (in grams) measured over 4 weeks. Our goal is to determine the most appropriate type of graph to represent this data from the given options: bar graph, chart, line graph, and pie graph.
Analyzing Graph Options Let's consider each option:
Bar graph: A bar graph would represent the plant mass for each week as a separate bar. This is useful for comparing the mass at different weeks.
Chart: This is a general term and not specific enough.
Line graph: A line graph would connect the data points with a line, showing the trend of plant mass over time. This is useful for visualizing the growth of the plant.
Pie graph: A pie graph would show the proportion of the total mass at each week. This is not appropriate because it doesn't effectively show the change in mass over time.
Choosing the Best Representation Since the data represents the growth of the plant over time, a line graph is the most suitable option to visualize the trend. A bar graph could also work, but a line graph emphasizes the change over time more clearly.
Final Answer Therefore, the most appropriate way to present the data is a line graph.
Examples
Imagine you are tracking the sales of a product each month. A line graph would help you visualize whether sales are increasing, decreasing, or staying constant over time. Similarly, in scientific experiments, line graphs are used to show how a variable changes in response to another variable, such as the effect of temperature on reaction rate. Understanding how to choose the right type of graph helps in effectively communicating data and identifying trends.
