Question

question: a group of scientists measures the depth of a pond daily for one year. which type of chart or graph are the scientists most likely to use to show how the depth of the pond changes over the course of the year? answer options: select one of four a bar chart a pie chart a dot plot a line graph

Explanation:

To determine the appropriate chart, we analyze the purpose: showing how pond depth changes over time.

• A bar chart is for comparing categories, not showing change over time.
• A pie chart shows proportions of a whole, not time - related change.
• A dot plot is for displaying the distribution of data points, not for showing change over time.
• A line graph is ideal for showing trends or changes over a continuous variable (like time, here daily over a year). So the scientists would use a line graph.

Answer:

D. A line graph
