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 year).

• A bar chart is for comparing categories, not showing change over time.
• A pie chart is for showing proportions of a whole, not time - related change.
• A dot plot is for showing the distribution of a single variable, not time - series data.
• A line graph is ideal for displaying data points over a continuous interval (like time) to show trends or changes, which matches the need to show pond depth change over a year.

Answer:

D. A line graph
