Question

Anjuli performed an experiment to determine the respiration rate of yeast. She determined this by measuring the

amount of carbon dioxide (CO2) that was produced. Then, she created the following graph.
Her teacher suggested that she redraw her graph as a line graph. Why should she redraw the graph?
• A line graph looks better in a scientific report.
• She was measuring a rate of change.
• She had graphed the wrong relationship.
• Her experiment had many different variables.

Answer 1

The correct answer is B. She was measuring a rate of change.

Step-by-step explanation

A linear graph is a type of graph that contains a series of data represented by points joined by linear segments, which allow you to quickly check the change in the trend of the data. Therefore, inline graphs quantitative variables are usually used to see their behavior over time. According to the above, Anjuli had to use a linear graph to express the information in the graph more clearly, because the data that he was using in his graph were quantitative variables. Also, she wanted to express the respiration rate of the yeast per minute. According to the above, the correct answer is B. Ella She was measuring a rate of change.
