Question

which of the following is the best use for a double bar graph? 1 point comparing the test scores of boys and girls in different subjects displaying the temperature change in one city during a week showing the parts of a plant showing the population growth of one city over time study this double bar graph. the average force between the colliding and stationary carts are similar in force but not exactly the same. what is the best reason for this? 1 point average forces during cart collisions 100 80 average force (n) 60 40 0 collision a collision b stationary cart moving cart cart type some variables could not be controlled during the experiment perfectly.

Explanation:

A double - bar graph is used for comparing two sets of data. Comparing test scores of boys and girls in different subjects has two sets of data (boys' scores and girls' scores) for comparison, which is a good fit for a double - bar graph. Displaying temperature change in one city during a week is better with a line graph. Showing parts of a plant is better with a diagram. Showing population growth of one city over time is better with a line graph or a single - bar graph for different time periods. For the second question, in experiments, it's common that some variables cannot be controlled perfectly, which can lead to similar but not identical results.

Answer:

1. Comparing the test scores of boys and girls in different subjects
2. Some variables could not be controlled during the experiment perfectly.
