Graphics Interpretation - Bar Graph Iterations

The bar graph shows the results of a drug study with four groups of participants. In the graph, each bar represents the number of participants who reported each of three symptoms: fatigue, irritability, and headaches.

From each drop-down menu, select the option that creates the most accurate statement based on the information provided.

Participants in [[dropdown1]] reported the greatest number of cases of fatigue.

Between all four groups, a total of [[dropdown2]] participants reported irritability.

Incorrect.

Group D had the second-greatest number of cases of fatigue, not the greatest number.

From the key, fatigue is represented by the blue bars. Find the group that has the tallest blue bar.

That's right!

From the key, fatigue is represented by the blue bars. From the graph, the number of cases of fatigue were as follows:

• Group A: 31

• Group B: 27

• Group C: 41

• Group D: 31

Since Group C has the tallest bar, the answer is Group C.

Incorrect.

Group B had 27 cases of fatigue, which is the least number of cases of fatigue. You need to find the group with the greatest number of cases of fatigue.

From the key, fatigue is represented by the blue bars. Find the group that has the tallest blue bar.

Incorrect.

Although fatigue was the most-reported symptom in Group A, Group A did not have the greatest number of cases of fatigue out of the four groups.

From the key, fatigue is represented by the blue bars. Find the group that has the tallest blue bar.

Yes!

From the key, irritability is represented by the red bars. Find the number of participants who reported irritability in each group:

• Group A: 29

• Group B: 13

• Group C: 38

• Group D: 22

Then add up these numbers.

$$29+13+38+22=102$$

Incorrect.

You may have gotten this value if you found the total number of participants who reported fatigue, instead of irritability.

Find the number of participants who reported irritability in each group and then add up these numbers.

Incorrect.

You may have gotten this value if you found the total number of participants who reported headaches, instead of irritability.

Find the number of participants who reported irritability in each group and then add up these numbers.
