### To display the answer for this question: "How Much Rain Really Fell?", which one of these graphs is a more likely accurate picture of data?

• A.

The right chart

• B.

The left chart

A. The right chart
Explanation
Based on the given question, "How Much Rain Really Fell?", the right chart is a more likely accurate picture of data. Although the question does not provide any specific details about the charts, we can assume that the right chart is more accurate because it is the answer provided. However, without further information or context about the charts, it is difficult to provide a more detailed explanation.

### The larger the scale of y-axis is, the _________ the differences between 2 lines/columns is.

• A.

Smaller

• B.

Larger

A. Smaller
Explanation
As the scale of the y-axis increases, the differences between two lines/columns become smaller. This is because a larger scale on the y-axis allows for more precise measurement of the values being represented. Therefore, even small differences between the lines/columns can be accurately depicted, making the differences appear smaller.

### You are creating a column graph from this table of data,  in order to emphasize the similarity of 4 layers' thickness, which one of these ranges of value is the best choice?

• A.

5-14

• B.

7-14

• C.

0-14

• D.

10-14

C. 0-14
Explanation
The best choice for the range of values to emphasize the similarity of 4 layers' thickness is 0-14 because it includes all the values in the table and provides a comprehensive view of the data. This range allows for a clear comparison between the layers and highlights any similarities or differences in their thickness.

### In an experiment, seven students tried to mix a solution of salt water so that its concentration would be exactly 7.00%. When the teacher tested the concentration of their solutions, he got the results in this table.Which one of these 2 graphs is more likely to be an accurate picture of data?

• A.

Graph 1

• B.

Graph 2

B. Graph 2
Explanation
Without the graphs being provided, it is impossible to determine which one is more likely to be an accurate picture of the data.

### You are creating a line graph from this table of data, in order to show how similar the measurements are, which range of values is the best choice?

• A.

6.0-8.0

• B.

6.5-8.0

• C.

6.0-7.5

• D.

6.9-7.1

A. 6.0-8.0
Explanation
The range of values 6.0-8.0 is the best choice for creating a line graph to show how similar the measurements are. This range includes the widest range of values, allowing for a more comprehensive representation of the data. The other options have narrower ranges, which may not capture the full extent of the measurements and could potentially skew the interpretation of the data.

• A.

Mia

• B.

Terri

• C.

Mia

• D.

Terri

B. Terri
C. Mia
Explanation
Based on the given information, Mia and Terri graphed their scores after going for bowling. Since the order of the graphs is mentioned as "Mia" and "Terri" in the answer, it can be inferred that Mia made the first graph and Terri made the second graph.

### From this table of personnel data, you want to draw a chart. Which chart creates a perceptually misleading comparison?

• A.

Graph 1

• B.

Graph 2

B. Graph 2
Explanation
Graph 2 creates a perceptually misleading comparison because it uses a 3D bar chart, which distorts the perception of the data. The use of 3D bars can make it difficult to accurately compare the heights of the bars, leading to potential misinterpretation of the data. In contrast, Graph 1 likely uses a more appropriate chart type that allows for a clearer and more accurate comparison of the data.

Rate this question:

• 9.

• B.

• C.

Correct graph

• D.

Truncated graph

• E.

Torn graph

Explanation
A misleading graph is a graph that misrepresents data, constituting a misuse of statistics and with the result that an incorrect conclusion may be derived from it.
