This pie chart intends to show the proportion of students in third grade. Is it true or false?
-
True
-
False
Correct Answer
A. FalseExplanation
The given answer is false because the pie chart does not show the proportion of students in third grade. The question does not provide any information about what the pie chart actually represents, so it is not possible to determine its accuracy.Rate this question:

From this table of personnel data, you want to draw a chart. Which chart creates a perceptually misleading comparison?
-
Graph 1
-
Graph 2
Correct Answer
A. Graph 2Explanation
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:

The larger the scale of y-axis is, the _________ the differences between 2 lines/columns is.
-
Smaller
-
Larger
Correct Answer
A. SmallerExplanation
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.Rate this question:

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?
-
Graph 1
-
Graph 2
Correct Answer
A. Graph 2Explanation
Without the graphs being provided, it is impossible to determine which one is more likely to be an accurate picture of the data.Rate this question:

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?
-
6.0-8.0
-
6.5-8.0
-
6.0-7.5
-
6.9-7.1
Correct Answer
A. 6.0-8.0Explanation
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.Rate this question:

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?
-
5-14
-
7-14
-
0-14
-
10-14
Correct Answer
A. 0-14Explanation
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.Rate this question:

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?
-
The right chart
-
The left chart
Correct Answer
A. The right chartExplanation
