Question 1

Which of the following graphs would indicate a constant relationship between two variables?
A)A bi-modal curve
B)A pictograph
C)A bar graph
D)A straight line graph

Accepted Answer

A straight line graph indicates a constant relationship between two variables, as it shows a consistent rate of change.

Question 2

Which of the following is a process where web charts should NOT be used?
A)Identify students' interest
B)Identify students' background knowledge
C)Organize specific themes or topics
D)Quantify data

Accepted Answer

Web charts, also known as concept maps or mind maps, are primarily used for organizing and visualizing ideas, themes, or concepts in a non-quantitative manner. They are not suitable for quantifying data, which involves numerical measurements and statistical analysis, better represented by bar graphs, line charts, or pie charts.

Question 3

Which of the following is an example of how circle graphs,sometimes called pie graphs should be used?
A)Circle graphs should never be used as a living graph.
B)Circle graphs are useful for showing a part-to-whole relationship.
C)Circle graphs are very good for identifying a median.
D)Circle graphs help understanding increasing relationships.

Accepted Answer

Circle graphs, or pie charts, are best used to show how individual parts make up a whole. They visually represent the proportions of different components within a single entity, making it easy to see the part-to-whole relationships.

Question 4

Graphs formed by lining up children by categories are called ____________________________ graphs.

Accepted Answer

The answer of Graphs formed by lining up children by...

Question 5

Venn diagrams help children sort data according to similarities and differences.

Accepted Answer

Venn diagrams are graphical representations that use circles to show the relationships between different sets of items, specifically highlighting similarities and differences, making them useful tools for sorting data.

Question 6

Charts are useful for organizing data.

Accepted Answer

Charts help in visually organizing and summarizing data, making it easier to understand and interpret patterns, trends, and relationships.

Question 7

____________________ are representations or diagrams that represent a connection or interrelationship among two or more things.

Accepted Answer

The answer of ____________________ are representations or diagrams that represent...

Question 8

Teachers should never use children's opinions for data.

Accepted Answer

Children's opinions can provide valuable insights into their learning experiences, preferences, and understanding, which can be used to inform teaching strategies, curriculum development, and classroom management.

Question 9

Which of the following is a good use of concrete graphs?
A)Concrete graphs must be used when data is constantly changing.
B)Concrete graphs help organize actual materials.
C)Concrete graphs eliminate the need for interpreting data.
D)Concrete graphs are valuable for estimating area.

Accepted Answer

The answer of Which of the following is a good...

Question 10

Which of the following is the statistical term for the term mean?
A)Base line data
B)Average
C)Maximum differential
D)Voided data

Accepted Answer

The term "mean" is synonymous with "average" in statistics, which is calculated by summing all the values in a set and then dividing by the number of values.

Question 11

Which of the following is a characteristic of a histogram?
A)Histograms are a good replacement for a pictograph.
B)Histograms are good for examining range,mean,median,and mode.
C)Histograms are required for organizing a pie chart.
D)Histograms help us develop line graphs.

Accepted Answer

Histograms are particularly useful for analyzing the distribution of data, allowing us to see the range (spread of data), and get a sense of where the mean, median, and mode lie, although they do not directly show these statistics. They display the frequency of data points in contiguous intervals, making them effective for examining the shape of the data distribution.

Question 12

Which of the following is a good reason that young children should be introduced to charting early in their education?
A)It helps make ideas more abstract.
B)Charting causes children to develop consistent behavior patterns.
C)It helps them think of charting as a model and tool.
D)It decreases the need to understand data.

Accepted Answer

Introducing charting early helps children understand it as a model and tool for organizing, analyzing, and presenting information, fostering analytical and critical thinking skills.

Question 13

Which of the following statements support the value of Venn diagrams?
A)Venn diagrams eliminate bad data.
B)Venn diagrams show how some things share common characteristics with other things.
C)Venn diagrams help us understand abstract data.
D)Venn diagrams should be used when numerical inferences are critical.

Accepted Answer

Venn diagrams show how some things share common characteristics with other things.

Question 14

Which of the following best defines the term mode?
A)The mode is the most common value in a list.
B)The mode clarifies how the data was collected.
C)The mode is useful when measurements cannot be made.
D)The mode works best with abstract data.

Accepted Answer

The mode refers to the most frequently occurring value in a dataset, making choice A the correct definition.

Question 15

You can never have more than one mode.

Accepted Answer

A dataset can have more than one mode when two or more values appear with the same highest frequency; such a dataset is referred to as bimodal or multimodal, respectively.

Question 16

A disadvantage with maps is that they cannot be used to examine data.

Accepted Answer

Maps can be used to examine and visualize data, especially geographical or spatial data, allowing for analysis of patterns, distributions, and relationships across different locations.

Question 17

Which of the following defines the range?
A)The range is the spread of data from the most to the least amount.
B)The range identifies the area in the graph.
C)The range should never be over five units.
D)The range indicates the quality of the measurements.

Accepted Answer

The range is a measure of the spread or dispersion of a set of data points, calculated as the difference between the largest and smallest values in the dataset. It gives an idea of how spread out the values are. Choices B, C, and D do not accurately describe the range.

Question 18

Graphs showing decreases in radioactivity always form a graph said to be a ____________________ graph.

Accepted Answer

The answer of Graphs showing decreases in radioactivity always form...

Question 19

When observations cause a person to develop possible explanations,these explanations are called _______________________.

Accepted Answer

The answer of When observations cause a person to develop...

Question 20

When using line graphs,the direction or trends of the line is referred to as the _____________________.

Accepted Answer

The answer of When using line graphs,the direction or trends...
