The horizontal number line on a graph.
- A.
Title
- B.
X - axis
- C.
Y - axis
- D.
Interval
Correct Answer
B. X - axisExplanation
The x-axis is the horizontal number line on a graph. It represents the independent variable or the variable being measured or controlled. It is typically used to plot the values of the independent variable, allowing for easy visualization and analysis of data. The x-axis is labeled with the appropriate units or intervals to represent the range of values being plotted.Rate this question:

The _____ of a set of data is the number or numbers that occur most often.
- A.
Range
- B.
Mean
- C.
Median
- D.
Mode
Correct Answer
D. ModeExplanation
The mode of a set of data refers to the number or numbers that occur most frequently. In other words, it is the value(s) that appear with the highest frequency in the data set. Unlike the mean or median, which focus on the average or middle value, the mode highlights the most common value(s) in the data.Rate this question:

A _____ uses bars to represent the frequency of data that have been organized in intervals.
- A.
Bar graph
- B.
Histogram
- C.
Line plot
- D.
Stem-and-leaf plot
Correct Answer
B. HistogramExplanation
A histogram is a graphical representation of data that uses bars to show the frequency of data within specific intervals. It is commonly used to display the distribution of continuous data. Each bar in a histogram represents a specific interval, and the height of the bar indicates the frequency or count of data points within that interval. Histograms are useful for visualizing the shape, center, and spread of data, making them an effective tool for data analysis and interpretation.Rate this question:

Numbers called _____ can be used to describe the center of data.
- A.
Measures of central tendency
- B.
Data
- C.
Intervals
- D.
Scale
Correct Answer
A. Measures of central tendencyExplanation
Measures of central tendency, such as the mean, median, and mode, are numerical values that represent the center or average of a set of data. They provide information about the typical or central value of the data, allowing us to describe the center of the data distribution. These measures are commonly used in statistics and data analysis to summarize and understand the data set. Therefore, measures of central tendency can be used to describe the center of data.Rate this question:

The vertical number line on a graph.
- A.
Title
- B.
Label
- C.
X-axis
- D.
Y-axis
Correct Answer
D. Y-axisExplanation
The correct answer is y-axis because the y-axis is the vertical number line on a graph. It represents the dependent variable in a graph and is used to measure and plot data points along the vertical axis. The y-axis is typically labeled with the units of measurement and represents the range or values of the dependent variable being studied.Rate this question:

A type of graph that looks like a number line with each piece of data displayed as an x above the number line.
- A.
Line plot
- B.
Scatter plot
- C.
Stem-and-leaf plot
- D.
None of these
Correct Answer
A. Line plotExplanation
A line plot is a type of graph that represents data on a number line, where each data point is shown as an "x" above the number line. This type of graph is useful for displaying the distribution and frequency of data points. It allows for easy comparison and identification of patterns or outliers in the data.Rate this question:

A graphic form using bars that do not touch to make comparisons of statistics.
- A.
Line plot
- B.
Stem-and-leaf plot
- C.
Histogram
- D.
Bar graph
Correct Answer
D. Bar graphExplanation
A bar graph is a graphic form that uses bars that do not touch to represent and compare statistics. Each bar represents a category or variable, and the length of the bar corresponds to the value or frequency of that category. It is an effective way to visually display data and make comparisons between different categories or variables.Rate this question:

A graph that has a column for one place value and ten place value.
- A.
Line plot
- B.
Stem-and-leaf plot
- C.
Scatter plot
- D.
Bar graph
Correct Answer
B. Stem-and-leaf plotExplanation
A stem-and-leaf plot is a graph that displays data by separating each data point into a "stem" (the tens place) and a "leaf" (the ones place). It is used to organize and represent numerical data in a visual manner. In this case, since the graph has a column for both the ones place and the tens place, it suggests that the correct answer is a stem-and-leaf plot.Rate this question:

Groups of numbers - This information goes on the x-axis of a histogram.
- A.
Interval
- B.
Frequency
- C.
Label
- D.
Title
Correct Answer
A. IntervalExplanation
In a histogram, the x-axis represents the groups or intervals of numbers being analyzed. Each interval represents a specific range of values, and the height of the bars on the y-axis represents the frequency or count of data points falling within that interval. Therefore, the correct answer is "interval" because it is the information that is plotted on the x-axis of a histogram.Rate this question:

Another word for average - The sum of the data divided by the number of items in the data set.
- A.
Range
- B.
Mean
- C.
Median
- D.
Mode
Correct Answer
B. MeanExplanation
The given answer, "mean," accurately describes another word for average. The mean of a data set is calculated by finding the sum of all the data points and dividing it by the number of items in the data set. This provides a measure of central tendency that represents the typical value in the data set.Rate this question:

The middle number in a set of data that has been ordered least to greatest.
- A.
Range
- B.
Mean
- C.
Median
- D.
Mode
Correct Answer
C. MedianExplanation
The median is the middle number in a set of data that has been ordered from least to greatest. It represents the value that separates the lower half of the data from the upper half. Unlike the mean, which is the average of all the numbers, the median is not affected by extreme values. It provides a measure of central tendency that is less influenced by outliers, making it a useful statistic for describing the typical value in a dataset.Rate this question:

The difference between the greatest and leaast numbers in a data set.
- A.
Range
- B.
Mean
- C.
Median
- D.
Mode
Correct Answer
A. RangeExplanation
The range is a measure of dispersion that represents the difference between the largest and smallest values in a data set. It provides information about the spread or variability of the data. By calculating the range, one can determine how much the values in the data set vary from each other. Therefore, the range is the correct answer in this case.Rate this question:
-

A table for organizing a set of data that shows the number of pieces of data that fall within given intervals or categories.
- A.
Title
- B.
Range
- C.
Frequency table
- D.
Stem-and-leaf plot
Correct Answer
C. Frequency tableExplanation
A frequency table is a table used to organize a set of data by showing the number of pieces of data that fall within given intervals or categories. It displays the frequency or count of each category or interval in the data set. This table helps to summarize and analyze data, making it easier to identify patterns and trends. It is commonly used in statistics and data analysis to present data in a clear and organized manner.Rate this question:

A piece of data that is quite separated from the rest of the data.
- A.
Outlier
- B.
Mean
- C.
Median
- D.
Mode
Correct Answer
A. OutlierExplanation
An outlier is a piece of data that is significantly different or distant from the rest of the data. It can be an unusually high or low value that does not follow the general pattern of the dataset. Outliers can have a significant impact on statistical analyses and can skew the results, so they are often identified and treated separately.Rate this question:
-
- 15.
Data that are grouped closely together.
- A.
Outlier
- B.
Cluster
- C.
Gap
- D.
Range
Correct Answer
B. ClusterExplanation
Cluster refers to a group of data points that are closely grouped together. In this context, it means that the correct answer is "cluster" because it is the term that best describes data that are grouped closely together.Rate this question:
