Bar Graph
This is a graphical means of quantitative comparison by rectangles with lengths proportional to the measure of the data or things compared.
Box And Whisker Plot
This is a visual display of some to the descriptive statistics of a data set. It quickly displays the 5-number summary: the minimum value, the maximum value, the median, the upper quartile, and the lower quartile.
Data
Numbers or facts that describe something. It can be numerical, counted, or descriptive.
Frequency
Often recorded in a table or displayed in a graph, this is the number of times a specific value or observation occurs in a set of data.
Graph
This is the image obtained by plotting all the points that satisfy an equation or inequality. A visual representation of data.
Histogram
A special type of bar graph in which data are grouped into intervals of equal width.
Line Graph
A graph that is represented by points connected by segments.
Mean
This is the sum of all the results included in the sample, divided by the number of observations.
Median
The middle term in a set of data. If the data set has an even number of terms this is the average of the two middle terms.
Mode
This is the most frequently occurring element in a set.
Pictograph
This is a graph that uses pictures to show and compare information. Each symbol represents a given amount.
Range
This is the difference between the maximum and the minimum value in a data set.
Stem And Leaf Plot
A statistical way of displaying elements in a data set. The first digit is on the left side of a vertical line and the rest of the digits lie on the right side of the vertical line.
Table
This is a systematic arrangement of data usually in rows and columns.
Box And Whisker Plot
This is a visual display of some to the descriptive statistics of a data set. It quickly displays the 5-number summary: the minimum value, the maximum value, the median, the upper quartile, and the lower quartile.
Data
Numbers or facts that describe something. It can be numerical, counted, or descriptive.
Double Bar Graph
A graph that allows us to compare two or more pieces of information in one graph.
Frequency (a)
Often recorded in a table or displayed in a graph, this is the number of times a specific value or observation occurs in a set of data.
Frequency (b)
The number of cycles a trigonometric function completes in a given interval.
Frequency Diagram
This is an outline designed to demonstrate or explain the number of times a specified periodic phenomenon occurs within a specified interval.
Frequency Distribution
Values and their frequency displayed in a table or graph.
Frequency Plot
A graph used to characterize the frequency of measurements or summarize the distributions of a variable.
Graph
This is the image obtained by plotting all the points that satisfy an equation or inequality. A visual representation of data.
Histogram
A special type of bar graph in which data are grouped into intervals of equal width.
Interquartile Range
The spread of the middle 50% of the data.
Line Graph
A graph that is represented by points connected by segments.
Mean
This is the sum of all the results included in the sample, divided by the number of observations.
Measures Of Spread
A measurement of the variation of the data. This can include the range, standard deviation, percentiles, quartiles, and interquartile range.
Median
The middle term in a set of data. If the data set has an even number of terms this is the average of the two middle terms.
Mode
This is the most frequently occurring element in a set.
Predict
This is what you do when you use information or data to make an informed guess about what will happen in the future.
Quartile
This is a value in a data set which separates one-fourth of the data from the rest.
Statistics
This is the collection, display, and analysis of data.
Stem And Leaf Plot
A statistical way of displaying elements in a data set. The first digit is on the left side of a vertical line and the rest of the digits lie on the right side of the vertical line.
Tendency
These are statistics that describe the center of a distribution: mean, median, mode. They measure central _____.
Trend
This is the relationship between two sets of data.
