Data Presentation Flashcards
Main method of conveying information as it is used to explain results and trends, and provide contextual information.
Text presentation
Data are fundamentally presented in
paragraphs or sentences.
Text presentation
Convey information that has been converted into words or numbers in rows and columns.
Table presentation
The most appropriate for presenting individual information, and can present both quantitative and qualitative information.
Table presentation
Useful for summarizing and comparing quantitative information of different variables and information with different units can be presented together.
Table presentation
A table listing all classes and their frequencies
Frequency Distribution
The proportion of the total number of observations that appears in that interval.
Relative Frequency
The percentage of the total number of observations that have a value less than or equal to the upper limit of the interval.
Cumulative Relative Frequency
It is calculated by summing the relative frequencies for the specified interval and all previous one.
Cumulative Relative Frequency
Depicts a frequency distribution for discrete or continuous data.
Histogram
It is a bar graph in which the horizontal scale represents classes and the vertical scale represents frequencies.
Histogram
Simplify complex information by using images and emphasizing data patterns or trends, and are useful for summarizing, explaining, or exploring quantitative data.
Graph presentation
It is constructed by placing a point at the center of each interval such that the height of the point is equal to the frequency or relative frequency associated with that interval.
Frequency Polygons
Points are also placed on the horizontal axis at the midpoints of the intervals immediately preceding and immediately following the intervals that contain observations.
Frequency Polygons
The points are then connected by straight lines.
