Histogram Flashcards
Main method of conveying information as it is used to explain and trends, and provide contextual.
Text presentation
Data are fundamentally presented in paragraphs or sentences.
Text presentation
Clear and effective way of conveying data and trends, especially when you want to provide context or explain results.
Text presentation
Convey information that has been converted into or 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
A table listing all classes and their frequencies.
Frequency distribution
For nominal and ordinal data, a frequency distribution consists of a set of classes or categories along with the numerical counts that correspond to each one.
Frequency distribution
Organizes data points into categories or intervals and shows how frequently each category occurs.
Frequency distribution
It provides a clearer picture of how data is spread across different values or ranges.
Frequency distribution
The proportion of the total number of observations that appears in that interval.
Relative Frequency
It s computed by dividing the number of values within an interval by the total number of values in the table, multiplied by 100% to obtain the percentage of values in the 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 Frequency
It is calculated by summing the relative frequencies for the specified interval and all previous ones.
Cumulative Frequency
Simplify complex information by using images and emphasizing data patterns or trends, and are useful for summarizing, explaining, or exploring quantitative data.
Graphs
Popular type of graph used to display a frequency distribution for nominal or ordinal data.
Bar Chart
In a bar chart, the various categories into which observations fall are presented along with what axis?
Horizontal axis
A bar that is drawn above each category such that the height of the bar represents either the frequency or the relative frequency of observations within that class.
Vertical bar
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
It is used to represent a frequency distribution for a categorical variable, and the frequencies are displayed by the heights off vertical bars, which are arranged in order from highest to lowest.
Pareto Chart
What chart can use when the variable displayed on the horizontal axis is qualitative or categorical?
Pareto Chart
Useful for comparing individual categories with the total.
Pie Chart
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
Another type of graph that can be used to summarize a set of discrete or continuous observations.
Scatter Plots (one-way)
Used a single horizontal axis to display the relative position of each data point in the group.
Scatter Plots (one-way)
Used to depict the relationship between two different continuous measurements.
Scatter Plots (two-way)
Each point on the graph represents a pair of values.
Scatter Plots (two-way)
The scale for one quantity is marked on the horizontal axis, or x-axis, and the scale for the other on the vertical axis, or y-axis.
Scatter Plots (two-way)
