CHAPTER 4: PRESENTATION OF DATA (4.3 Graphical Presentation) Flashcards
Data presentation that portrays numerical figures or relationships among variables in pictorial form
Graphical presentation
A presentation tool that is most suitable to use when we show the results of the study to nonprofessionals
Graph
True or False
A well-desgined graph will always be superior over a statistical table
False
It cannot show all the important details of the data in a graph and does not display the exact figures on the data, but only approximations.
Characteristics of a good chart
Precise enough to allow for the correct interpretation and analysis of the data.
Accurate or Accurate chart
Characteristics of a good chart
A chart that does not confuse the reader when it comes to the interpretation of the results
Clear or Clear chart
Characteristics of a good chart
A chart that does not distract the attention of the reader from the message that we wish to communicate
Simple or Simple chart
Chart useful for presenting historical data and is effective in showing the movement of a series over time
Line chart
Types of line charts
Type of chart that only has one curve and is appropriate for one series of time data
Simple Line Chart
Types of line charts
Type of chart that shows two or more curves. We use this if we wish to compare the trends in two or more data series
Multiple Line Chart
Chart that is used to compare amounts in a time series data. Focuses on the differences in magnitude rather than the movement of a series
Column Chart
Types of Column Charts
Used when there is only one time series data. Used to show the increase or decrease in amount or number of the variable of interest
Simple Column Chart
Types of Column Charts
Used when there are two or more time series data for comparison purposes
Grouped Column Chart
Figure 4.2, pg. 150
Types of Column Charts
Used to show the component parts of a series of values
Subdivided Column Chart
Figure 4.2, pg. 150
Types of Column Charts
Similar to the subdivided column chart but the components are in percentages
100% Subdivided Column Chart
Figure 4.2, pg. 150
Types of Column Charts
This chart is best for showing increases and decreases, gains and losses, and positive and negative numbers over time
Net Deviation Column Chart
Figure 4.2, pg. 150
Types of Column Charts
Similar to simple column chart but there are no spaces in between the columns to save space. More appropriate if the series is long because it avoids narrow columns and too small gaps in between columns.
Connected Column Chart
Figure 4.2, pg. 150
Chart that is appropriate when we wish to show the distribution of categorical data, it is arranged horizontally.
Horizontal Bar Chart
Types of Horizontal Bar Charts
Useful when comparing the magnitudes of the different categories of a variable of interest
Simple Bar Chart
Figure 4.15., pg. 154
Types of Horizontal Bar Charts
Used for making comparisons between two or more sets of data, all sorted using the same set of categories
Grouped Bar Chart
Figure 4.15., pg. 154
Types of Horizontal Bar Charts
Similar to the grouped bar chart but instead of having several barrs for the various categories, we divide one bar into several components. Uses absolute numbers in the scale values
Subdivided Bar Chart
Figure 4.15., pg. 154
Types of Horizontal Bar Charts
Uses percentages in the scale values, we divide each bar into segments and the segments total to 100%
Subdivided 100% Bar Chart
Figure 4.15., pg. 154
A chart shaped like a circle that is divided into several sections. Each section indicates the proportion of each component or category.
Pie Chart
Useful for data sorted into categories for a specific period
A chart that is like a horizontal bar chart but instead of using bars, we use symbols or pictures to represent the magnitude. Its purpose is to get the attention of the reader
Pictograph
This chart shows statistical data in geographical areas
Statistical Maps
Types of Statistical Maps
This type of map makes use of shading patterns that indicates the degree of magnitude
Shaded Map
Types of Statistical Maps
This type of chart gives either the location or the number of establishments in a certain geographic area.
Dot Map see this for example
