Presentation and display of quantitative data Flashcards
What is a graph in quantitative data presentation
A visual representation of data used to show trends patterns or relationships
What is a table in quantitative data presentation
A systematic arrangement of data into rows and columns for clear presentation
What is a scattergram in quantitative data presentation
A graph used to display the relationship between two co-variables in a correlational analysis
How are data points plotted on a scattergram
Each point represents one pair of scores on the two co-variables
What does a scattergram show
The strength and direction of the relationship between co-variables
What type of data is required for a scattergram
Data for two co-variables which are continuous
What is a bar chart in quantitative data presentation
A graph used to display data from discrete categories with bars separated by gaps
What type of data is used in a bar chart
Categorical data or data in discrete categories
How are bars presented in a bar chart
Bars are separated by spaces to show the data are discrete
What is a histogram in quantitative data presentation
A graph used to display frequency data from continuous data
What type of data is used in a histogram
Continuous data divided into intervals
How are bars presented in a histogram
Bars touch each other to show data are continuous
What does the height of a bar show in a histogram
The frequency of scores within that interval
What is a key difference between bar charts and histograms
Bar charts show discrete data with gaps between bars histograms show continuous data with no gaps
In a table how should data be clearly presented
Each row and column should have clear labels and units if applicable
When would a psychologist use a bar chart
When data are in categories or conditions and are discrete
When would a psychologist use a scattergram
When looking for a relationship between two continuous co-variables
When would a psychologist use a histogram
When displaying frequency data for continuous variables
