AMDM U3 Graphs
| Term | Definition |
|---|---|
| Line Plot | Quick and easy way to organize the data so that the distribution of the data can be easily seen |
| Line plot | Every piece of data is available |
| Line plot | Mean median and mode and range are easily determined |
| Line plot | A working draft that can be easily used to create a pictograph or bar graph |
| Line plot | Not practical for very large data sets |
| Line plot | Not practical for for data with a large number or data values |
| Bar graph | Similar to line plot but more practical for large data sets with few data values |
| Bar graph | Exact data can be reconstructed if data have not been grouped into categories |
| Bar graph | Distribution of data can be easily seen clusters of data gaps in data or bell shaped distribution |
| Bar graph | Range or spread of data is easily determined |
| Bar graph | Mode can be easily seen |
| Bar graph | Mean and median can be determined with some effort |
| Bar graph | Can be used to represent numerical or categorical data |
| Bar graph | Not practical for data with a large number of data values |
| Bar graph | Two coordinates must be read to fully understand the graph |
| Bar graph | Data have to be tallied prior to creating graph |
| Bar graph | Scaling , labeling , and readability need to be considered when creating this graph |
| Stem-and-Leaf Plot | Exact data can be reconstructed |
| Stem-and- Leaf Plot | Easier to see the shape of the data when the number of data values and size of data set are about the same |
| Stem-and-Leaf Plot | Groups data values using their digits |
| Stem-and-Leaf Plot | Distribution of data can easily be seen (i.e., clusters of data, gaps in data, gaps in data, or bell-shaped distribution) |
| Stem-and-Leaf Plot | Range or spread of data is easily determined |
| Stem-and-Leaf Plot | Mean, median, and mode can be calculated |
| Stem-and-Leaf Plot | Back-to-back graphs of this kind can compare two different sets of data |
| Stem-and-Leaf Plot | Not practical for very large data sets since sorting and reorganizing data can be time-consuming |
| Stem-and-Leaf Plot | More restrictive data can histograms are since the size of their classes (groups) is based on their last digits. Histograms are not restricted to any class length |
| Histogram | Convenient for representing large quantities of data |
| Histogram | General distribution of data can be quickly seen |
| Histogram | Similar to stem-and-leaf plots but without the specific data values |
| Histogram | Size of classes is not restricted |
| Histogram | Specific data values are lost-- data cannot be reconstructed |
| Histogram | Appearance of the datas distribution can be manipulated depending on numbers used |
| Histogram | Exact mean median and mode cant be determined |
| Pie chart | Shows the part to whole relationship between data |
| Pie chart | Clusters numerical data into groups |
| Pie chart | Easier to see the fraction of the data satisfying certain conditions |
| Pie chart | Specific data values are lost data cannot be reconstructed |
| Pie chart | Exact mean median mode and range of original numerical data cannot be determined |
| Box & whisker plot | Effective representation for large quantities of data |
| Box & whisker plot | Range con be determined |
| Box & whisker plot | Outliers can be revealed |
| Box & whisker plot | Median and interquartile ranges are easily identified |
| Box & whisker plot | Plots using different sets of data can be easily compared when graphed on the same scale |
| Box & whisker plot | Specific data values are lost data cannot be reconstructed |
| Box & whisker plot | Mean and mode cannot be determined |
| Scatterplot | Shows relationship between two different variables . |
| Scatterplot | If a pattern or trend exist within the relationship , generalizations and/or predictions can be made |
| Scatterplot | Exact data cannot always be determined -- only approximate values will be possible at times |
| Scatterplot | Given there are two values represented at any given point , measures of center are not informative |
| Line graph | Shows the change between two different variables ( where often one variable may be time ) |
| Line graph | Can be misleading due to scale sensitivity |
| Line graph | Only appropriate for displaying two variables with one an independent variable being observed exactly at one consistent intervals |
