MCQs about Statistical Charts and Graphs
The graphical & charting representations are common methods to get visual inspection about data. The graphs are the graphical summaries of the data. Graphs represent diagrams of a mathematical or statistical function, while a chart is a graphical representation of the data. In the charts, the data is represented by symbols.
The most commonly used graphical summaries of the data are bar charts, histograms, pie charts, line graphs. Graphs are used to get quick ideas and decisions about phenomena under study. Generally, graphs and charts are used to get the distribution of data. However, different graphs and charts are used to get quite different information.
For example, line graphs are used to get ideas about changes over short/long periods of time. Bar graphs and their further types (cluster bar graph, stacked bar graph) are used to compare the differences among the groups. Pie charts are used to get the proportional contribution of each group in relation to as a whole.
The important features of graphs and charts are (1) Title: the title of charts and graphs tells us what the subject of the chart or graph is, (2) Vertical Axis: the vertical axis tells us what is being measured in the chart and a graph, and (3) Horizontal Axis: the horizontal axis tells us the units of measurement represented.
There is various mathematical and statistical software that can be used to draw charts or graphs. For example, MS-Excel, Minitab, SPSS, SAS, STATA, Graph Maker, Matlab, Mathematica, R, Exlstat, Python, and Maple, etc.
