# MCQs Charts and Graphs 1

These MCQs Charts and Graphs contain questions from different topics related to graphical Presentation of data in statistics MCQs which include, Histogram, Frequency distribution (Relative frequency distribution, Cumulative Frequency distribution),  Bar chart, Pie chart, Line graph, scatter diagram, etc.

1. In constructing a histogram, if the class interval size of one class is double than others, then the width of that bar should be

2. The graph of cumulative frequency is called

3. Total angles in Pie chart are

4. Dividing the upper and lower limits of a particular class we get

5. Total Relative Frequency is always

6. Cumulative Frequency Curve is also called

7. The budgets of two famalies can be compared by _____________.

8. While constructing Frequency Distribution, the number of classes used depends upon

9. The graph of the normal distribution depends on

10. A Histogram is a set of adjacent

11. Graph of time series data is called

12. An ogive is a

13. The graph of a frequency distribution is called

14. Cumulative Frequency is ___________________ frequency

16. The average value of the lower and upper limit of a class is called

17. The process of systematic arrangement of data in rows and columns is called

18. _______________________ use the division of a circle into different sectors

19. The graph showing the paired points ($X_i, Y_i$) is called a

Graphs and charts are common methods to get a visual inspection of data. Graphs and charts 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 graphs and charts 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 and graphs. For example, MS-Excel, Minitab, SPSS, SAS, STATA, Graph Maker, Matlab, Mathematica, R, Exlstat, Python, and Maple, etc. Currently working as Assistant Professor of Statistics in Ghazi University, Dera Ghazi Khan. Completed my Ph.D. in Statistics from the Department of Statistics, Bahauddin Zakariya University, Multan, Pakistan. l like Applied Statistics, Mathematics, and Statistical Computing. Statistical and Mathematical software used is SAS, STATA, GRETL, EVIEWS, R, SPSS, VBA in MS-Excel. Like to use type-setting LaTeX for composing Articles, thesis, etc.
