When classification is done on the basis of time, the classification is known as temporal classification. Time may be in hours, days, weeks, months, years etc.

Width and number of the bar are immaterial in case of bar diagrams. Bar diagram shows statistical data in terms of length of the bar.

Jatin Singh answered |
Subdivided or component bar diagrams are used when various components of a variable are to be represented. In these diagrams we cannot only present the different values graphically but can also compare parts of one with another.
Statistical data can be presented in- a)one form.
- b)two forms.
- c)three forms.
- d)four forms.

Statistical data can be presented in
a)
one form.
b)
two forms.

three forms.
d)
four forms.

Representation of Data Using Bar Diagrams
Bar diagrams are graphical representations of data using rectangular bars. The bars are drawn horizontally or vertically with equal widths, and the lengths of the bars are proportional to the values they represent. The different types of bar diagrams are simple bar diagrams, multiple bar diagrams, and component bar diagrams.
Simple Bar Diagrams
Simple bar diagrams represent a single variable. They are used to compare the values of a single variable. For instance, if you want to compare the sales of a product across different months, you can use a simple bar diagram. The different months will be represented on the horizontal axis, and the sales figures will be represented on the vertical axis. The bars will have equal widths, and their lengths will be proportional to the sales figures.
Features of Simple Bar Diagrams
• Simple bar diagrams represent a single variable.
• They are used to compare the values of a single variable.
• They have equal-width bars.
• The lengths of the bars are proportional to the values they represent.
• They can be drawn horizontally or vertically.
Conclusion
Simple bar diagrams are effective in representing a single variable. They are easy to understand and can be used to compare different values of a variable. They have equal-width bars, and the lengths of the bars are proportional to the values they represent. Simple bar diagrams can be drawn horizontally or vertically, depending on the nature of the data.

Raman Singh answered |
Sub-divided bar diagrams presented graphically on percentage basis gives percentage bar diagrams. These diagrams are used to highlight the relative importance of the various component parts to the whole.

Understanding Class Intervals
Class intervals are used in statistics to group continuous data into manageable ranges. In this case, we have two intervals: 0-10 and 10-20.
Interpreting the Intervals
- The class interval 0-10 includes all scores greater than or equal to 0 and less than 10.
- The class interval 10-20 includes all scores greater than or equal to 10 and less than 20.
Score of 10 Marks
When a student scores 10 marks, we need to determine which interval they fall into:
- Lower Bound Inclusion: In many statistical contexts, the upper boundary of a class interval is often not included in that interval. Therefore, the score of 10 is considered as the starting point of the next interval.
- Interval Classification: Since the score of 10 marks falls at the boundary between 0-10 and 10-20, it is included in the interval 10-20.
Conclusion
Based on this interpretation, the correct classification for a student scoring 10 marks is:
- Option A: 10-20
This approach ensures clarity in statistical grouping, allowing for accurate data representation and analysis.
