Question 11 Mark

Answer the following questions, choosing the correct answer:
Median of a frequency distribution cannot be known from the ogives. (True/ False)

Answer

False.
Explanation:
Graphically Ogives can be determined by the intersection point of the less than Ogive and more than Ogive. The value of x-axis corresponding to the intersection point indicates the median.

Question 101 Mark

Answer the following questions, choosing the correct answer:
Histogram can only be formed with continuous classification of data (True/ False).

Answer

True.
Explanation:
A Histogram can only be formed with the continuous classification of data. The frequency distribution of a continuous series is graphically presented in form of a Histogram. If the given data is not continuous, then it is to be converted into exclusive series before presenting the data in the form of Histogram. Histograms can never be prepared for discrete series.

Question 121 Mark

Answer the following questions, choosing the correct answer:
Histogram and column diagram are the same method of presentation of data (True/ False).

Answer

False.
Explanation:
A histogram and a column/ bar diagram may look similar, but there are certain differences between them such as:

A histogram is a two-dimensional diagram, whereas a column or bar diagram is a one-dimensional diagram.
A histogram has no space between two rectangles, but a bar diagram has equal space between two rectangles.
A histogram is drawn for a continuous variable, whereas a bar diagram is drawn for both discrete and continuous variables.

Thus, a histogram and column diagram are two methods of presenting data.
