MATHS M.C.Q

In a histogram the class intervals or the group are taken along:

1. Y-axis.
2. X-axis.
3. Both of X-axis and Y-axis.
4. In between X and Y axis.

A frequency polygon is constructed by plotting frequency of the class interval and the:

1. Upper limit of the class.
2. Lower limit of the class.
3. Mid value of the class.
4. Any values of the class.

In the 'less than' type of ogive the cumulative frequency is plotted against:

1. The lower limit of the concerned class interval.
2. The upper limit of the concerned class interval.
3. The mid-value of the concerned class interval.
4. Any value of the concerned class interval.

A histogram is a pictorial representation of the grouped data in which class intervals and frequency are respectively taken along:

1. Vertical axis and horizontal axis.
2. Vertical axis only.
3. Horizontal axis only.
4. Horizontal axis and vertical axis.

Which one of the following is not the graphical representation of statistical data:

1. Bar graph.
2. Histogram.
3. Frequency polygon.
4. Cumulative frequency distribution.

In a histogram the area of each rectangle is proportional to:

1. The class mark of the corresponding class interval.
2. The class size of the corresponding class interval.
3. Frequency of the corresponding class interval.
4. Cumulative frequency of the corresponding class interval.

In a histogram, each class rectangle is constructed with base as:

1. Frequency.
2. Class-intervals.
3. Range.
4. Size of the class.

In a frequency distribution, ogives are graphical representation of:

1. Frequency.
2. Relative frequency.
3. Cumulative frequency.
4. Raw data.
