Test: Statistical Description Of Data - 3

​For the class 20-30, cumulative frequency is

 Difference between the maximum and minimum value of a given data is called

 The best method of presentation of data is 

A pie diagram is used to represent the following data: 

The central angles in the pie diagram corresponding to income tax and wealth tax respectively:

The following data relates to the marks of a group of  students.
Marks                         No. of Students 
More than 70%                          07
More than 60%                          18
More than 50%                          40 
More than 40%                          60 
More than 30%                          75 
More than 20%                         100 
How many students have got marks less than 50%?

If calss interval is 10-14, 15-19, 20-24, then the first class is 

 Which of the following is not a two dimensional diagram?

 The difference between the upper and lower limit of a class is called ___________.

To draw Histogram, the frequency distribution should be:

Cost of Sugar in a month under the heads raw materials, labour, direct production and others were 12, 20, 35 & 23 units respectively. The difference between their central angles for the largest & smallest components of the cost of Sugar is

What is a exclusive series?

The breadth of the rectangle is equal to the length of the class interval in

The frequency of class 20-30 in the following data 

Frequency Density can be termed as:

 The Graphical representation by which median is calculated is called 

Arrange the following dimension wise : pie-diagram, bar-diagram and cubic diagram.

For the overlapping classes 0-10, 10-20, 20-30 etc. The class mark of the class 0-10 is

 In Histogram, the classes are taken

 The curve obtained by joining the points, whose x-coordinates are the upper limits of the class-intervals and y coordinates are corresponding cumulative frequencies is called

For non-overlapping classes 0-19, 20-39, 40-59 the class mark of the class 0-19 is

The Chronological classification of data are classified on the basis of: 

An ogive can be prepared in ____________different ways.

Diagrammatic representation of the cumulative frequency distribution is

For overlapping class-intervals the class limit & class boundary are

Classification is of

Upper boundary of any class coincides with the lower boundary of the next class. 

For obtaining frequency polygon we join the successive points whose abscissa represent the corresponding class frequency________

Excepting the first and the last, all other class boundaries lie midway between the upper limit of a class and the lower limit of the next higher class. 

Difference between the maximum & minimum value of a given data is called 

When one end of a class is not specified, the class is called 

 The lower extreme point of a class of called 

When the width of all classes is same, frequency polygon has not the same area as the Histogram.

To find the mode graphically 

 When all classes have equal width, the heights of the rectangles in Histogram will be numerically equal to the

Histogram emphasizes the widths of rectangles between the class boundaries. 

The difference between the upper boundary and the lower boundary of a class is called

Which of the following can be determined by using the Ogive curve?
