  • Question 1
    1 / -0

    If vertical lines are drawn at every point of straight line in frequency polygon then by this way frequency polygon is transformed into

    Solution

    histogram

  • Question 2
    1 / -0

    Diagrams such as cubes and cylinders are classified as

    Solution

    three dimensional diagrams

  • Question 3
    1 / -0

    Discrete variables and continuous variables are two types of

    Solution

    quantitative classification

  • Question 4
    1 / -0

    Which of the following is prepared by using class intervals and frequencies? 

    Solution

    These three can be prepared when data is given in the form of class intervals and corresponding frequencies. 

  • Question 5
    1 / -0

    In stem and leaf display diagrams used in exploratory analysis, stems are considered as

    Solution

    leading digits

  • Question 6
    1 / -0

    Classification method in which upper limit of interval is same as of lower limit class interval is called

    Solution

    exclusive method

  • Question 7
    1 / -0

    Smooth curve joining the points corresponding to the frequency and provides frequency curve of the data

    Solution

    The frequency curve is obtained by drawing a smooth freehand curve passing through the points of the frequency polygon as closely as possible. It may not necessarily pass through all the points of the frequency polygon but it passes through them as closely as possible. 

  • Question 8
    1 / -0

    A component part chart can be presented in the form of

    Solution

    A component part chart can be presented by circle through pie graph by converting the frequencies into angles and it also can be presented in the form of component bar graph by converting frequencies into percentage. 

  • Question 9
    1 / -0

    Graphic presentation of a cumulative frequency distribution is

    Solution

    Ogive is also called cumulative frequency curve. As there are two types of cumulative frequencies, for example "less than" type and "more than" type, accordingly there are two ogives for any grouped frequency distribution data.

  • Question 10
    1 / -0

    A frequency diagram records class frequencies I a frequency distribution. These include

    Solution

    Histograms, Frequency Polygons and Ogive can be prepared only if class intervals are given.  These can not be prepared from discrete data.
