Q5. Discuss the importance of statistics in Economics?
Ans:
Statistics play an important role in economics. Economics largely depend upon statistics. National income accounts are multipurpose indicators for the economists and administrators. ii.

 Ans:

The  fundamental  differences  between  primary  and  secondary  data  are  discussed  in  the following  points:
i.  The  term  primary  data  refers  to  the  data  originated  by  the  researcher  for  the  first time.  Secondary  data  is  the  already  existing  data,  collected  by  the  investigator agencies  and  organizations  earlier.
ii.  Primary  data  collection  sources  include  surveys,  observations,  experiments, questionnaire,  personal  interview,  etc.  On  the  contrary,  secondary  data  collection sources  are  government  publications,  website,  books,  journal  article,  internal  records etc.
iii.  Data  collected  through  primary  sources  and  more  reliable  and  accurate  as  compared to  the  secondary  sources.
OR
What are the fundamental differences between bar chart and histogram?
Difference between Histograms and Bar Charts:
Bar Chart

  • The columns are positioned over a label that represents a categorical variable.
  • The height of the column indicates the size of the group defined by the categories.

Histogram

  • The columns are positioned over a label that represents a quantitative variable.
  • The column label can be a single value or a range of values.

Define median and find the median in the set of numbers given below:
15, 16, 15, 7, 21, 18, 19, 20, 11
OR
Median: The  median  is  defined  as  the  number  in  the  middle  of  a  given  set  of  numbers arranged  in  order  of  increasing  magnitude.  When  given  a  set  of  numbers,  the  median  is the  number  positioned  in  the  exact  middle  of  the  list  when  you  arrange  the  numbers from  the  lowest  to  the  highest.  The  median  is  also  a  measure  of  average.  In  higher  level statistics,  median  is  used  as  a  measure  of  dispersion.  The  median  is  important  because  if describes  the  behaviour  of  the  entire  set  of  numbers.
From  the  definition  of  median,  we  should  be  able  to  tell  that  the  first  step  is  to  rearrange the  given  set  of  numbers  in  order  of  increasing  magnitude,  i.e.  from  the  lowest  to  the highest 7,  11,  15,  15,  16,  18,  19,  20,  21
Then  we  inspect  the  set  of  find  that  number  which  lies  in  the  exact  middle.

In economics, the Lorenz Curve is a graphical representation of the distribution of income or of wealth. It was developed by Max O. Lorenz in 1905 for representing
inequality of the wealth distribution. The curve is a graph showing the proportion of overall income or wealth assumed by the bottom x% of the people, although this is not rigorously true for a finite population (see below).
It is often used to represent income distribution, where it shows for the bottom x% of households, what percentage (y%) of the total income they have. The percentage of  households is plotted on the x-axis, the percentage of income on the y-axis. It can also be used to show distribution of assets. In such use, many economists consider it to be a measure of social inequality.

Properties of Lorenz Curve:
1. A Lorenz curve always starts at (0,0) and ends at (1,1).
2. The Lorenz curve is not defined if the mean is zero or infinite.
3. The Lorenz curve for a distribution is a continuous function.
4. The information in a Lorenz curve may be summarized by the Gini coefficient.
5. The Lorenz curve cannot rise above the line of perfect quality.
