Internal Practical – Home assignment for the second-semester students (Total marks: 30)

1. This is a practical problem of bivariate data analysis. In this problem first, you have to generate your own data by yourself. Then you have to find the association in your data. So, the first step is data generation.

Step 1- Data generation (instructions)

Select a book, select 20 pages randomly from that book. Now suppose your name is Animesh Mondal, thus your name is starting with “A” and ends with “L”. So you will count the number of “A” and “L” in each of those 20 pages.

If your name starts and ends with the same alphabet, e.g. if your name is Aditya Dutta then consider the second last alphabet of your name instead of the last alphabet of your name. In this case, the guy Aditya Dutta will count the number of "A" and "T" in each of 20 pages.

Step 2 – Answer the following questions

A) Once your data have been generated then find the correlation coefficient between the counts of two alphabets. Interpret the association between the counts of two alphabets with respect to the obtained value of the correlation coefficient.

B) Make a scatter plot of the data. What do think about the association between the counts of the two alphabets, after having the scatter plot?

C) Obtain the regression equations and draw them over the scatter plot. What do you think about the linear association between them?

Note: If you create your own data honestly then it is impossible that any two guys will have the same data set. So answer scripts with same data set will get cancelled.
