Question. 1.Differentiate between correlation and regression.
Explain with suitable example using data.(10 Marks)

2. Answer:Correlation: In correlation analysis, we gauge an example Correlation coefficient, all the
more particularly the Pearson Product Moment Correlation coefficient. The specimen correlation
coefficient, meant r,
rangesbetween - 1 and+1 andevaluatesthe headingandqualityof the straightcorrelationbetween
the two variables.The Correlationbetween'stwovariablescanbe sure (i.e.,more elevated amounts
of one variable are connected with more elevated amounts of the other) or negative (i.e., more
elevated amounts of one variable are connected with lower levels of the other).
The indication of the correlation coefficient shows the course of the affiliation. The size of the
correlation coefficient shows the quality of the affiliation.
For instance, a correlation of r = 0.9 proposes a
Question.2. You want to find a measure of central tendency for
income of persons who have boarded aparticular train on a
particular date at the originating station. What measure will you
useand why? What measure will you choose for dispersion and
why? (10 marks)
Answer:Measuring: Surveying on the salary. In the event that I was you, I would enter trains of
various sorts to various time and Survey (quantitative survey). Remember that straightforwardly
getting some data about wage in the train may be translated off-base. So get some data about
differentthings,forexample,identity,time administration,kind of travel (get-aways, drive). Toward
the end to ask the "general inquiries" and among them the wage tendency.
Question.3. a)Distinguish between independence of events and
mutual exclusivity of events with thehelp of example. (5 marks)
Answer:Events are fundamentally unrelated if the event of one occasion bars the event of the
other(s).FundamentallyunrelatedEventscan'thappeninthe meantime.Forinstance:whileflipping
a coin, the outcome can either be Heads or Tails yet can't be both.
b)In how many ways can the letters of the word “MADAM” be
rearranged? (5 marks)

3. Answer:The rearrangementsof wordsallowsustofindmanyotherrelated words and when we talk
about the rearranged groups of “MADAM” then we will find the answer with the help of anagram.
Below is the anagram process and the answer of this question.
Step 1: Count the quantity of Letters you have (Answer: 5)
Step 2 : Get its factorial (meant by "!") in the numerator.
Step 3 : Get the Factorial of the rehashing letters in the denominator
5! /( 2! * 2!)
