(Meaning – 2
marks, Functions – 3 marks, Applications - 5 marks)
Answer: :-
Statistics- Statistics as a discipline is
the development and application of methods to collect, analyze and interpret
data. Modern statistical methods involve the design and analysis of experiments
and surveys, the quantification of biological, social and scientific phenomenon
and the application of statistical principles to understand more about the
world around us.
Q2.
a) Explain the
approaches to define probability.
b) State the addition and
multiplication rules of probability giving an example of each case.
Answer:
a.
Approaches
to define Probability
There
are four approaches to define Probability. They are as follows:
1)
Classical / mathematical / priori approach
2)
Statistical / relative frequency / empirical / posteriori approach
Q3.
a)
The procedure of testing hypothesis requires a researcher to adopt several
steps. Describe in brief all such steps.
b)
Explain the components of time series.
Answer.
a.
Steps
for procedure of testing hypothesis
Five Steps in Hypothesis
Testing:
- Specify the Null Hypothesis
- Specify the
Alternative Hypothesis
- Set the
Significance Level (a)
Q4. a. What is a Chi-square test?
Point out its applications. Under what conditions is this test applicable?
(Meaning of Chi-square test, Applications, Conditions)
b) Discuss the types
of measurement scales with examples.
Answer:
a.
The Chi-square test is one of the
most commonly used non-parametric tests in statistical work. The Greek Letter c2
is used to denote
this test. c2 describe the magnitude of discrepancy between the observed
and the expected frequencies. The value of
c2 is calculated as:

(Meaning of Analysis of Variance, Assumptions,
Formulas/Calculation/Solution to the problem) 2, 1, 7
Answer:
Analysis of
variance (ANOVA)
It is a collection of statistical models used to analyze the differences
between group means and their associated procedures (such as
"variation" among and between groups). In ANOVA setting, the observed
variance in a particular variable is partitioned into components attributable
to different sources of variation. Get fully solved assignment, plz
