Business Statistics and Research Methods MCQs

Assertion (A) Parametric test are applied initially.
Reason (R) Non-parametric test are much less cumbersome to use and easy to compute.

Match the groups of List-I with List-II and select the correct answer from the options given below

List-I	List-II
a. Index	1. General
b. Base year	2. $$\frac{{\sum RW}}{{\sum W}}$$
c. Index of the base year	3. Economic barometer
d. Family income-expenditure method	4. 100

The standard deviation of Bionomial distribution is:

Match the following items of List-I and List-II with regard to hypothesis-testing.

List-I	List-II
a. The ability of test to reject the null hypothesis when it is false	1. Level of significance
b. The probability of accepting a false null hypothesis	2. Type I error
c. The probability of rejecting a true null hypothesis due to sampling error	3. Type II error
d. The probability of rejecting a true null hypothesis	4. Power of a test

Select the methods of finding out correlation from the following.
1. Karl Pearson's Method
2. Spearman's Rank Method
3. Yule's Method
4. Coefficient of Contingency
5. Concurrent Deviation Method
Select the correct answer:

Assertion (A) The value, of coefficient of correlation shall always lie between -1 < r < +1.
Reason (R) When the value or r = +1 the correlation between the variable is perfect and positive and when r = -1, correlation is said to be perfect and negative.

The word 'statistics' is used as
OR
How the term statistics used?

In a Binomial Distribution, if p, q and n are probability of success, failure and number of trials respectively then given by:

Which of the following steps would be included in hypothesis testing?
1. State the null and alternative hypothesis.
2. Set the significance level before the research study.
3. Eliminate all outliers.
4. Obtain the probability value using a computer program such as SPSS.
5. Compare the probability value to the significance level and make the statistical decision.
