Types of Data
Data serves as the foundation for research and decision-making. It can be broadly categorized
into two types: primary data and secondary data.
Primary Data is original and collected firsthand by the researcher for a specific purpose. It is
tailored to meet the unique needs of a study, ensuring relevance and accuracy. For example,
data collected through surveys, interviews, or experiments falls under this category. Since
primary data is specific to the research objectives, it is highly reliable but often requires
significant time and resources to collect.
Secondary Data, on the other hand, is pre-existing information that has been collected,
3.Discuss various types of questions in questionnaire and their need in questionnaire. 10
Ans 3.
Types of Questions in a Questionnaire and Their Role
A questionnaire is a structured tool used to gather information from respondents
systematically. It comprises different types of questions, each serving a specific purpose to
ensure the research objectives are met. The selection of question types significantly impacts
the quality and depth of the data collected.
1. Open-Ended Questions Open-ended questions allow respondents to answer in their own

Ans 5.
Research Proposals and Reports: Significance and Components
Research proposals and reports are integral to the research process, serving distinct but
complementary roles. A research proposal outlines the objectives, methodology, and
significance of a study, acting as a blueprint for the research. It is typically prepared before
the research begins and is used to secure funding, approval, or support. On the other hand, a
research report presents the findings, analysis, and conclusions of the completed research,
6. A random sample of 395 people in a country were surveyed to find out if gender is
independent of education level. Each person was asked to report on the highest
education level they had obtained. The data that resulted from the survey is
summarized in the following table:
Formulate the hypothesis and test that are gender and education level dependent at 5%
level of statistical significance? 2+8
Ans 6.
Hypothesis Testing for Gender and Education Level
Step 1: Formulating Hypotheses
1. Null Hypothesis (H₀): Gender and education level are independent.
2. Alternative Hypothesis (Hₐ): Gender and education level are not independent.
Step 2: Given Data
The observed data is as follows:
Gender High School Bachelor’s Master’s PhD Row Total
Male 60 54 46 41 201
Female 54 60 41 39 194
Column Total 114 114 87 80 395
Step 3: Calculation of Expected Frequencies
The formula for expected frequencies (Eij) is:
High School Bachelors Masters Ph.D. Total
Female 60 54 46 41 201
Male 40 44 53 57 194
Total 100 98 99 98 395
Eij =
(Row Total for i) × (Column Total for j)
