Q1. Define
business research and explain the process of research?
Definition
of Research
Explanation
of the steps in a research study
Answer. Research
comprises "creative and
systematic work undertaken to increase the stock of knowledge, including
knowledge of humans, culture and society, and the use of this stock of
knowledge to devise new applications." It is used to establish or confirm
facts, reaffirm the results of previous work, solve new or existing problems,
support theorems, or develop new theories. A research project may also be an
expansion on past work in the field. Research projects can be used to develop
further knowledge on a topic, or in the example of a school research project,
they can be used to further a student's research prowe
Q2. What are
descriptive research designs? Explain the different kinds of descriptive
research designs.
Meaning of
Descriptive Research designs
Kinds of
Descriptive research designs
Answer. Descriptive
Research:
Sometimes an individual wants to know something about
a group of people. Maybe the individual is a would-be senator and wants to know
who they're representing or a surveyor who is looking to see if there is a need
for a mental health program.
Q3. Discuss
four types of measurements scales with appropriate examples.
Nominal
Ordinal
Interval
Ratio
Answer. Types
of measurements scales
Nominal
scale: Nominal
Nominal scales are used for labelling variables,
without any quantitative value.
“Nominal” scales could simply be called “labels.” Here are some examples, below. Notice that all of these scales are mutually
exclusive (no overlap) and none of them has any numerical significance. A good way to remember all of this is

Q1
Differentiate between the Stratified random sampling and Systematic sampling.
a.)
stratified random sampling
b.)
systematic sampling
Answer.
Systematic
sampling:
Systematic sampling is a type of probability sampling
method in which sample members from a larger population are selected according
to a random starting point and a fixed periodic interval. This interval, called
the sampling interval, is calculated by dividing the population size by the
desired sample size. Despite the sample population being selected in advance,
systematic sampling is still thought of as being random if the periodic
interval is determined beforehand and the starting point is random.
Since simply random sampling a population can be
inefficient and time-consuming, statisticians turn to other methods, such as
systematic sampling. Choosing a sample size through a systematic approach can
be done quickly. Once a fixed starting point has been identified, a constant
interval is selected to facilitate participant selection.
For example, if you wanted to select a random group of
1,000 people from a population of 50,000 using systematic sampling, all of the
potential participants must be placed in a list and a starting point would be
selected. Once the list is formed, every 50th person on the list, starting the
count at the selected starting point, would be chosen as a participant, since
50,000/1,000 = 50. For example, if the selected starting point was 20, the 70th
person on the list would be chosen followed by the 120th, and so on. Once the
end of the list was reached, if additional participants are required, the count
loops to the beginning of the list to finish the count.
One risk that statisticians must take into account
when conducting systematic sampling involves how the list used with the
sampling interval is organized. If the population placed on the list is
organized in a cyclical pattern that matches the sampling interval, the
selected sample may be biased. For example, a company's human resources
department wants to pick a sample of employees and ask how they feel about company
policies. Employees are grouped in teams of 20, with each team headed by a
manager. If the list used to pick the sample size is organized with teams
clustered together, the statistician risks picking only managers (or no
managers at all) depending on the sampling interval.
Q2. Distinguish
between coding closed-ended structured questions and coding open-ended
structured questions
Coding
Closed-ended
Coding
Open-ended
Answer. Coding
Closed-ended Structured Questions
A closed-ended question generates a limited set of
responses that can be coded easily in a database with some number or symbol
that represents a response.
Multiple-choice, ordinal, interval and ratio questions generate
closed-ended responses.
