1.
A hypothesis is
Correct Answer
A. A provisionally accepted hypothesis
Explanation
A provisionally accepted hypothesis refers to a hypothesis that is temporarily accepted until further evidence or experiments can either support or disprove it. This means that it is not yet proven or fully accepted as a scientific theory, but it is considered a starting point for further investigation. It is necessary to test a provisionally accepted hypothesis in order to gather more data and determine its validity.
2.
Questions need to be worded so that respondents expound on the topic, not just answer “ yes” or “no”
Correct Answer
A. Open ended questions
Explanation
Open ended questions are questions that do not have a specific answer and require the respondent to provide a detailed response. These types of questions allow for more in-depth exploration of a topic and provide the opportunity for the respondent to express their thoughts, feelings, and opinions. This can lead to a better understanding and interpretation of the topic being discussed. In a semi-structured format, open ended questions can be used to gather qualitative data and insights. It is important to record the responses to open ended questions accurately to ensure that the information provided by the respondents is captured correctly.
3.
A research paper
Correct Answer
B. Contains reviewed original research
Explanation
The correct answer is "contains reviewed original research." This answer is supported by the fact that a research paper is a scholarly document that presents the findings of an original study or investigation. The research contained in the paper has typically undergone a rigorous review process by experts in the field to ensure its quality and validity. This distinguishes it from a compilation of information on a topic, which may not necessarily involve original research. Additionally, a research paper is typically published in a single journal to avoid duplication and maintain the integrity of the research.
4.
In all these which is not a part of the research proposal?
Correct Answer
B. Hypothesis
Explanation
A hypothesis is not a part of a research proposal. A research proposal typically includes sections such as an introduction, literature review, research objectives, methodology, and expected outcomes. A hypothesis, on the other hand, is a statement that proposes a possible explanation for a phenomenon or a relationship between variables. While a hypothesis is an important component of the research process, it is not typically included in a research proposal as it is developed after the proposal is approved and the research is underway.
5.
Which type of longitudinal survey follows the same group of subjects over time?
Correct Answer
C. Panel
Explanation
A panel survey is a type of longitudinal survey that follows the same group of subjects over time. It involves collecting data from the same individuals at multiple points in time, allowing researchers to track changes and trends within the group. Panel surveys are valuable for studying long-term effects and capturing individual-level changes over time. This differs from trend surveys, which examine changes in different groups of people over time, cohort surveys that study specific age groups over time, and follow-up surveys that track individuals after a specific event or intervention.
6.
What type of research is used to test hypotheses about cause and effect issues?
Correct Answer
C. Causal Research
Explanation
Causal research is the type of research used to test hypotheses about cause and effect issues. This type of research aims to establish a cause-and-effect relationship between variables by manipulating one variable and observing the effects on another variable. It involves conducting experiments, collecting data, and analyzing the results to determine if there is a causal relationship between the variables under investigation. Causal research is particularly useful in fields such as medicine, psychology, and social sciences where understanding cause and effect relationships is essential for making informed decisions and developing interventions.

Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above". This means that all three hypotheses mentioned in the question are valid possibilities. It is possible that the new process is better than the old method, it is also possible that the old process is better than the new method, and it is also possible that there is no significant difference between the two processes. Without further information or evidence, we cannot determine which hypothesis is true.
8.
Most of the descriptive research tends to be which of the following types
Correct Answer
D. Large- scale survey type
Explanation
Descriptive research aims to describe and explain a phenomenon or population without manipulating variables. Large-scale survey type is the most common type of descriptive research, as it involves collecting data from a large sample size to generalize findings to a larger population. This type of research allows researchers to gather information from a diverse range of participants and obtain a comprehensive understanding of the topic under investigation. It provides statistical data that can be analyzed to identify patterns, trends, and relationships among variables. Therefore, large-scale survey type is the most suitable option for descriptive research.

7 – point rating scale with endpoints associated with bipolar labels that have sematic meaning is
Correct Answer
A. Semantic Differential Scale
Explanation
The Semantic Differential Scale is the correct answer because it is a rating scale that uses bipolar labels with semantic meaning. This means that the scale consists of opposite adjectives or phrases that represent different dimensions of the concept being measured. Respondents are asked to rate their perception or evaluation of the concept by indicating their position on the scale between the two endpoints. This scale is commonly used in psychology and social sciences to measure attitudes, opinions, or perceptions.

Techniques that allow several members of a hiring company to interview a job candidate at the same time is
Correct Answer
B. Panel Interview
Explanation
A panel interview is a technique that allows several members of a hiring company to interview a job candidate at the same time. This type of interview is commonly used to assess a candidate's skills, knowledge, and fit for a particular role. It provides a comprehensive evaluation as multiple perspectives are considered during the interview process. The panel interview allows for a more thorough assessment of the candidate's qualifications and ensures that different viewpoints are taken into account when making a hiring decision.
11.
A simple random sample is one in which
Correct Answer
C. Every unit of the population has an equal chance of being selected
Explanation
In a simple random sample, every unit of the population has an equal chance of being selected. This means that each member of the population has the same probability of being chosen to be part of the sample. This ensures that the sample is representative of the entire population, as each unit has an equal opportunity to be included. This method helps to minimize bias and increase the generalizability of the results to the larger population.
12.
The most common scales used in business research are
Correct Answer
D. All of the above
Explanation
The statement "All of the above" indicates that all the options mentioned (Nominal, Ratio, and Ordinal) are correct and commonly used scales in business research. Nominal scale is used to categorize data into distinct categories, Ratio scale is used to measure data with a meaningful zero point, and Ordinal scale is used to rank or order data. Therefore, all three scales are commonly used in business research.
13.
Which of the following is not a type of non-probability sampling?
Correct Answer
A. Stratified random sampling
Explanation
Stratified random sampling is not a type of non-probability sampling because it involves dividing the population into subgroups or strata and then randomly selecting participants from each stratum. This method ensures that each subgroup is represented in the sample proportionally to its size in the population. In contrast, non-probability sampling methods, such as snowball sampling, quota sampling, and convenience sampling, do not involve random selection and may introduce bias into the sample.
14.
A sampling frame is:
Correct Answer
A. List of all the units in the population from which a sample will be selected
Explanation
A sampling frame refers to a list of all the units in the population from which a sample will be selected. This list serves as a reference for researchers to ensure that every unit in the population has an equal chance of being included in the sample. It provides a comprehensive and organized representation of the population, allowing researchers to select a representative sample that can accurately reflect the characteristics of the entire population.
15.
The standard error is a statistical measure of:
Correct Answer
B. The extent to which a sample mean is likely to differ from the population mean
Explanation
The standard error is a statistical measure that quantifies the variability or uncertainty in the sample mean compared to the population mean. It provides an estimate of how much the sample mean is expected to deviate from the true population mean. In other words, it measures the precision or accuracy of the sample mean as an estimate of the population mean. A smaller standard error indicates a more reliable estimate of the population mean, while a larger standard error suggests a greater likelihood of the sample mean differing from the population mean.
16.
Why do you need to review the existing literature?
Correct Answer
B. To find out what is already known about your area of interest
Explanation
Reviewing the existing literature is necessary to find out what is already known about your area of interest. This helps to avoid duplicating previous research and allows you to build upon existing knowledge. It also helps to identify any gaps in the current understanding, which can guide the direction of your own research. Additionally, reviewing the literature provides a solid foundation for your study and allows you to contextualize your research within the existing body of knowledge.
17.
A systematic literature review is:
Correct Answer
C. A replicable, scientific and transparent process
Explanation
A systematic literature review is a replicable, scientific, and transparent process. This means that it follows a clearly defined methodology that can be replicated by others, it is based on scientific principles and rigorous research methods, and it is conducted in a transparent manner, with all steps and decisions documented and made available for scrutiny. This ensures that the review is reliable, credible, and unbiased, and that its findings can be trusted by the research community.

Correct Answer
D. They are all equally important
Explanation
Each of these steps plays a crucial role when accessing the internet. Recording the full URL ensures that the specific webpage or resource can be easily referenced or revisited. Noting the access dates helps in keeping track of when the information was accessed, which is important for citing sources and ensuring the accuracy of information. Downloading material to be referenced allows for offline access and ensures that the information will still be available even if the webpage or resource is no longer accessible online. Overall, all these steps are equally important for efficient and effective internet usage.
20.
What is the difference between a bar chart and a histogram?
Correct Answer
D. There are no gaps between the bars on a histogram
Explanation
A histogram is a type of bar chart that is used to represent the distribution of a continuous variable. Unlike a regular bar chart, a histogram does not have any gaps between the bars. Instead, the bars in a histogram touch each other to show the continuous nature of the variable being represented. This is because a histogram is used to display the frequency or count of data within specific intervals or bins, rather than representing individual data points. Therefore, the absence of gaps between the bars on a histogram is a key difference between a histogram and a regular bar chart.
