Explanations: Standard deviation measures how spread out the data points are from the mean. It is a measure of dispersion, unlike mean, mode, and median which are measures of central tendency.

Option Analysis:

Option A: Mean is a measure of central tendency, not dispersion.
Option B: Standard deviation is a measure of dispersion.
Option C: Mode is a measure of central tendency, not dispersion.
Option D: Median is a measure of central tendency, not dispersion.

264. A hypothesis is not the research answer , but rather

Correct Answer: Correct answer is: (B) A proposal to be tested and evaluated.

Exam Relevance: GRE, MCAT, GMAT, Undergraduate Research Methods Exams

Difficulty: Moderate

Concept notes: A hypothesis is a statement that proposes a possible explanation for a phenomenon or observation. It is not the final answer to a research question but rather a tentative explanation that can be tested and evaluated through experiments or further research.

Common Mistakes: Students often confuse a hypothesis with a theory, which is a well-substantiated explanation for a set of related phenomena. A hypothesis is a more preliminary step in the scientific process.

Explanations: A hypothesis is a proposal that can be tested and evaluated through research methods. It is not a final answer or a theory, but rather a statement that can be examined to determine its validity. This aligns with the correct answer, which states that a hypothesis is a proposal to be tested and evaluated.

Option Analysis:

Option A: A hypothesis is not a theory to be tested, but rather a proposal that can be tested and evaluated.
Option B: This is the correct answer as a hypothesis is a proposal that can be tested and evaluated through research methods.
Option C: A hypothesis is not imaginary terms or situations, but a specific statement that can be tested.
Option D: A hypothesis is not an assumption in a thesis, but a specific statement that can be tested and evaluated.

Mnemonic: Hypothesis: Propose, Test, Evaluate

265. Cumulative frequency curve is known as

Correct Answer: Correct answer is: (B) Ogive.

Exam Relevance: SAT, ACT, AP Statistics, IB Mathematics

Concept notes: A cumulative frequency curve, also known as an ogive, is a graphical representation of the cumulative frequency distribution.

Common Mistakes: Students may confuse the ogive with a frequency polygon, which is a line graph that connects the midpoints of the tops of the bars in a histogram.

Explanations: The cumulative frequency curve, or ogive, is a plot of the cumulative frequency against the upper class boundary with the points joined by a smooth curve. It is used to determine the number of observations that lie below a particular value.

Option Analysis:

Option A: A frequency polygon is a line graph that connects the midpoints of the tops of the bars in a histogram, not a cumulative frequency curve.
Option B: An ogive is the correct term for a cumulative frequency curve.
Option C: Hysterogram is not a standard term in statistics and is not related to cumulative frequency curves.
Option D: A histogram is a graphical representation of data using bars of different heights, not a cumulative frequency curve.

Mnemonic: Ogive: "O" for "Overall" frequency.

266. Which of the following is an example of deception in business research?

Correct Answer: Correct answer is: (D) The researcher representing their research as being about a different topic.

Exam Relevance: Business Ethics, Research Methods, MBA Exams

Difficulty: Moderate

Concept notes: Deception in business research involves misleading participants about the true nature or purpose of the study.

Common Mistakes: Students may confuse deception with other forms of unethical behavior, such as unauthorized access to company materials.

Explanations: Deception in research occurs when participants are misled about the true purpose or nature of the study. Representing the research as being about a different topic is a form of deception because it involves intentionally misleading participants about the actual focus of the research.

Option Analysis:

Option A: Obtaining company material without permission is an example of unauthorized access, not deception.
Option B: Wearing a disguise during an observation is a method of concealment, not deception.
Option C: Failing to ask permission to interview someone is an ethical issue related to consent, not deception.
Option D: Representing the research as being about a different topic is a form of deception because it involves misleading participants about the true nature of the study.

267. When a research problem is related to heterogeneous population, the most suitable sampling method is:

Correct Answer: Correct answer is: (C) Stratified Sampling.

Exam Relevance: AP Statistics, GRE, GMAT, MCAT

Difficulty: Moderate

Concept notes: Stratified sampling is a method where the population is divided into distinct subgroups (strata) based on specific characteristics, and samples are then taken from each stratum. This method is particularly useful when dealing with a heterogeneous population, as it ensures that each subgroup is adequately represented in the sample.

Common Mistakes: Students often confuse stratified sampling with cluster sampling, where the population is divided into clusters and entire clusters are randomly selected. However, in stratified sampling, samples are taken from each stratum, ensuring representation from all subgroups.

Explanations: Stratified sampling is the most suitable method for a heterogeneous population because it ensures that each subgroup within the population is represented in the sample. This method allows for more accurate and reliable results by reducing sampling error and ensuring that the sample reflects the diversity of the population.

Option Analysis:

Option A: Convenient Sampling is not suitable for a heterogeneous population as it relies on convenience and may not adequately represent all subgroups.
Option B: Lottery Method is a form of simple random sampling and does not account for the heterogeneity of the population.
Option C: Stratified Sampling is the correct choice as it ensures representation from all subgroups within a heterogeneous population.
Option D: Cluster Sampling involves selecting entire clusters, which may not ensure representation from all subgroups within a heterogeneous population.

268. Which one of the following is a research tool?

Correct Answer: Correct answer is: (A) Questionnaire.
