114. Sequence of steps in scientific method is

Correct Answer: Correct answer is: (D) Observation-hypotheses-experiments-theory-establishment of law.

Exam Relevance: AP Biology, AP Chemistry, IB Science, SAT Subject Tests

Difficulty: Moderate

Concept notes: The scientific method is a systematic process used to explore observations and answer questions. It involves making observations, formulating hypotheses, conducting experiments, developing theories, and establishing laws.

Common Mistakes: Students often confuse the order of steps in the scientific method, particularly the sequence between observation and hypothesis.

Explanations: The correct sequence starts with making observations about a phenomenon. Based on these observations, a hypothesis is formulated. Experiments are then conducted to test the hypothesis. If the experiments support the hypothesis, a theory may be developed. Over time, if the theory is consistently supported by evidence, it may be established as a scientific law.

Option Analysis:

Option A: Incorrect because it starts with experiments, which should follow observations and hypotheses.
Option B: Incorrect because it skips the hypothesis step, which is crucial before experiments.
Option C: Incorrect because it starts with hypotheses, which should follow observations.
Option D: Correct because it follows the proper sequence of the scientific method.

Mnemonic: Observe, Hypothesize, Experiment, Theorize, Law (O-H-E-T-L)

115. The use of multiple data sources to help understand a phenomenon is one strategy that is used to promote qualitative research validity. Which of the following terms describes this strategy?

Correct Answer: Correct answer is: (C) Data triangulation.

Exam Relevance: Qualitative Research Methods, Research Methodology, Social Science Research

Difficulty: Moderate

Concept notes: Data triangulation is a method used in qualitative research to enhance the validity of findings by using multiple data sources or methods to cross-check and corroborate the information.

Common Mistakes: Students may confuse data triangulation with other data validation techniques, such as data matching or pattern matching, which do not involve multiple sources.

Explanations: Data triangulation involves collecting data from different sources, methods, or perspectives to ensure that the findings are consistent and reliable. This approach helps to reduce bias and increase the credibility of the research. The term "triangulation" refers to the use of multiple angles or perspectives to arrive at a more accurate understanding of the phenomenon being studied.

Option Analysis:

Option A: Data matching is not a recognized term in qualitative research and does not involve the use of multiple data sources.
Option B: Data feedback typically refers to the process of sharing research findings with participants for their input, not a method for enhancing validity through multiple data sources.
Option C: Data triangulation is the correct term for using multiple data sources to enhance the validity of qualitative research findings.
Option D: Pattern matching involves identifying patterns in data but does not necessarily involve multiple data sources to enhance validity.

116. The use of the laws of probability to make inferences and draw statistical conclusions about populations based on sample data is referred to as.....

Correct Answer: Correct answer is: (B) Inferential statistics.

Exam Relevance: AP Statistics, GRE, GMAT, MCAT

Difficulty: Moderate

Concept notes: Inferential statistics involves using sample data to make inferences about a larger population.

Common Mistakes: Students may confuse inferential statistics with descriptive statistics, which only summarize sample data without making inferences about the population.

Explanations: Inferential statistics is the correct answer because it specifically refers to the use of probability laws to make inferences and draw conclusions about populations based on sample data. This process involves statistical methods such as hypothesis testing, confidence intervals, and regression analysis to generalize findings from a sample to a larger population.

Option Analysis:

Option A: Population statistics refers to the study of entire populations, not the use of sample data to infer population characteristics.
Option B: Inferential statistics is the correct term for using sample data to make inferences about populations.
Option C: Sample statistics refers to the summary measures of a sample, not the process of making inferences about a population.
Option D: Descriptive statistics involves summarizing and describing the features of a dataset, but does not involve making inferences about a population.

117. Qualitative approach to research is concerned with the subjective assessment of

Correct Answer: Correct answer is: (D) Attitudes, opinions and behavior.

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Social Science Exams

Difficulty: Moderate

Concept notes: Qualitative research focuses on understanding subjective experiences and meanings.

Common Mistakes: Students may confuse qualitative research with quantitative research, which focuses on numerical data.

Explanations: Qualitative research is concerned with understanding the subjective experiences, attitudes, opinions, and behaviors of individuals. This approach aims to capture the depth and complexity of human experiences, often through methods such as interviews, focus groups, and observations. The subjective assessment of attitudes, opinions, and behavior aligns with the core principles of qualitative research.

Option Analysis:

Option A: Research problems are identified in both qualitative and quantitative research, but qualitative research does not solely focus on the problems themselves.
Option B: Research methods are used in qualitative research, but the focus is not on the methods themselves but on the data collected through these methods.
Option C: Data, analysis, and interpretation are part of qualitative research, but the emphasis is on the subjective content of the data rather than the process of analysis and interpretation.
Option D: Attitudes, opinions, and behavior are the core focus of qualitative research, as it aims to understand the subjective experiences of individuals.

Concept notes: A research plan typically includes several key components such as objectives, a review of literature, and a research hypothesis.

Common Mistakes: Students may overlook the importance of a review of literature or the necessity of a research hypothesis in a comprehensive research plan.

Explanations: A research plan is a structured outline that guides the research process. It includes defining the objectives of the study, reviewing existing literature to understand the context and previous findings, and formulating a research hypothesis to test specific predictions. Each of these components is essential for a well-rounded research plan, making "All of these" the correct answer.

Option Analysis:

Option A: Objectives of the study are a critical part of a research plan as they define the goals and scope of the research.
Option B: Review of literature is important to establish the research context and identify gaps in existing knowledge.
Option C: Research hypothesis is necessary to guide the research design and data analysis.

120. A researcher divides the populations into PG, graduates and 10+2 students and using the random digit table he selects some of them from each. This is technically called.

Correct Answer: Correct answer is: (B) Stratified random sampling.

Exam Relevance: Statistics exams, Research Methods exams, Social Science exams

Difficulty: Moderate

Concept notes: Stratified random sampling involves dividing the population into distinct subgroups (strata) and then randomly selecting samples from each subgroup.

Common Mistakes: Students may confuse stratified random sampling with simple random sampling, where the entire population is treated as a single group.

Explanations: The researcher divides the population into distinct groups (PG, graduates, and 10+2 students) and then selects some individuals from each group using a random method. This approach ensures that each subgroup is represented in the sample, which is the essence of stratified random sampling.

Option Analysis:

Option A: Settled sampling is not a recognized term in sampling methods.
Option B: Stratified random sampling is the correct term for the described method.
Option C: Representative sampling is a general term and does not specify the stratified approach.
