592. Which two types of calculations are descriptive statistics designed to interpret?

Correct Answer: Correct answer is: (D) Only (A) & (B).

Exam Relevance: AP Statistics, GRE, GMAT, MCAT

Difficulty: Moderate

Concept notes: Descriptive statistics are used to summarize and describe the features of a dataset. They include measures of central tendency (averages) and measures of variability (spread).

Common Mistakes: Students may mistakenly include effect size as a descriptive statistic, which is actually a measure used in inferential statistics to quantify the magnitude of an effect.

Explanations: Descriptive statistics are designed to interpret averages and measures of spread. Averages, such as the mean, median, and mode, provide information about the central tendency of the data. Measures of spread, such as the range, variance, and standard deviation, provide information about the dispersion of the data. Effect size, on the other hand, is a measure used in inferential statistics to quantify the magnitude of an effect, not a descriptive statistic.

Option Analysis:

Option A: Averages are a type of descriptive statistic that measures central tendency.
Option B: Measures of spread are a type of descriptive statistic that measures variability.
Option C: Effect size is not a descriptive statistic; it is used in inferential statistics.
Option D: Only (A) & (B) are correct as they are the types of calculations that descriptive statistics are designed to interpret.

593. The development of a solid foundation of reliable knowledge typically is built from which type of research?

Correct Answer: Correct answer is: (B) Basic research.

Exam Relevance: GRE, MCAT, PhD Qualifying Exams

Difficulty: Moderate

Concept notes: Basic research is aimed at expanding knowledge and understanding of fundamental principles, which forms the foundation for more applied research and practical applications.

Common Mistakes: Students may confuse basic research with applied research, which focuses on solving specific problems rather than expanding fundamental knowledge.

Explanations: Basic research is the type of research that aims to expand the fundamental knowledge and understanding of a field. It is not driven by immediate practical applications but rather by the pursuit of knowledge for its own sake. This foundational knowledge is crucial for the development of reliable and robust scientific theories and principles, which can then be applied in various practical contexts.

Option Analysis:

Option A: Action research is typically focused on solving practical problems within specific contexts, rather than building a foundational knowledge base.
Option B: Basic research is aimed at expanding fundamental knowledge and understanding, which is essential for developing a solid foundation of reliable knowledge.
Option C: Orientational research is not a standard term in research methodology and does not refer to a recognized type of research.
Option D: Evaluation research is focused on assessing the effectiveness of programs or interventions, rather than building foundational knowledge.

594. Action research hypothesis is

Correct Answer: Correct answer is: (C) Written in two parts-one is goal put second is action part.

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Action Research Certification

Difficulty: Moderate

Concept notes: Action research hypothesis is structured to guide a specific intervention or action aimed at solving a particular problem or achieving a goal.

Common Mistakes: Students often confuse action research hypotheses with those used in pure sciences, which are more general and not action-oriented.

Explanations: Action research hypotheses are unique because they are designed to be actionable and goal-oriented. They consist of two parts: the first part outlines the goal or desired outcome, and the second part describes the specific action or intervention that will be taken to achieve that goal. This structure ensures that the research is directly linked to practical outcomes and interventions.

Option Analysis:

Option A: Action research hypotheses are not general in nature; they are specific to the context and problem at hand.
Option B: Action research hypotheses differ from those in pure sciences as they are action-oriented and specific to a particular context.
Option C: This is correct because action research hypotheses are structured in two parts: the goal and the action.
Option D: While it is a hypothesis, it is not in the traditional sense used in pure sciences; it is specifically designed for action research.

Mnemonic: Goal-Action, GA

595. If a research finding is statistically significant, then.....

Correct Answer: Correct answer is: (B) The observed result is probably not due to chance.

Exam Relevance: AP Statistics, GRE, MCAT, GMAT

Difficulty: Moderate

Concept notes: Statistical significance indicates that the probability of the observed result occurring by chance is very low.

Common Mistakes: Students often confuse statistical significance with practical significance, thinking that a statistically significant result is always meaningful in a real-world context.

Explanations: Statistical significance is determined by a p-value, which measures the probability that the observed result is due to random chance. If the p-value is below a predetermined threshold (commonly 0.05), the result is considered statistically significant, meaning it is unlikely to have occurred by chance alone.

Option Analysis:

Option A: This is incorrect because statistical significance implies that the result is not likely due to chance.
Option B: This is correct because statistical significance indicates that the observed result is probably not due to chance.
Option C: This is incorrect because statistical significance suggests that the null hypothesis is likely false, not true.
Option D: This is incorrect because while the result is unlikely to be due to chance, it is not impossible.

596. Ethical Neutrality is a feature of

Correct Answer: Correct answer is: (C) Scientific method.

Exam Relevance: GRE, MCAT, LSAT

Difficulty: Moderate

Concept notes: Ethical neutrality refers to the absence of bias or moral judgment in a process or method. In the context of scientific research, ethical neutrality is crucial to ensure that the results are objective and not influenced by personal or societal values.

Common Mistakes: Students may confuse ethical neutrality with the idea that science is value-free, which is not entirely accurate. Science can be influenced by societal values and ethical considerations, but the scientific method itself aims to be neutral.

Explanations: The scientific method is designed to be objective and free from personal biases or ethical judgments. This neutrality is essential for ensuring that scientific findings are based on empirical evidence rather than subjective opinions. The other options (Experience, Deduction, and Observation) do not inherently guarantee ethical neutrality as they can be influenced by personal or societal values.

Option Analysis:

Option A: Experience can be subjective and influenced by personal biases.
Option B: Deduction can be influenced by the premises and assumptions used, which may not be ethically neutral.
Option C: The scientific method is designed to be objective and free from ethical biases.
Option D: Observation can be influenced by the observer's perspective and biases.

597. These refers to a systematized knowledge of inquiry by defining and redefining problems, formulating hypothesis, or suggested solutions: collecting, organizing and evaluating data; making deductions and reaching conclusions; and at last carefully testing the conclusions to determine whether they fit the formulating hypothesis.
