523. Identify what type of Qualitative Research is the topic:Child rearing practices of Bajao

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

Exam Relevance: Anthropology exams, Sociology exams, Cultural Studies exams

Difficulty: Moderate

Concept notes: Ethnographic research involves the study of a culture or community, often through participant observation and detailed descriptions of social practices.

Common Mistakes: Students may confuse ethnographic research with phenomenological research, which focuses on understanding the lived experiences of individuals.

Explanations: Ethnographic research is the most appropriate method for studying child rearing practices of the Bajao community. This approach involves immersing oneself in the community to observe and document their cultural practices, beliefs, and social interactions related to child rearing. Ethnography aims to provide a comprehensive understanding of the cultural context and practices of a specific group.

Option Analysis:

Option A: Phenomenological research focuses on understanding the subjective experiences of individuals, which is not the primary focus of studying child rearing practices of a community.
Option B: Ethnographic research is the correct choice as it involves studying the cultural practices and social interactions of a community, which aligns with the study of child rearing practices of the Bajao.
Option C: Grounded theory involves developing a theory through systematic collection and analysis of data, which is not the primary focus of studying child rearing practices of a community.

Correct Answer: Correct answer is: (D) Ratio Scale.

Exam Relevance: Psychology exams, Statistics exams, Research Methods exams

Difficulty: Moderate

Concept notes: A ratio scale is a type of measurement scale that has a true zero point, meaning that zero represents the absence of the quantity being measured.

Common Mistakes: Students often confuse the ratio scale with the interval scale, which does not have a true zero point.

Explanations: The ratio scale includes a true zero point, which means that zero indicates the complete absence of the quantity being measured. This is a key characteristic that distinguishes the ratio scale from other scales like the interval scale, which lacks a true zero point.

Option Analysis:

Option A: A rating scale does not have a true zero point and is used to measure subjective opinions or attitudes.
Option B: An interval scale has equal intervals between values but does not have a true zero point, meaning that zero does not indicate the absence of the quantity.
Option C: An ordinal scale ranks items in order but does not have a true zero point or equal intervals between values.
Option D: A ratio scale has a true zero point, which means that zero indicates the absence of the quantity being measured.

Mnemonic: Remember: Ratio has a Real Zero.

527. Which is plural for mouse?

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

Exam Relevance: SAT, ACT, TOEFL, IELTS

Difficulty: Easy

Concept notes: The plural form of "mouse" is "mice."

Common Mistakes: Students often confuse the plural form of "mouse" with "mouses," which is incorrect.

Explanations: The word "mouse" is an irregular noun in English. Its plural form is "mice," not "mouses." This is a common exception to the general rule that plurals are formed by adding "s" or "es" to the singular form.

Option Analysis:

Option A: Incorrect. "Mouses" is not the correct plural form of "mouse."
Option B: Correct. "Mice" is the correct plural form of "mouse."
Option C: Incorrect. "Mousees" is not a valid plural form of "mouse."
Option D: Incorrect. "Apples" is unrelated to the plural form of "mouse."

528. What is an antecedent?

Correct Answer: Correct answer is: (D) The word the pronoun is replacing.

Exam Relevance: SAT, ACT, TOEFL, IELTS

Difficulty: Easy

Concept notes: An antecedent is the noun or noun phrase that a pronoun refers to in a sentence.

Common Mistakes: Students often confuse antecedents with other parts of speech, such as adjectives or verbs.

Explanations: The correct answer is that an antecedent is the word the pronoun is replacing. In a sentence, a pronoun takes the place of a noun, and the noun it replaces is called the antecedent.

Option Analysis:

Option A: This option describes a noun, not an antecedent.
Option B: This option describes a verb, not an antecedent.
Option C: This option describes an adjective, not an antecedent.
Option D: This option correctly defines an antecedent as the word the pronoun is replacing.

Mnemonic: Pronoun Points to Previous Noun

529. Kristine choose ABM 1 as the treatment group and ABM 2 as another group as the respondents of her study. What type of quasi - experimental research did she used?

Correct Answer: Correct answer is: (C) Matched Comparison.

Exam Relevance: Research Methods, Psychology Exams, Statistics Exams

Difficulty: Moderate

Concept notes: Matched comparison is a type of quasi-experimental design where two groups are compared, and efforts are made to ensure that the groups are similar in all respects except for the treatment.

Common Mistakes: Students may confuse matched comparison with time series, which involves repeated measurements over time, or single subject quasi-experimental designs, which focus on individual cases.

Explanations: In Kristine's study, she chose ABM 1 as the treatment group and ABM 2 as another group. This indicates that she is comparing two groups that are matched or similar in all respects except for the treatment. This aligns with the definition of matched comparison, where the goal is to control for confounding variables by matching the groups on key characteristics.

Option Analysis:

Option A: Time series involves repeated measurements over time, which is not applicable here.
Option B: Single Subject Quasi involves studying individual cases, not comparing groups.
Option C: Matched Comparison involves comparing two groups that are matched on key characteristics, which fits the scenario described.
Option D: Matched Comparison and Time Series would involve both comparing groups and repeated measurements over time, which is not the case here.

530. Which of the following designs permits a comparison of pretest scores to determine the initial equivalence of groups on the pretest before the treatment variable is introduced into the research setting.

Correct Answer: Correct answer is: (B) Pretest-posttest control group design.

Exam Relevance: Psychology exams, Research Methods exams, Statistics exams

Difficulty: Moderate

Concept notes: The pretest-posttest control group design allows researchers to compare pretest scores between the experimental and control groups to ensure initial equivalence before the treatment is introduced.

Common Mistakes: Students may confuse the one-group pretest-posttest design with the pretest-posttest control group design, as both involve pretests. However, the latter includes a control group for comparison.

Explanations: The pretest-posttest control group design includes both a control group and an experimental group. By comparing pretest scores between these groups, researchers can determine if the groups were initially equivalent before the treatment is introduced. This is crucial for ensuring that any observed differences in posttest scores can be attributed to the treatment rather than pre-existing differences.

Option Analysis:

Option A: The one-group pretest-posttest design does not include a control group, so it cannot be used to compare pretest scores between groups.
Option B: The pretest-posttest control group design includes both a control group and an experimental group, allowing for the comparison of pretest scores to establish initial equivalence.
Option C: The posttest-only design with nonequivalent groups does not include pretests, so it cannot be used to compare pretest scores.
Option D: This option is incorrect because only the pretest-posttest control group design allows for the comparison of pretest scores.
