1334. A statistical test used to compare 2 or more group means is known as.....

Correct Answer: Correct answer is: (D) One-way analysis of variance.

Exam Relevance: AP Statistics, GRE Quantitative, Psychology Research Methods

Difficulty: Moderate

Concept notes: One-way analysis of variance (ANOVA) is a statistical test used to compare the means of two or more groups to determine if there are any statistically significant differences between them.

Common Mistakes: Students often confuse ANOVA with other statistical tests like t-tests, which are used to compare the means of only two groups.

Explanations: One-way ANOVA is specifically designed to compare the means of two or more groups. It assesses whether the observed differences in group means are due to chance or if they are statistically significant. This makes it the appropriate choice for comparing multiple group means.

Option Analysis:

Option A: T-test for correlation coefficients is used to test the significance of a correlation coefficient, not to compare group means.
Option B: Simple regression is used to model the relationship between a dependent variable and one independent variable, not to compare group means.
Option C: Post hoc tests are used after ANOVA to determine which specific groups differ from each other, but they are not the initial test to compare group means.
Option D: One-way analysis of variance is the correct choice for comparing the means of two or more groups.

Mnemonic: ANOVA: Analyze, Not One Variable Alone

Concept notes: A representative sample accurately reflects the characteristics of the population being studied, ensuring that the survey results can be generalized to the entire population.

Common Mistakes: Students often mistakenly believe that a larger sample size is more important than a representative sample, or that a biased sample can still yield valid results.

Explanations: Choosing a representative sample is crucial because it ensures that the survey results are unbiased and can be generalized to the entire population. A representative sample includes individuals who reflect the diversity of the population in terms of demographics, behaviors, and other relevant characteristics. This allows for accurate and reliable conclusions to be drawn from the survey data.

Option Analysis:

Option A: Correct. A representative sample ensures that the survey results are unbiased and can be generalized to the entire population.
Option B: Incorrect. While a larger sample size can increase the precision of the results, it is not as important as ensuring the sample is representative.
Option C: Incorrect. A biased sample will lead to skewed results that cannot be generalized to the population.
Option D: Incorrect. Choosing a sample whose answers will likely support a hypothesis introduces bias and undermines the validity of the survey.

Mnemonic: RepSample = ReliableSurvey

1339. Which scientific method often focuses on generating new hypotheses and theories?
