35. T-test is used when there is.....

Correct Answer: Correct answer is: (C) 1 dependent variable and 1 independent variable.

Exam Relevance: AP Statistics, GRE, GMAT, Psychology exams

Difficulty: Easy

Concept notes: A t-test is a statistical test used to determine if there is a significant difference between the means of two groups. It is typically used when comparing the means of a single dependent variable across two groups defined by a single independent variable.

Common Mistakes: Students often confuse the number of variables involved in a t-test, thinking it can involve multiple dependent or independent variables.

Explanations: A t-test is designed to compare the means of a single dependent variable between two groups. The independent variable in a t-test is typically a categorical variable with two levels (e.g., treatment vs. control). Therefore, the correct answer is that a t-test is used when there is 1 dependent variable and 1 independent variable.

Option Analysis:

Option A: Incorrect because a t-test does not involve 2 dependent variables.
Option B: Incorrect because a t-test does not involve 2 independent variables.
Option C: Correct because a t-test involves 1 dependent variable and 1 independent variable.
Option D: Incorrect because a t-test does not involve 2 dependent variables and 2 independent variables.

36. What is an attitude scale in which each item's value is calculated by finding out the mean or median of the ratings of a large number of judges on an eleven-point rating scale?

Correct Answer: Correct answer is: (C) Thurstone type.

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

Difficulty: Moderate

Concept notes: The Thurstone type attitude scale is a method where each item's value is determined by the mean or median of ratings provided by a large number of judges on an eleven-point rating scale.

Common Mistakes: Students may confuse the Thurstone type with the Likert type, which uses a forced-choice format rather than a rating scale.

Explanations: The Thurstone type attitude scale involves judges rating each item on an eleven-point scale. The mean or median of these ratings is then used to assign a value to each item. This method ensures that each item is placed on a continuum based on the judges' consensus, making it a reliable and valid measure of attitudes.

Option Analysis:

Option A: Guttman type is not correct because it involves a cumulative scale where items are arranged in a hierarchical order, not based on judges' ratings.
Option B: Likert type is not correct because it uses a forced-choice format (e.g., strongly agree to strongly disagree) rather than a rating scale.
Option C: Thurstone type is correct because it involves judges rating each item on an eleven-point scale, and the mean or median of these ratings is used to assign a value to each item.
Option D: Bogardus type is not correct because it is a social distance scale, which measures the willingness of individuals to engage in various social relationships with members of different groups.

Mnemonic: T-RATE: Thurstone Rating Attitude Test Evaluation
