1138. Standard deviation is always computed from

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

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Easy

Concept notes: Standard deviation is a measure of the dispersion or spread of a dataset. It is calculated based on the mean of the dataset.

Common Mistakes: Students often confuse the measures of central tendency (mean, median, mode) and dispersion (standard deviation, variance). They may incorrectly assume that standard deviation can be computed from any measure of central tendency.

Explanations: Standard deviation is always computed from the mean because it measures the average distance of each data point from the mean. The formula for standard deviation involves subtracting the mean from each data point, squaring the differences, averaging these squared differences, and then taking the square root of this average. This process is directly dependent on the mean.

Option Analysis:

Option A: Standard deviation is not computed from the median. The median is the middle value in a dataset and does not factor into the calculation of standard deviation.
Option B: Standard deviation is computed from the mean. The mean is used in the formula to calculate the standard deviation.
Option C: Standard deviation is not computed from the geometric mean (GM). The geometric mean is a different measure of central tendency and is not used in the standard deviation formula.
Option D: Standard deviation is not computed from the mode. The mode is the most frequently occurring value in a dataset and is not used in the standard deviation formula.

1139. ..... is the most commonly used technique for controlling for extraneous variables in nonexperimental research.

Correct Answer: Correct answer is: (D) Statistical control.

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

Difficulty: Moderate

Concept notes: Statistical control is a method used in nonexperimental research to account for the influence of extraneous variables by using statistical techniques.

Common Mistakes: Students may confuse statistical control with other methods like matching or holding variables constant, which are less commonly used in nonexperimental research.

Explanations: Statistical control is the most commonly used technique for controlling for extraneous variables in nonexperimental research because it allows researchers to statistically adjust for the effects of these variables, thereby isolating the relationship between the independent and dependent variables. This method is particularly useful when it is not feasible to control extraneous variables through experimental manipulation or matching.

Option Analysis:

Option A: Matching involves pairing participants based on specific characteristics to control for extraneous variables, but it is not as commonly used as statistical control in nonexperimental research.
Option B: Holding extraneous variables constant is a method used in experimental research, not typically in nonexperimental research.
Option C: Static control is not a recognized term in the context of controlling for extraneous variables in nonexperimental research.
Option D: Statistical control is the correct answer as it is the most commonly used technique for controlling for extraneous variables in nonexperimental research.

1140. Target population is also called

Correct Answer: Correct answer is: (D) Survey population.

Exam Relevance: AP Statistics, GRE, GMAT, Research Methods Exams

Difficulty: Moderate

Concept notes: The target population is the specific group of individuals or items that a researcher aims to study and draw conclusions about. In survey research, this group is often referred to as the survey population.

Common Mistakes: Students may confuse the target population with the entire population, which includes all possible members of a group, or with the population frame, which is the list of all members of the target population from which the sample is drawn.

Explanations: The term "survey population" is used to denote the specific group of individuals or items that the survey aims to study. This aligns with the concept of the target population, which is the group of interest for the research. The other options do not specifically refer to the group being studied in a survey context.

Option Analysis:

Option A: Population refers to the entire group of individuals or items, not specifically the group being studied in a survey.
Option B: Population frame is the list of all members of the target population from which the sample is drawn, not the target population itself.
Option C: Population element refers to individual members of the population, not the group being studied.
Option D: Survey population correctly refers to the specific group of individuals or items being studied in a survey.
