Accepted Answer

The answer of Please conceptualize child abuse (or another abstract...

Question 2

Professor Smith gave the class an exam on Monday. On Wednesday Professor Smith gave the same class the same exam. Professor Smith was clearly interested in assessing the exam's:

Accepted Answer

By giving the same exam to the same class twice, Professor Smith is checking the consistency and stability of the exam results, which is an assessment of the exam's reliability. Validity refers to whether the exam measures what it is intended to measure, face validity refers to whether the exam appears to measure what it is intended to measure to the test-takers, conceptualization refers to defining the key concepts being measured by the exam, and precision refers to the level of detail or accuracy in the exam.

Question 3

The specification of concepts in scientific inquiry depends on:

Accepted Answer

The answer of The specification of concepts in scientific inquiry...

Question 4

A nominal definition:

Accepted Answer

A nominal definition is a statement that assigns a definition to a concept. It is a statement that provides a meaning to a term or concept that allows us to have a common understanding of what it refers to.

Question 5

A level of measurement describing a variable whose attributes are rank-ordered and have equal distances between adjacent attributes are _____ measures.

Accepted Answer

This level of measurement is known as interval measurement. It is characterized by equal distances between adjacent attributes, and the attributes are also rank-ordered like in ordinal measurement. However, unlike ordinal measurement, it also has a meaningful zero point. Ratio measurement is similar to interval measurement, but it has a unique feature whereby ratios between attributes are meaningful (e.g., weight and height). Nominal measurement, on the other hand, describes variables whose attributes are merely categorizations and cannot be compared in terms of order or magnitude. Theoretical measurement refers to measurement in the abstract sense, where the measurement scale is hypothetical and not yet empirically tested.

Question 6

Definitions are more problematic for descriptive research than for explanatory research.

Accepted Answer

Definitions are generally more problematic for explanatory research because it requires clear operational definitions to establish causal relationships, whereas descriptive research focuses on observing and describing phenomena without necessarily explaining them.

Question 7

If unsure as a researcher how specific a measurement needs to be, it is best to be more general to simplify data collection.

Accepted Answer

It is better to be more specific in measurements to ensure accuracy and reliability in data collection.

Question 8

Changing definitions almost inevitably results in different descriptive conclusions.

Accepted Answer

The answer of Changing definitions almost inevitably results in different...

Question 9

Conceptions are:

Accepted Answer

Conceptions refer to the mental images or ideas we have about something, so the best choice is (C) mental images. The other answer choices do not accurately describe what conceptions are.

Question 10

Hudson et al. developed a series of questions to examine sexual attitude scale (SAS). The SAS scores of religious fundamentalists-a group believed to be conservative regarding sexual expression-were compared with the scores of social work graduate students-a group believed to be liberal regarding sexual expression. The researchers were examining the instrument's:

Accepted Answer

The researchers are comparing the scores of two groups with different expected attitudes towards sexual expression, indicating they are testing the criterion-related validity of the instrument.

Question 11

What is validity in terms of social science research? How do social science researchers evaluate the relative validity of their measurements? Identify.

Accepted Answer

The answer of What is validity in terms of social...

Question 12

Provide one example each of how definitions are used in descriptive and explanatory studies. Why might a social scientist say that definitions are more important in descriptive studies than in explanatory ones?

Accepted Answer

The answer of Provide one example each of how definitions...

Question 13

Dr. Brown is conducting a study on opinions about gun control in the United States. How might she conceptualize and measure this subject? What are some potential biases that might affect the outcomes of her research?

Accepted Answer

The answer of Dr. Brown is conducting a study on...

Question 14

How would you measure family size at the nominal, ordinal, and ratio levels?

Accepted Answer

The answer of How would you measure family size at...

Question 15

One only needs a nominal definition of a concept before beginning the process of data collection.

Accepted Answer

The answer of One only needs a nominal definition of...

Question 16

Precise measurement is more important than accurate measurement.

Accepted Answer

Accurate measurement means that the measurement is close to the true value, while precise measurement means that the measurement is consistent. In general, precise measurement is more important than accurate measurement because it allows for more reliable and repeatable results.

Question 17

Number of arrests would be an example of an interval measurement.

Accepted Answer

Interval measurement involves numerical values that are equally spaced, and can include negative values. The number of arrests can be measured on a continuous scale and has equal intervals between values, making it an example of interval measurement.

Question 18

Professor Spence decided to define socioeconomic status as a combination of income and education. Spence then determined the questions to be asked in a survey and the categories of responses. Spence was assigning socioeconomic status:

Accepted Answer

By defining socioeconomic status as a combination of income and education and then determining the specific questions and response categories for a survey, Professor Spence is operationalizing the concept. This means Spence is providing a clear, practical method for measuring socioeconomic status in a research context, which is what an operational definition does. A nominal definition simply assigns a name to a concept without detailing how to measure it, which is not the case here.

Question 19

It is impossible to have several indicators of only one concept.

Accepted Answer

It is possible to have several indicators of only one concept because a single concept can be measured or represented in multiple ways.

Question 20

Dr. Ross is looking to examine if the indicators that make up her measurement of romantic attraction are truly related to one another and make for an accurate representation of the variable she is researching. What sort of validity is she examining?

Accepted Answer

Dr. Ross is examining construct validity, which assesses whether the indicators of a measure are related to the construct they are intended to measure.
