Size as small medium large 1. An obvious example is intelligence. The numbers used for measurement with ordinal data carry more meaning than those used in nominal data, and many statistical techniques have been developed to make full use of the information carried in the ordering while not assuming any further properties of the scales. Surveys tend to be more representative than experiments. One concern of measurement theory is conceptualizing and quantifying the degree of error present in a particular set of measurements and evaluating the sources and consequences of that error. Data measured on the nominal scale is always discrete, as is binary and rank-ordered data. a. For instance, if you measure the weights of a number of individuals whose true weights differ, you would not expect the error component of each measurement to have any relationship to each individuals true weight. A)Whether the measurements are the same or different B)The direction of the difference C)The size of the difference D)None of the other, Temperature is an example of a variable that uses (select one): 1. the ordinal scale 2. the interval scale 3. either ordinal or ratio scale 4. the ratio scale, An underlying assumption of regression is that both variables are measured at the \rule{2cm}{0.5pt} level?

The 0 and 1 have no numeric meaning but function simply as labels in the same way that you might record the values as M or F. However, researchers often prefer numeric coding systems for several reasons. Tuition in dollars 11. We expect that each measurement contains error, but we hope it does not include the same type of error, so that through multiple types of measurement, we can get a reasonable estimate of the quantity or quality of interest. a. Nominal b. Some types of measurement are fairly concrete: for instance, measuring a persons weight in pounds or kilograms or his height in feet and inches or in meters.

The next two sections discuss some of the more common types of bias, organized into two major categories: bias in sample selection and retention and bias resulting from information collection and recording. Another important distinction is that between continuous and discrete data. Classify the measurement type of the following example as nominal data, ordinal data, or interval-ratio data. b. assign a score. Predictive validity is similar but concerns the ability to draw inferences about some event in the future. Ratio c. Interval d. Ordinal, Classify the following data. What type of research is this? Look no further. Interval/ratio measurement is used primarily to: a. name or categorize data. Levels of measurement, also called rating scales, refer to the values that an indicator can take (but says nothing about the indicator itself). Reliability and validity are also discussed in Chapter18 in the context of research design, and in Chapter16 in the context of educational and psychological testing. There are equal intervals between the cases. The Likert scale might be the most common type of rating scale used in human-subject research. 13. d. all of the above Ordinal measurement is used primarily to: 7. classify or categorize data. Ordinal measurement used primarily to: In which of the following research strategies is the independent variable manipulated? Classify them by measurement scale. This is a decision to be made based on the context, informed by the usual standards and practices of your particular discipline and the type of analysis proposed. b. rank : 1546363 11. Like many measurement issues, choosing good proxy measurements is a matter of judgment informed by knowledge of the subject area, usual practices in the field in question, and common sense. Attitudes toward premarital sex between consenting adults (always wrong, usually wrong, sometimes wrong, never wrong) 12. In fact, any variable based on counting is discrete, whether you are counting the number of books purchased in a year or the number of prenatal care visits made during a pregnancy. Statistics can be used to: a. reduce data to more easily understood, descriptive terms. Although deciding on proxy measurements can be considered as a subclass of operationalization, this book will consider it as a separate topic. Often 5.

Nominal data B. Nominal is used for categorical data so (a) option is You could then consider the variance between this average and each individual measurement as the error due to the measurement process, such as slight malfunctioning in the scale or the technicians imprecision in reading and recording the results. Internal consistency reliability is a more complex quantity to measure than multiple-occasions or parallel-forms reliability, and several methods have been developed to evaluate it; these are further discussed in Chapter16. Identify the type of variable: Gender (male/female) A. Nominal B. Ordinal C. Quantitative, Cross-tabulation for nominal data is the conceptual equivalent of scatter plots for score data. Note that the particular system of measurement used is not as important as the fact that we apply a consistent set of rules: we can easily convert a weight expressed in kilograms to the equivalent weight in pounds, for instance. 3. copyright 2003-2023 Homework.Study.com. To take the example of evaluating medical care in terms of procedures performed, this method assumes that it is possible to determine, without knowledge of individual cases, what constitutes appropriate treatment and that records are available that contain the information needed to determine what procedures were performed.

If the two (or more) forms of the test are administered to the same people on the same occasion, the correlation between the scores received on each form is an estimate of multiple-forms reliability. When organizing a frequency table for a variable measured at the ordinal level categories should be ordered? Temperature on the Celsius scale b. To look at another common use of proxy measurement, consider the various methods used in the United States to evaluate the quality of health care provided by hospitals and physicians.

What additional information is obtained from measurements on an interval scale compared to the measurements on an ordinal scale? Statisticians commonly distinguish four types or levels of measurement, and the same terms can refer to data measured at each level. A small data set (n = 9) has the following values (3.5, 8.1, 7.4, 4.0, 0.7, 4.9, 8.4, 7.0, 5.5). Similarly, there is no direct way to measure disaster preparedness for a city, but we can operationalize the concept by creating a checklist of tasks that should be performed and giving each city a disaster-preparedness score based on the number of tasks completed and the quality or thoroughness of completion. a) Choose the correct set of hypotheses for a two-tailed test for a zero slope. d. only categorizes. A collection of articles written by scientists that have been peer reviewed Ordinal measurement is used primarily for Rank order data Interval/Ratio measurement is used primarily to Assign a score Nominal measurement is used primarily for Name or categorize data In which research strategy is the independent variable manipulated Experiment Favorite sports a) Ratio b) Nominal c) Interval d) Ordinal, Classify the following as an example of a nominal, ordinal, interval, or ratio level of measurement, and state why it represents this level: the eye color of family members, Match each of the following variables to its scale of measurement: nominal, ordinal, interval, or ratio.

Using this scale, survey makers can analyze the degree of agreement among respondents with respect to the identified order of the variables. For instance, if a high school geometry test is judged by parents of the students taking the test to be a fair test of algebra, the test has good face validity. That is, you must establish or adopt a system of assigning values, most often numbers, to the objects or concepts that are central to the problem in question.
