Suppose, for example, that a machine fills containers with 12 ounces of a soft drink. Periodically, a production worker selects a sample of containers and computes the average number of ounces in the sample. This average, or x-bar value, is plotted on an x-bar chart. Properly interpreted, an x-bar chart can help determine when adjustments are necessary to correct a production process. Economics Economists frequently provide forecasts about the future of the economy or some aspect of it.
They use a variety of statistical information in making such forecasts. For instance, in forecasting inflation rates, economists use statistical information on such indicators as the Producer Price Index, the unemployment rate, and manufacturing capacity utilization.
Often these statistical indicators are entered into computerized forecasting models that predict inflation rates. Such examples provide an overview of the breadth of statistical applications. To supplement these examples, practitioners in the fields of business and economics provided chapter-opening Statistics in Practice articles that introduce the material covered in each chapter.
The Statistics in Practice applications show the importance of statistics in a wide variety of business and economic situations. All the data collected in a particular study are referred to as the data set for the study. Table 1.
These stocks are closely followed by investors and Wall Street analysts. TABLE 1.
For the data set in Table 1. With 25 stocks, the data set contains 25 elements. A variable is a characteristic of interest for the elements.
The data set in Table 1. The set of measurements obtained for a particular element is called an observation. Referring to Table 1. A data set with 25 elements contains 25 observations. Scales of Measurement Data collection requires one of the following scales of measurement: nominal, ordinal, interval, or ratio. The scale of measurement determines the amount of information contained in the data and indicates the most appropriate data summarization and statistical analyses.
When the data for a variable consist of labels or names used to identify an attribute of the element, the scale of measurement is considered a nominal scale.
For example, referring to the data in Table 1. In cases where the scale of measurement is nominal, a numeric code as well as nonnumeric labels may be used. For example, to facilitate data collection and to prepare the data for entry into a computer database, we might use a numeric code by letting 1 denote the New York Stock Exchange and 2 denote the Nasdaq National Market.
In this case the numeric values 1 and 2 provide the labels used to identify where the stock is traded.
The scale of measurement is nominal even though the data appear as numeric values. The scale of measurement for a variable is called an ordinal scale if the data exhibit the properties of nominal data and the order or rank of the data is meaningful.
For example, Eastside Automotive sends customers a questionnaire designed to obtain data on the quality of its automotive repair service. Each customer provides a repair service rating of excellent, good, or poor. Because the data obtained are the labels— excellent, good, or poor—the data have the properties of nominal data.
In addition, the data can be ranked, or ordered, with respect to the service quality. Data recorded as excellent indicate the best service, followed by good and then poor. Thus, the scale of measurement is ordinal.
