Why McNemar's Procedure Needs to be Included in the Business Statistics Curriculum

In business research situations it is often of interest to examine the differences in the responses in repeated measurements of the same subjects or from among matched or paired subjects. A simple and useful procedure for comparing differences between proportions in two related samples was devised by McNemar (1947) nearly 60 years ago. Although the technique has enjoyed widespread usage in both behavioral and medical research, it has unfortunately not received proper attention in marketing, advertising, consumer research, public relations, operations management, or organizational behavior endeavors—disciplines wherein it is particularly desirable to evaluate the significance of changes in attitudes, opinions, or beliefs regarding some campaign or strategy. Perhaps the major reason for this obscurity is simply a general lack of awareness as to its value and practical power. The McNemar test is generally not currently being taught to business statistics students. It is the purpose of this article to demonstrate the usefulness and applicability of the McNemar procedure to these aforementioned disciplines so that it may be more appropriately employed as an important confirmatory data analysis tool within the basic business statistics curriculum.

Examining the Relationship between Math Self‐Efficacy and Statistics Motivation in the Introductory Business Statistics Course: Self‐Compassion as a Mediator

Because business statistics students often experience a lack of statistical motivation, business educators need to understand the factors that influence students’ motivation levels in undergraduate‐level business statistics courses. The purpose of this study was to examine the role of math self‐efficacy and self‐compassion on students’ motivation levels and the gender differences among the main variables. The regression results showed that math self‐efficacy was a positive predictor of statistics motivation. Self‐compassion was also found to be a partial mediator of the relationship between math self‐efficacy and statistics motivation. Gender differences were also found in business students’ math self‐efficacy, self‐compassion, and statistics motivation.

Improving Students' Data Analysis and Presentation Skills: The Ocean State Circuits,Inc. Forecasting Project

Many potential employers expect that newly hired students will arrive on‐the‐job with the ability to analyze data, utilize spreadsheets, and communicate findings and recommendations. We designed the Ocean State Circuits, Inc. Forecasting Project to address these gaps in our students’ knowledge of analytical tools (such as the vlookup() function and pivot tables), their ability to write mathematical formulas in a spreadsheet, their understanding of more advanced data analysis features (e.g., regression, correlation), and their ability to communicate and present managerial conclusions. The exercise requires student teams to act as “consultants” and utilize spreadsheets to analyze and forecast the demand for a hypothetical set of products and then communicate their findings to “management” in a professionally formatted report document. A survey of students that have completed the exercise indicates that their knowledge level of the tools used in the project increased significantly from before to after they completed the case. Similarly, anecdotal feedback from employers suggests that students that have completed the exercise seem more capable of dissecting data when investigating business issues.
