From Information Lost to Knowledge Gained: The Benefits of Analyzing all the Research Evidence

Data analyses should reveal truths about data. To the extent possible analyses should tell a complete picture. Data analyses should not inadvertently ignore phenomena that might be discovered in sample data sets. However, common univariate or multivariate data analysis methods tend to be based on only the means, standard deviations, and Pearson correlations. The result is that many important truths are discovered, but not the whole truth. This article illustrates in a sample data set that (a) data analyses of other properties of variables and groups are feasible and practical, and (b) such analyses may reveal important information not otherwise detectable. These extensions of common statistical methods are applicable to data analysis and interpretation issues in the social and behavioral sciences

A Case Study of the Role of a School in a Community Undergoing Rapid Gentrification

Atlanta, one of the fastest gentrifying cities in the United States, is comprised of neighborhoods near the city center amid urban wealth that suffer from severe poverty and low literacy rates. One neighborhood school has been ranked as one of the lowest in the state. To combat decades of underperformance, Atlanta Public Schools (APS) created an initiative that has helped bring this community together. The purpose of this case study, using interviews and survey data with thematic content analysis, was to understand the role of school district leadership in the creation of a new framework, replacing the original public school with a long record of failure

One is Not Enough: The Need for Multiple Respondents in Survey Research of Organizations

The need for multiple respondents per organization in organizational survey research is supported. Leadership teams’ ratings of their implementations of market orientation are examined, along with learning orientation, entrepreneurial management, and organizational flexibility. Sixty diverse organizations, including not-for-profit organizations in education and healthcare as well as manufacturing and service businesses, were included. The major finding was the large rating variance within the leadership teams of each organization. The results are enlightening and have definite implications for improved design of survey research on organizations

How Arrogant are Sales and Marketing Professionals: Perceptions of Business Students

Arrogance is a problem in business and other sectors of American society. This multi-university study assessed more than 500 business students’ perceptions of arrogance in sales and marketing environments. It also probed the arrogance issue in 12 other professions (five business-related and seven non-business occupations). Sales professionals were perceived as being more arrogant than marketers. Gender, ethnicity, and school type were found to be predictors of arrogance in marketing positions. Overall, sales were in the middle-of-thepack with respect to perceived arrogance (several professions were more arrogant and several professions were less arrogant), while marketers were considered relatively nonarrogant. Implications of this research are threefold: 1) rethinking the sales and marketing interface in organizations, 2) understanding perceptions of arrogance by future business leaders and 3) training sales and marketing professionals to be perceived as less arrogant by their internal and external customers

Egg production functions

This study estimates egg production functions from experimental data The experimental feed variables were com and soybean meal. The experiment included the four protein levels of 12, 14, 16, and 18 percent and was initiated with 566 birds in 288 cages. Bird density per cage initially was included as a variable, but results were not significant and were dropped from the analysis. Several algebraic forms were evaluated. For the overall data, a quadratic equation without an interaction term seemed most appropriate. It was used in estimating egg production, in both numbers and weights for the entire period of the experiment, as a function of com and soybean meal intake. This estimated egg production function then was used in deriving egg isoquants, marginal rates of substitution between feeds, and other quantities that relate to optimizing feed costs

A Step-by-Step Guide to Propensity Score Matching in R

Propensity score matching is a statistical technique in which a treatment case is matched with one or more control cases based on each case’s propensity score. This matching can help strengthen causal arguments in quasi-experimental and observational studies by reducing selection bias. In this article we concentrate on how to conduct propensity score matching using an example from the field of education. Our goal is to provide information that will bring propensity score matching within the reach of research and evaluation practitioners.

Page Length and Methodological Characteristics of Recently Published Doctoral Dissertations in Education

In this methodological review, we conducted a quantitative content analysis of a random sample of 107 education-related doctoral dissertations published in Proquest Dissertations and Theses database in 2011. Seven raters coded each article in terms of page lengths (overall and within each chapter), research method (qualitative, quantitative, or mixed-methods), author gender, and university characteristics (online or traditional). We found that the median education dissertation length was 161 pages long, but those page lengths differed between research methods. The median page lengths of qualitative, mixed method, and quantitative dissertations were 210, 187, and 147 respectively. The median page length of education dissertations from online universities was 44 pages shorter than education dissertations from their traditional counterparts. Contrary to previous research, we found no statistically significant relationship between gender and methods choice
