Experimental designs involving the randomization of cases to treatment and control groups are powerful and under-used in many areas of social science and social policy. This paper reminds readers of the pre-and post-test, and the post-test only, designs, before explaining briefly how measurement errors propagate according to error theory. The…

Plaza del Valle is an open-air shopping center in the San Fernando Valley region of Los Angeles. The new marketing manager must review primary and secondary data to determine a target market, a product positioning strategy, and a promotion strategy for the retail shopping center with the ultimate goal of increasing revenue for the Plaza. She is…

This paper analyzes the power relation between the interviewer and the interviewee in the qualitative research interview methodology. The paper sets out to grapple with the extent to which the dynamisms in power shifts influence data collection and analysis in the interview methodology. The exploration of power shifts in the qualitative research…

Bayesian estimation for 2 groups provides complete distributions of credible values for the effect size, group means and their difference, standard deviations and their difference, and the normality of the data. The method handles outliers. The decision rule can accept the null value (unlike traditional "t" tests) when certainty in the estimate is…

Despite wide applications of both mediation models and missing data techniques, formal discussion of mediation analysis with missing data is still rare. We introduce and compare four approaches to dealing with missing data in mediation analysis including list wise deletion, pairwise deletion, multiple imputation (MI), and a two-stage maximum…

Rapid advances in data-rich domains of science, technology, and business has amplified the computational challenges of "Big Data" synthesis necessary to slow the widening gap between the rate at which the data is being collected and analyzed for knowledge. This has led to the renewed need for efficient and accurate algorithms, framework,…

Large real-world graph (a.k.a network, relational) data are omnipresent, in online media, businesses, science, and the government. Analysis of these massive graphs is crucial, in order to extract descriptive and predictive knowledge with many commercial, medical, and environmental applications. In addition to its general structure, knowing what…

A variety of joint space multidimensional scaling (MDS) methods have been utilized for the spatial analysis of two- or three-way dominance data involving subjects' preferences, choices, considerations, intentions, etc. so as to provide a parsimonious spatial depiction of the underlying relevant dimensions, attributes, stimuli, and/or subjects'…

Despite Civil Rights legislation, racial inequality persists, especially in the context of poverty. This study advances the literature on racial inequality and the Southern legacy of slavery by examining slavery's relationship with inequality in poverty. I analyze county-level U.S. Census data using regression and spatial data analysis techniques.…

We propose functional multiple-set canonical correlation analysis for exploring associations among multiple sets of functions. The proposed method includes functional canonical correlation analysis as a special case when only two sets of functions are considered. As in classical multiple-set canonical correlation analysis, computationally, the…

Prior research in higher education shows that engagement has been inconsistently conceptualized: semantic inconsistency has been compounded by variations in the constructs used to operationalize engagement. Acknowledging these limitations, we conceptualize student engagement as a multi-faceted meta-construct, overcoming some of the limitations…

The current study aims to identify teacher and administrator views regarding primary school principals' accountability. The case study model, a qualitative research method, was adopted in the study using the holistic single-case design. The working group was composed of a total of 56 individuals, 42 teachers and 14 administrators (11 principals…

This study examines the relationship between spousal support and the ability to express feelings of marital satisfaction, and the extent to which spousal support and the ability to express feelings can predict marital satisfaction. Research was conducted in accordance with general survey models. The study group comprised 195 married couples (N =…

The need to train and engage all school counselors in use of data drives professional development at the district and state level. This study examined previous training in the use of data and the degree to which that training influenced current school counseling practices. Data were collected from 512 school counselors across a Midwestern state.…

Substantial amount of research regarding L2 learners' beliefs has been conducted in recent years. However, not enough attention has been paid to investigating the nature of learners' beliefs; hence our understanding of the construct is contradictory in the sense that early research studies report stability in beliefs, while more recent studies…
