Firm Type

Apple, interested in learning about the effect of firm types on performance, approached our team. Apple sought to understand the underlying factors contributing to performance and identify potential areas.

To tackle this problem, we had access to a substantial dataset primarily consisting of survey data. The data comprised demographic information related to 9,000 firms, and the study spanned six years. This rich dataset served as the foundation for our analysis, providing valuable insights into the characteristics of the firms under investigation.

The hypothesis was as follows: H1 – There is a significant difference in performance based on firm type over time. We aimed to test the hypothesis rigorously and determine whether firm type indeed played an important role in influencing performance outcomes.

We conducted a mixed Analysis of Variance (ANOVA) using the statistical software Stata to analyze the data and evaluate our hypothesis. A mixed ANOVA was chosen as the appropriate analytical method because it allowed us to compare the means of performance across multiple categories of firm types over time, thus helping us identify any statistically significant differences.

Our findings from the mixed ANOVA analysis were pivotal in shedding […]

Marketing Strategy

Accenture Interactive hired our team because it noticed a divergence in consumer behavior and brand image associated with its various marketing strategies. We recognized the importance of understanding these differences and delved deeper into the dynamics between marketing strategies and consumer perceptions. To do so, we had access to a substantial dataset of survey responses from 5,000 consumers spanning two years.

The dataset primarily comprised survey data, which allowed us to gather valuable insights into consumer preferences, perceptions, and behaviors. The hypothesis was as follows: H1: There is a statistically significant difference in consumer behavior and brand image based on the various marketing strategies. We tested the hypothesis using Multivariate Analysis of Variance (MANOVA), utilizing the statistical software SPSS to conduct the analysis. MANOVA is most appropriate for assessing whether there are statistically significant differences in multiple dependent variables across different groups or levels of an independent variable, which aligns perfectly with the project’s objectives of comparing the effects of various marketing strategies on consumer behavior and brand image.

The findings from our MANOVA analysis were pivotal in addressing Accenture Interactive’s initial concern. Our results revealed a statistically significant difference […]

Energy Savings

NextEra Energy sought to explore the effect of solar panel installation on homeowners’ energy savings. Recognizing the growing interest in renewable energy sources and sustainability, NextEra Energy embarked on a comprehensive research initiative to investigate whether adopting solar panels led to significant home energy savings.

To address this inquiry comprehensively, we had access to a substantial dataset of survey responses from a significant sample of 12,000 homeowners. The study spanned a comprehensive seven-year period, providing valuable longitudinal insights into the relationship between solar panel installation and homeowners’ energy savings.
We utilized survey responses to gather pertinent information related to homeowners’ energy usage, installation of solar panels, and the resulting energy savings. This dataset served as the foundation for our analysis, enabling us to delve deep into the potential effects of solar panel adoption on homeowners’ energy efficiency.

The hypothesis was H1 – Solar panel installation significantly affects homeowners’ energy savings. To rigorously test this hypothesis, we employed logistic regression, utilizing the statistical software R. We selected logistic regression as the appropriate analytical method due to its suitability for modeling binary outcomes, which was the presence or absence of significant energy savings.

The findings from our […]

Mathematics Performance

We were involved in a research project commissioned by the National Science Foundation. The project’s objective was to explore the effect of motivation on students’ mathematics performance. The client, committed to advancing education and understanding the factors that influence academic achievement, wanted to investigate the role of motivation in mathematics performance using data from the Third International Mathematics and Science Study (TIMSS) conducted in 1999.

The project leveraged data from the TIMSS 1999 study, which included a diverse sample of 500,000 students from various participating countries. This dataset encompassed a wide range of grade levels, making it one of the most significant international assessments of student achievement in mathematics.

The hypotheses were as follows:
H1 – Intrinsic motivation positively influences mathematics performance, while external regulation impacts it negatively.
H2 – A positive mathematics self-concept significantly affects mathematics performance.
H3 – A positive mathematics self-concept significantly affects intrinsic motivation, affecting mathematics performance.
H4 – Autonomy support in the classroom significantly affects mathematics performance.
H5 – Autonomy support in the classroom significantly affects mathematics self-concept, affecting mathematics performance.

We adopted a comprehensive data analysis approach to evaluate the hypothesis. We performed Structural Equation Modeling (SEM) and Multilevel Path Modeling analyses using […]

Political Parties

This research project, funded by the National Science Foundation, aimed to investigate whether there were discernible differences in political party affiliation based on age. The client recognized the significance of understanding the difference in political party preferences based on age and thus initiated this study using a comprehensive dataset of survey responses from 12,000 participants over five years.

We conducted a chi-square test using SAS, a statistical software, to thoroughly evaluate the hypothesis that there were significant political party differences by age. This chi-square test proved an effective statistical tool for assessing the association between categorical variables. This chi-square test is most appropriate for investigating differences in political party preferences across various age groups.

The analysis revealed that there was indeed a statistically significant difference in political party affiliations based on age, indicating that age played an important role in shaping individuals’ political preferences and party affiliations. The client was able to derive valuable insights from this research project, which could inform political campaigns, outreach strategies, and policy initiatives tailored to specific age groups.

This National Science Foundation-funded project provided essential insights into the interplay between age and political party affiliations. By rigorously testing […]

Depression

This research project, funded by the National Institutes of Health (NIH), aimed to address a pressing concern related to the mental health and well-being of students – the potential difference in depression levels between students who have experienced bullying and their peers who have not. The project conducted a comprehensive survey-based study using a robust dataset comprising survey responses from 13,000 students to gain insights into this critical issue. The dataset was collected over six years, allowing for an in-depth examination of depression levels among both bullied students and their non-bullied peers.

We formulated the central hypothesis guiding the research as follows: H1 – There is a significant difference in depression between bullied students and their peers over time. We performed a mixed ANOVA using the statistical software R, a powerful statistical tool for comparing means between two groups over time and well-suited for investigating differences in depression levels over time.

The analysis yielded compelling findings that shed light on the client’s inquiry. The research revealed a statistically significant difference in depression levels between bullied students and their peers who had not experienced bullying over time. Specifically, bullied students had higher levels of […]
