Quantitative Research
Research Methodology and Research Design
We determine the statistical method for the study that you plan to conduct. For example, what should the sample size for your research be? Which technique should we apply to the data?
In addition, we assist you in the design phase of your research. The type of research design you use is important for finding reliable and valid results. Additionally, we can help you make this decision.
Selection of the Variable
Researchers select variables based on the hypothesis that they test. For example, we use our statistical expertise when selecting research variables.
Sample Size
Statistical expertise is necessary when selecting the sample size. For example, if the sample size is small, the statistical test will not give accurate results. However, if the sample size is too large, the research project will be costly. Therefore, we can determine the ideal sample size.
Data Management
Our statistical consultants can organize, code, merge, clean, and manage your data. In addition, we can get your dataset ready for analysis. Additionally, we create composite scores, work with missing data, and label data.
Test Statistics
Our statistical consultants determine the test statistics for particular data and research questions. For example, there are many statistical tests used for specific reasons. Additionally, we are experts in a variety of these statistical tests. Therefore, we validate your data plan to make sure it examines your research questions.
Our statistical consultants conduct descriptive statistics, assess assumptions, and conduct data analysis. In addition, we write up all the results, including tables and figures. We also provide syntax and the raw output file. Finally, our statisticians ensure you are comfortable with the analyses.
Reliability and Validity
In any research, only conducting the analysis is not enough. Therefore, we ensure that the results are reliable and valid.
Interpretation of the Results
Our statistical consultants interpret and present the research results. We also explain the results of the study. Additionally, our statisticians allow unlimited email and phone support to ensure that you completely understand the analysis results.
Qualitative Research
Our consultants can help you with any or all of the following steps:
- Establishing and operationalizing your research questions
- Providing ample instruction on the methods used
- Coding, thematizing and providing reporting of findings for a study
- Identifying themes and sub-themes
- Coding documents to count the word-phrase clusters
- Creating a word-phrase cluster in the form of classified conceptual categories to count those conceptually categorized words or phrases
- Addressing specific subthemes that the thematic constructs have
- Providing numerical frequencies and standard scores for each master theme and sub-theme
- Writing up all results, including APA tables and figures
- Explaining the results
- Allowing unlimited e-mail and phone support to ensure that you completely understand the results of the analysis.

Examples of Our Work
Internet Use
Our statistical consultants measured the impact of internet use on perceived performance. We performed a regression analysis to determine that internet use significantly affected perceived performance (β = 0.82, p < 0.05). [...]
Relative Risk of Lung Cancer
We compared the difference in relative risk (RR) of lung cancer between the intervention and control groups. The intervention group exhibited an increase in RR of lung cancer from pre to post (p < 0.05). [...]
Blood Pressure
A global hospital hired our statistical consultants to compare the difference in blood pressure between patients with cancer and patients without cancer. Thus, we found a significant difference in blood pressure between patients with [...]
Financial Performance
We measured the impact of banking fees on financial performance. Banking fees significantly and positively affected financial performance (β = 0.46, p < 0.05). We performed a regression analysis by using SPSS. [...]

Independent Samples T-Test
The independent-samples t-test is used to determine if a difference exists between the means of two independent groups on a continuous dependent variable. More specifically, it will let you determine whether the difference between [...]
Binomial Logistic Regression
A binomial logistic regression attempts to predict the probability that an observation falls into one of two categories of a dichotomous dependent variable based on one or more independent variables that can be either [...]
Paired-Samples T-Test
The paired-samples t-test is used to determine whether the mean difference between paired observations is statistically significantly different from zero. The participants are either the same individuals tested at two time points or under [...]
Regression Analysis
A simple linear regression assesses the linear relationship between two continuous variables to predict the value of a dependent variable based on the value of an independent variable. More specifically, it will let you: [...]
