Find baseline data for youth in a mentoring program, identify all variables, input the data into Excel, save as a CSV file, and modify data types in JASP according to their measurement level (nominal, ordinal, or scale). Note that analysis is not required at this step.

The process of data management is a fundamental aspect of research methodology, especially in social sciences and program evaluation. It involves collecting, organizing, and preparing data for analysis, ensuring that variables are correctly identified, measured, and formatted. For a program evaluation, such as a mentoring initiative aimed at at-risk youth, it is essential to accurately input baseline data to facilitate meaningful analysis later. This paper discusses the importance of variable identification, proper data entry, data type classification, and the use of software like Excel and JASP to prepare datasets for statistical evaluation.

In the context of program evaluation, variables are characteristics or attributes that can vary among individuals within the sample population. Proper identification of these variables ensures accurate data analysis, which is critical for deriving valid conclusions about the program's effectiveness. The given dataset includes various variables such as age, ethnicity, gender, credits earned, GPA, self-esteem scores, attendance, and behavioral ratings. Each of these variables plays a distinct role in understanding the youth's baseline status and predicting potential changes post-intervention.

The first step in data management is to collect data systematically. In this scenario, the baseline data for youth participants are provided, with specifics about their demographic, academic, and behavioral characteristics. After gathering this data, the next step involves inputting it into a spreadsheet software such as Microsoft Excel. Data should be entered carefully, ensuring accuracy and consistency across entries to avoid errors that could compromise the validity of subsequent analyses. For each variable, the corresponding data is entered into appropriate columns, creating a structured dataset.

Once data entry is complete, the dataset is saved as a comma-separated values (.csv) file. CSV format is widely used because it is compatible with many statistical software packages, including JASP. Saving data in CSV allows for seamless data import and supports clean, comma-delimited formatting that preserves data integrity. Proper naming conventions for files and organized data structures facilitate later analysis and review.

After exporting the CSV file, the dataset is imported into JASP, a user-friendly statistical software that supports various analyses. In JASP, the next crucial step is to modify the data type of each variable to reflect the correct measurement scale. There are three main types: nominal, ordinal, and scale. Nominal variables are categorical without inherent order, such as ethnicity and gender. Ordinal variables have a natural order, for example, self-esteem scores ranging from 1-30. Scale variables are continuous and quantitative, such as GPA, credits, and days missed. Correctly classifying variables is essential because it influences the choice of statistical tests and interpretation of results.

This process—inputting data, saving as CSV, importing into JASP, and adjusting data types—is a fundamental skill for researchers and practitioners conducting program evaluations or any quantitative research. It ensures that the dataset is accurately prepared for analysis, supports reproducibility, and enhances the integrity of research findings. Accurate initial data entry and proper data type assignment set the foundation for valid, reliable statistical testing, ultimately contributing to informed decision-making and evidence-based practice in social services and education sectors.
