in the study. This method provided access to a specific population that was readily available and relevant to the research focus, ensuring that the data collected would reflect the experiences and perspectives of those actively involved in sweetpotato farming.
Research Design
The descriptive survey design was chosen for its effectiveness in gathering detailed information about a specific phenomenon—in this case, the practices, challenges, and perceptions of sweetpotato farmers. By using a qualitative approach within a predominantly quantitative framework (through the use of close-ended questionnaires), the research aimed to capture both numerical data and nuanced insights.
This design allowed researchers to:
- Quantify Responses: By employing close-ended questions, it was possible to categorize and quantify the responses easily, facilitating statistical analysis.
- Gain Insight: A qualitative approach enabled researchers to explore farmers' attitudes and experiences, providing deeper context to the quantitative data.
Sampling Technique
The convenience sampling method was particularly suited for this research due to several factors:
- Accessibility: Farmers present at the Goroka Main Market were readily accessible, which streamlined the data collection process.
- Relevance: Targeting farmers specifically involved in sweetpotato production ensured that the sample was relevant and representative of the population of interest.
- Time Efficiency: Given the logistical constraints of working within a specific timeframe, convenience sampling allowed researchers to gather data quickly without the need for an elaborate sampling framework.
Data Collection Process
The data collection process involved the following steps:
-
Preparation of Questionnaires: Close-ended questionnaires were designed to capture essential information regarding farmers' practices, challenges faced, and perceptions about sweetpotato farming.
-
Engagement in the Market: Researchers visited the Goroka Main Market on designated days, approaching farmers as they conducted their marketing activities.
-
Consent and Participation: Farmers who were present and willing to participate were approached for their input. Participation was voluntary, and informed consent was obtained to ensure ethical standards were met.
-
Data Compilation: Responses were collected and compiled for analysis. Given the nature of the questions, responses were likely to be coded numerically for statistical assessment.
Limitations of the Sampling Technique
While convenience sampling has its advantages, it also comes with limitations:
- Selection Bias: The sample may not adequately represent the larger population of sweetpotato farmers since it only includes those present at a particular location at a specific time.
- Lack of Generalizability: Findings from this sample may not be generalizable to all sweetpotato farmers in the region or in other settings, as those who frequent the market may have different characteristics compared to those who do not.
Conclusion
In conclusion, this research design and sampling technique were tailored to facilitate effective engagement with a specific group of sweetpotato farmers in Goroka. While convenience sampling poses certain limitations, it enabled the researchers to collect valuable data that could inform insights into the production and marketing of sweetpotatoes, contributing to a better understanding of the agricultural landscape in the area. Future research could consider employing random sampling techniques or expanding the study to include a more diverse range of participants to enhance the robustness of the findings.
