There are a number of approaches used in this research method design.

Data collection is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical and social sciences , humanities , [2] and business. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same. The goal for all data collection is to capture quality evidence that allows analysis to lead to the formulation of convincing and credible answers to the questions that have been posed. Data collection and validation consists of four steps when it involves taking a census and seven steps when it involves sampling [3].

Research Design and Methodology

Now that you have determined what outcomes or other aspects of your program to evaluate, it is time to identify what type of data to collect and how to collect those data. Keep in mind that there is no single best evaluation design or way to collect data. The most appropriate approach is the one that will answer your evaluations questions within the limits of the resources available to you. One of the first aspects you need to consider is what type of data will best meet your needs. The type of data you choose to collect - quantitative or qualitative - is in part dependent on what you want to know about your program.

While data analysis in qualitative research can include statistical procedures, many times analysis becomes an ongoing iterative process where data is continuously collected and analyzed almost simultaneously. Indeed, researchers generally analyze for patterns in observations through the entire data collection phase Savenye, Robinson, The form of the analysis is determined by the specific qualitative approach taken field study, ethnography content analysis, oral history, biography, unobtrusive research and the form of the data field notes, documents, audiotape, videotape. An essential component of ensuring data integrity is the accurate and appropriate analysis of research findings. Improper statistical analyses distort scientific findings, mislead casual readers Shepard, , and may negatively influence the public perception of research.

The underlying need for Data collection is to capture quality evidence that seeks to answer all the questions that have been posed. Through data collection business or management can deduce quality information that is a prerequisite for making informed decisions. To improve the quality of information, it is expedient that data is collected so that you can draw inferences and make informed decisions on what is considered factual. At the end of this article, you would understand why picking the best data collection method is necessary for achieving your set objective. Data collection is a methodical process of gathering and analyzing specific information to proffer solutions to relevant questions and evaluate the results.
