有许多不同的方法，可以应用在采集数据时。据walliman（2010）数据分为两类；定性和定量数据。定性数据的基础是了解其他人的意见，来描述一个问题，发展成一个方法。定性取决于词义的谨慎的描述、概念和变量之间的关系，绘制这些进步。的概念，如人的判断力，舒适的感觉，情绪，思想，信仰等，只能用语言描述。Â常见的数据集合进行深入访谈、焦点小组、文学文本、历史记录或观察。定性数据依赖于人的解释和评价，不能以通常的方式客观测量。在一致性和定性数据的广泛性检查可以通过一系列有关同一事件的数据源来完成的，称为三角（walliman，2010）。这是'的见解，而不是世界统计感知”（Bell，2005）。定量研究可以更精确地因为它包括某种程度的测量，数字通常表示。数学程序可以用来分析数据（walliman，2010）根据贝尔（2005）可用于研究一系列事实与他人的关系。这些可以是简单如数量或百分比或进一步成熟，如统计试验或科学模型。这类集合实例调查与问卷.

There are many different approaches that can be employed when collecting data. According to Walliman (2010) data is divided into two categories; qualitative and quantitative data. Qualitative data is grounded on understanding opinion of others, to describe a problem and develop into an approach. Qualitative depends on cautious description of the meaning of words, the progress of concepts and variables and plotting the relationships between these. Concepts such as People's judgement, feeling of comfort, emotions, ideas, beliefs etc. can only be described in words.  Common data collections used are in-depth interviews, focus groups, literary texts, historical records or observations. Qualitative data rely on human interpretation and evaluation and cannot be objectively measured in a typical way. Checks on consistency and extensiveness of qualitative data can be completed by referring a range of source of data relating to same event, called as triangulation (Walliman, 2010). It is the 'insights rather than statistical perceptions of the world' (Bell, 2005).Quantitative research can be measured more precisely because it comprises some form of extent, usually expressed in numbers. Mathematical procedures can be used to analyse the data (Walliman, 2010) and according to Bell (2005) can be used to 'study the relationship of one set of facts with another'. These can be mostly simple such as amounts or percentages or further sophisticated, such as statistical trials or scientific models. Examples of this type of collection are surveys and questionnaires (Walliman,2010).
