+
+	>| ### Close-ended questions
+	>| Questions that can be answered with a finite set of responses
+
+	>| ### Data
+	>| Raw, unprocessed facts and figures
+
+	>| ### Interview
+	>| A face-to-face meeting between people for consultative purposes
+
+	>| ### Observation
+	>| A method of data collection that involves physically observing how a system operates and how it is used
+
+	>| ### Open-ended questions
+	>| Questions where the number of potential answers is infinite
+
+	>| ### Qualitative data
+	>| Data that consists of descriptive details, usually gathered via surveys or interviews
+
+	>| ### Quantitative data
+	>| Data that can be easily processed in a statistical manner, usually composed of definite numbers
+
+	>| ### Report
+	>| A written document providing a summary or finding in relation to the context or system being analysed
+
+	>| ### Survey
+	>| A set of questions that ask for a response to be selected from a list of alternatives
