Document Summary
Data: units of information that are collected and analyzed to answer research questions. Data collection: the plan to collect the method. Primary: collecting the data right from the source; original. Secondary: someone is giving you the data and you are just using the data. Aims: to collect data from a population, or a sample of research participants, in order to describe them as a group. Can be mailed, electronic, face-to-face, telephone or group. Trained interviewers for face-to-face or telephone surveys. Usually in numerical form: collect yes/no responses or likert scale, add up total sum of responses for each category, calculate the number of clients who fit into each category. Non-standardized questionnaires: used if a standardized questionnaire related to our research question is not available. Standardized questionnaires provide reliability and validity scores. Unstandardized questionnaires do not report reliability and validity. We must ensure that unstandardized questionnaires at the very least have face validity. Can easily reach large numbers of people.
