Data collection and analysis

1. Data Collection: Data collection is the process of collecting and measuring the data on targeted variables through a thoroughly established system to evaluate outcomes by answering relevant questions.

   • Primary Data Collection Methods Primary data collection methods are different ways in which primary data can be collected.
     • 1. Interviews An interview is a method of data collection that involves two groups of people, where the first group is the interviewer (the researcher(s) asking questions and collecting data) and the interviewee (the subject or respondent that is being asked questions).
     • 2. Surveys & Questionnaires Surveys and questionnaires are 2 similar tools used in collecting primary data. They are a group of questions typed or written down and sent to the sample of study to give responses.
     • 3. Observation The observation method is mostly used in studies related to behavioral science. The researcher uses observation as a scientific tool and method of data collection.
     • 4. Focus Groups Focus Groups are gathering of 2 or more people with similar characteristics or who possess common traits. They seek open-ended thoughts and contributions from participants.
     • 5. Experiments An experiment is a structured study where the researchers attempt to understand the causes, effects, and processes involved in a particular process.
   • What is Secondary Data? Secondary data is the data that has already been collected through primary sources and made readily available for researchers to use for their own research. It is a type of data that has already been collected in the past.
     • Books Books are one of the most traditional ways of collecting data. Today, there are books available for all topics you can think of.
     • Published Sources There are a variety of published sources available for different research topics.
     • Unpublished Personal Sources This may not be readily available and easily accessible compared to the published sources. They only become accessible if the researcher shares with another researcher who is not allowed to share it with a third party.
     • Journal Journals are gradually becoming more important than books these days when data collection is concerned.
     • Newspapers In most cases, the information passed through a newspaper is usually very reliable.
     • Websites The information shared on websites is mostly not regulated and as such may not be trusted compared to other sources.
     • Blogs Blogs are one of the most common online sources for data and may even be less authentic than websites.
     • Diaries They are personal records and as such rarely used for data collection by researchers.
     • Government Records Government records are a very important and authentic source of secondary data.
     • Podcasts Podcasts are gradually becoming very common these days, and a lot of people listen to them as an alternative to radio.

2. Data Analytics: Data Analytics is a process that involves the molded data to be examined for interpretation to find out relevant information, propose conclusions, and aid in decision making of research problems.

3. What is Primary Data? Primary data is a type of data that is collected by researchers directly from main sources through interviews, surveys, experiments, etc. Primary data are usually collected from the source—where the data originally originates from and are regarded as the best kind of data in research.
